Roller chain – simplex and duplex
![Roller chain simplex Roller chain simplex](/products/products-ms/timing-drive-systems/roller-chain/180/image-thumb__180__fieldcollection_image-text/rollenkette_simplex.jpg)
The acoustically optimized chain with gap damping between roller and bush plus excellent wear resistance for high-speed applications.
Simplex and duplex roller chains with a 3/8" pitch are used primarily in timing drives, oil pump drives and drives for auxiliary units, especially for petrol engines.
Owing to its smaller pitch, a roller chain with an 8 mm pitch cuts the weight and consequently reduces the centrifugal forces and impact speed. It is therefore ideal for downsizing to timing drives with moderate loads.
