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

2. Basic Parts
Link Plate
The plate may be the component that bears the tension placed on the chain. Usually that is a repeated loading, occasionally accompanied by shock. Consequently, the plate should never only possess great static Stainless Steel Chain tensile strength, it must also endure to the powerful forces of load and shock.

Pin
The pin is subject to 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, level of resistance to bending, and must have sufficient stamina against shock and put on.

Bush
The bush is subject to complex forces from all parts, especially from the repetition of shock loads when the chain engages the sprocket. As a result, the bush needs extremely high shock resistance. In addition, the bush forms a load-bearing part alongside the pin and as such requires great wear level of resistance.

Roller
The roller is subject to impact load as it mates with the sprocket teeth during engagement of the chain with the sprocket. After engagement, the roller changes its stage of contact and stability. It is held between your sprocket tooth and bush, and progresses the tooth encounter while receiving a compression load. As a result, it must be resistant to wear and still have strength against shock, fatigue and compression. (RS25 and RS35 are bush chains and don’t 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 one and for multi strand chains.

Pin Link and Intermediate Plate
The pin link includes two pins which have been press fit into two pin link plates. In case of multi-strand roller chain up till size 08B, an intermediate plate can be put into the pin hyperlink. In the event of multistrand roller chain above size 08B, two intermediate plates are put into the pin hyperlink. The intermediate plates are slip fit for regular roller chain and press fit for SUPER roller chain.
