BASIC INFO
 

Insert bearing with housing is a kind of bearing unit which combines rolling bearing with bearing housing. Most of the outer spherical bearings are made of spherical outer diameter, which are installed together with the imported bearing pedestal with spherical inner hole. The structure is diverse and has good versatility and interchangeability.

The outer spherical ball bearing is actually a variant of the deep groove ball bearing, which is characterized by the spherical outer diameter surface of its outer ring, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of self-aligning. Outer spherical bearing is mainly used to bear radial and axial combined load which is mainly radial load. Generally, it is not suitable to bear axial load alone.

The outer spherical bearing with seat is a kind of high precision component product composed of grease sealed deep groove ball bearing and various shape bearing seats. The bearing assembly can be directly installed on the main body of the mechanical device through several bolts. It has the function of self-aligning and can supplement the grease. It is a very simple product for installation and use.

External spherical bearing

English Name: insert bearing

Features: the outer diameter surface of its outer ring is spherical

Load: mainly in radial direction

Subject: Mechanical Engineering

Although its basic performance and deep groove ball bearing should be similar, but because this kind of bearing is mostly used in relatively rough machinery, installation and positioning is not accurate enough, the axis of the shaft and seat hole is not neutral, or the shaft is long and deflection is large, and the bearing itself is not high enough precision, some structure is also relatively rough, so the actual performance of the performance is relatively the same specification Deep groove ball bearings should be given a considerable discount. For example: the outer spherical ball bearing with jacking wire is applied to the through shaft with large deflection and stiffness difference. This kind of bearing has sealing rings on both sides, which can strictly prevent the invasion of dirt. It has been filled with an appropriate amount of lubricant when leaving the factory. It does not need to be cleaned or added with lubricant before installation. When the jacking screw on the protruding end of the bearing inner ring is fastened on the shaft, the allowable axial load shall not exceed 20% of the rated dynamic load.

The performance of the outer spherical ball bearing with eccentric sleeve is basically the same as that of the outer spherical ball bearing with jacking wire, but the jacking wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered hole outer spherical ball bearing is a tapered hole with a taper of 1:12, which can be directly installed on the tapered shaft, or installed on the shoulderless shaft with the help of the tightening bush, and the bearing clearance can be adjusted.

It is mainly used to bear the combined radial and axial load with radial load as the main load. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with inner ring (with a full set of rollers and retainer) and outer ring respectively. This kind of bearing does not allow the shaft to tilt relative to the shell, which will produce additional axial force under radial load. When the axial clearance is too small, the temperature rise is high; when the axial clearance is large, the bearing is easy to damage. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre interference installation can be used to increase the rigidity of the bearing.

At the same time, this kind of bearing also has a certain degree of self-aligning in design, easy to install, and has a double structure sealing device, which can work in harsh environment. The bearing block is generally cast. The commonly used seats are vertical seat (P), square seat (f), boss square seat (FS), boss round seat (FC), diamond seat (FL), ring seat (c), slider seat (T), etc.

USED

Spherical bearings are preferred for applications requiring simple equipment and parts, such as agricultural machinery, transportation system, construction machinery, cotton and hemp machinery, combine harvester, firewood machinery, fan, light load transmission device, etc.

PILLOW SPHERICAL BEARINGS CATEGORYOF 

Outer spherical bearing with seat is a high precision component product composed of grease sealed deep groove ball bearing and bearing seat of various shapes. The bearing assembly can be directly installed on the main body of the mechanical device through several bolts. It has the function of self-aligning and can supplement the grease. It is a very simple product for installation and use.

Outer spherical ball bearing with pedestal

Outer spherical bearing with seat is a kind of bearing unit which combines rolling bearing with bearing seat. Most of the outer spherical bearings are made of spherical outer diameter, which are installed together with the bearing seat with spherical inner hole. The structure is diverse, and the versatility and interchangeability are good.

At the same time, this kind of bearing also has a certain degree of self-aligning in design, easy to install, and has a double structure sealing device, which can work in harsh environment. The bearing block is generally cast. The common seats are vertical seat (P), square seat (f), boss square seat (FS), boss round seat (FC), diamond seat (FL), ring seat (c), slider seat (T).

Outer spherical bearing with seat is divided into bearing center and bearing seat, which is called bearing center plus bearing seat. For example, outer spherical bearing with set screw uc205 is called UCP205 with vertical seat. Because of the strong interchangeability of the spherical bearing with pedestal, the bearing core can be assembled in the bearing pedestal with the same specification and different shapes at will.

