Roller chain 20B-1, pitch 31.75 mm (1 1/4"), with straight plate, C45 steel

Product Description

Roller chain 20B-1, pitch 31.75 mm (1 1/4"), with straight plate, C45 steel is a single-strand roller chain with a pitch of 31.75 mm (1 1/4"), compliant with DIN 8187 / ISO 606.

The plates have a straight (non-waisted) profile, so the chain can slide on a guide rail or carry the load directly on the plates. Ozdowski brand chains are made of C45 steel, and each element - pin, bush, roller and plate - is hardened separately before assembly. As a result, their strength is up to approx. 20% higher than the standard requires.
