Block Chains

1 Inch Pitch Chain

RM Fowler stock a range of 1 inch pitch block chain ideal for use on early cycles, starting handles for many cars and pedal chains for early motorcycles. The chain we supply is the laminated type made of laminated steel plates which offers a greater strength than the solid sintered type of chain.

Due to the design of this chain the pitch is measured between alternate pins, please see the diagram below which also includes other dimensions.

B = Block width
D1 = Inner Plate height
D2 = Outer Plate height
G = Pin diameter
H = Pin length or total width
