Brewer Machine & Gear B5015H Idler Roller Chain Sprocket

Brewer B5015H is a steel A-Style, single-strand idler roller chain sprocket designed for 50-chain drives. It features 15 teeth, a 5/8 in bore and an outer diameter of 3.32 in, optimized for a 5/8 in pitch chain, and is available with a ball bearing to reduce friction in rotating assemblies. This idler guides and tensions the chain within Brewer’s Universal Drive Tensioner family and related Brewer drive systems, helping maintain alignment and smooth operation in compact, single-strand configurations. When installed in such systems, the B5015H contributes to stable chain tracking and wear resistance by providing a robust steel hub with bearing support for the chain path. Common applications include use as an idler element in Brewer tensioners and other single-strand chain drives where precise chain guidance and durable performance are required.