According to the method of cooperation with spherical bearings, they can be divided into three categories

I. The codes of the outer spherical ball bearing with top wire are uc200 series (light series), uc300 series (heavy series) and deformation product UB (sb) 200 series. If the application environment is small, uc200 series is usually selected, otherwise uc300 series is selected. Usually, there are two jacking wires on the outer spherical ball bearing, and the included angle is 120 degrees. Its characteristic is that when cooperating with the shaft, the jacking wire is used to jack on the shaft, and then has a fixed effect. However, the environmental demand of cooperation is necessary, and the oscillation scale is small. This kind of spherical ball bearing is widely used in textile machinery, ceramic machinery and other manufacturing professions.

II. The taper outer spherical ball bearing is named uk200 series and uk300 series. The taper bore with inner diameter of 1:12 share of this kind of outer spherical ball bearing should be used in cooperation with the tightening sleeve. The characteristic of this kind of outer spherical ball bearing is that it can accept more load than the outer spherical ball bearing with top screw. For example, the inner diameter of uc209 is 45mm, and the diameter of the shaft cooperating with uc209 is 45mm, If the taper outer spherical ball bearing is replaced, only the 45 mm inner diameter tightening sleeve can be selected, while the 45 mm tightening sleeve can only cooperate with the uk210 taper outer spherical ball bearing (of course, if it fits higher, uk310 can be selected). Therefore, the agreement accepted by uk210 is much larger than that of uc209.

III. The codes of outer spherical ball bearing with eccentric sleeve are: uel200 series, uel300 series and sa200 series. The main feature of this kind of spherical ball bearing is that the upper end of the bearing has a certain degree of deflection, and the deflection sleeve with the same degree of deflection cooperates with it. This kind of bearing can also be said to be a special bearing. Because it is mainly used in agricultural machinery (harvester, straw returning machine, thresher, etc.), this kind of spherical ball bearing is mainly used in the layout with strong beating, and the cooperation of partial layout can effectively reduce the strong IIF


MAINTENANCE

I Cleaning

When the bearing is removed for inspection, take photos and other methods to make appearance records. In addition, the amount of remaining lubricant should be confirmed and the lubricant should be sampled before cleaning the bearing.

II Inspection

In order to distinguish whether the removed bearing can be used from the beginning, it is necessary to check its standard accuracy, rotation accuracy, internal clearance, and the wear condition of cooperation surface, raceway surface, bracket and sealing ring. The inspection effect can be distinguished and judged by the habitual bearing or the reasonable bearing users. In addition, the inspection cycle and detection parameters are different according to the mechanical function and the importance of relevant factors. If the above damage can not meet the re-use requirements, the bearing shall not be used from the beginning, it is necessary to replace.


DISASSEMBLY AND INSTALLATION

390000 series outer spherical bearings are fixed with the inner ring of the bearing and the shaft through the eccentric sleeve, and the inner hexagon screw on the eccentric sleeve plays a tightening role. During maintenance, many operators can't disassemble this kind of bearing, so it's necessary to introduce the technical points and precautions for disassembling 390000 series spherical bearings

I Disassembly

1. First loosen the locking screw on the bearing eccentric sleeve with an internal hexagon wrench, then insert a small iron bar into the counterbore on the top cover eccentric sleeve, and loosen the eccentric sleeve against the rotation direction of the shaft.

2. Loosen the bolts fixing the bearing pedestal. Remove the bearing together with the bearing pedestal from the shaft. Before removing the bearing block at one end of the shaft, loosen the bearing block bolts at the other end of the shaft to avoid damage caused by mutual stiffness of the bearings at both ends.

II Installation

1. Before installing the bearing on the shaft, the fixing pin of the bearing sleeve must be pulled out, the surface of the journal must be polished and cleaned, and the journal must be oiled for rust prevention and lubrication (the bearing is allowed to rotate slightly on the shaft).

2. Apply lubricating oil on the matching surface of bearing seat and bearing, and install the bearing into the bearing seat. Then put the assembled bearing and bearing seat together on the shaft and push them to the required position for installation.

3. Don't tighten the bolts to fix the bearing seat, let the bearing sleeve rotate in the bearing seat. Similarly, install the other end bearing and seat on the same shaft, rotate the shaft for several turns, and let the bearing itself automatically find the correct position. Then tighten the bolts of the bearing seat.

4. Install eccentric sleeve. First, put the eccentric sleeve on the eccentric step of the bearing inner sleeve, and tighten it by hand in the direction of rotation of the shaft. Then, insert the small iron bar into or against the counterbore of the eccentric sleeve. Knock the small iron bar with a hammer in the direction of rotation of the shaft to make the eccentric sleeve firmly installed. Finally, lock the hexagon screw on the eccentric sleeve.
