Multiple Plate Bearing Pin Chains MP Series
A multiple plate bearing pin chain is a type of timing chain that uses many rows of plate-type bearings. It is often used in automotive engines. These chains use a short pin to hold the plates in place. These chains are highly efficient and require less maintenance than conventional chain systems. They are especially useful in high-performance applications.

A multiple plate bearing pin chain has two types: the hollow type, which allows attachments to fit through the pin itself, and the solid type, which is thicker and more durable than the hollow variety. Hollow bearing pin chains are generally used in light-duty applications, while solid bearing pin chains are typically used in more intensive conveyor applications. Both types have their benefits, so choose the one that fits your specific needs. Deep link chains are different from other chains, which use a single plate. They have deeper side plates than the standard chain plates, giving them a continuous carrying edge over the roller’s periphery.

Multiple Plate Bearing Pin Chains MP Series Features
There are many features of multiple plate bearing pin chains, including the ability to accommodate a wide range of attachments.Conveyor systems usually use these chains, and the above section shows their sizes. Because the pin is at the center of articulation, the pitch length remains constant throughout the chain’s motion. Because of this, the center distance for attachments is always the same, even if the chain bends or the sprocket is engaged.
Hollow bearing pin chains are more flexible, allowing for attachments to be loosely affixed to the chain. Solid bearing pin chains are thicker and fuller, making them appropriate for more demanding conveyor applications. Lastly, deep link chains are deeper than standard chain plates, offering a steady carrying edge atop the roller. Both types feature solid or hollow bearing pins. This type of chain is generally more expensive, and its higher tension limits make it the ideal choice for demanding conditions.
