Because of the material makeup of rivetless drop forge conveyor chains, they are often found in lightly corrosive applications such as car washes, automotive industry, material handling, meat packing, overhead conveyors, poultry processing, sugar processing, and many more general conveying and trolley conveyor type applications.
Something important to note about this chain is just because it is an X458 conveyor chain does not mean that it is an equivalent to other manufacturers. Though dimensionally the same, our drop forged chains use the best metallurgy sources, fully heat-treated and hardened pins, and is quality inspected through every process to ensure the end result is a premium long-lasting chain. This is why we can rate our chain at an ultra high 48,000 LBS tensile strength and it is one of the most widely used X458 chains in the industry.
X458 conveyor chain is apart of the rivetless drop-forge chain type within Engineer Class chains. This is because the links of X-458 chain are manufactured from a forged steel-cast material and can be easily assembled as well as disassembled.

Drop Forged Rivetless Chain
| - All SMCC drop forged chains are commonly used in overhead conveyor systems and automated material handling systems. |
| - SMCC drop forged chain offers increased flexibility. |
| - All chain components are heat treated to achieve greater durability and extended chain life. |
| - Precise pitch control and smooth bearing area for optimal wear life. |

X458 Chain Disassembly
Because of its design, X458 conveyor chain is extremely easy to assemble and disassemble and it does not require any special tools to do so. This is one of the reasons why this chain is so commonly used in applications because of the ease in making repairs or replacing.
CHAIN STANDARDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An "H" following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, "10 speed chain". Hub gear or single speed bicycles use 1/2" x 1/8" chains, where 1/8" refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at one and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.
