Main Advantages (Derived from the Hollow Design)
Enables Built-in Lubrication Channels: This is the most core and significant advantage. The hole through the center of the pin allows lubricant (oil or grease) to be delivered directly from an external source (such as a grease nipple or centralized lubrication system fitting) to the critical friction pair inside the pin and bushing (or roller). This delivers:
Efficient and Precise Lubrication: Lubricant reaches the friction points (pin-bushing/roller) that need it most, reducing waste.
Extended Chain Life: Continuous and sufficient lubrication significantly reduces wear, increasing the service life of both the chain and sprockets.
Reduced Maintenance Workload and Downtime: Enables automatic lubrication, eliminating the need for frequent shutdowns for manual greasing. This is especially beneficial for hard-to-reach equipment or machinery requiring continuous operation.
Improved Hygiene Conditions: Prevents lubricant splashing and leakage, making it particularly suitable for industries with high cleanliness requirements like food and pharmaceuticals.
Adaptability to Harsh Environments: The oil passages protectively deliver lubricant to the friction points, resisting the ingress of dust, moisture, and other contaminants.
Facilitates Connection and Fixation:
Quick Installation and Removal: Using the hollow hole to insert a cotter pin, locking pin, or bolt simplifies connecting the chain (using a connecting link) and securing it to the frame.
Provides Attachment Mounting Points: Offers additional fixing options for attachments on conveyor chains.
Weight Reduction:
The hollow structure naturally reduces the overall weight of the chain compared to solid pins. This is highly advantageous for high-speed drives, long-distance conveying, or applications with strict overall weight requirements, as it lowers inertia, improves responsiveness, and reduces energy consumption.
Potential Heat Dissipation Benefit:
Increases the surface area (internal and external) of the pin, and the internal cavity facilitates airflow. This offers a slight improvement in heat dissipation performance compared to solid pins.
