1. Three Basic Dimensions
Pitch, Roller Diameter and Inner Width are referred to as the “Three Basic Dimensions of Roller Chain.” When these three sizes are identical, roller chains and sprockets are dimensionally compatible.

2. Basic Parts
Link Plate
The plate may be the component that bears the strain positioned on the chain. Generally that is a repeated loading, occasionally accompanied by shock. As a result, the plate should never only have great static tensile power, it must also endure to the powerful forces of load and shock.

Pin
The pin is at the mercy of shearing and bending forces transmitted by the plate. Simultaneously, it forms a load-bearing part (alongside the bush) when the chain flexes during sprocket engagement. Therefore, the pin needs high tensile and shear power, resistance to bending, and must also have sufficient stamina against shock and use.

Bush
The bush is subject to complex forces from all parts, especially from the repetition of shock loads when the chain engages the sprocket. For that reason, the bush needs incredibly high shock resistance. Furthermore, the bush forms a load-bearing part together with the pin and therefore requires great wear level of resistance.

Roller
The roller is at the mercy of impact load since it mates with the sprocket teeth during engagement of the chain with the sprocket. After engagement, the roller changes its point of contact and balance. It is held between your sprocket teeth and bush, and moves on the tooth face while getting a compression load. For that reason, it must be resistant to use and still have power against shock, exhaustion and compression. (RS25 and RS35 are bush chains and do not have rollers).

Roller Link
Two bushes are press match two roller link plates and rollers are inserted to allow rotation around the outside of the bushes during operation. This is the same for solitary and for multi strand chains.

Pin Hyperlink and Drive Chain intermediate Plate
The pin link contains two pins that have been press fit into two pin hyperlink plates. In case of multi-strand roller chain up till size 08B, an intermediate plate can be added to the pin hyperlink. In case of multistrand roller chain above size 08B, two intermediate plates are added to the pin hyperlink. The intermediate plates are slide fit for regular roller chain and press fit for SUPER roller chain.
