Overview
The Martin 35B24 is a precision roller chain sprocket engineered for industrial power transmission and motion control applications. This single-pitch Type B hub sprocket delivers reliable, efficient performance in conveyor systems, machinery drives, and automation equipment. Built from high carbon steel with non-hardened teeth and manufactured to ANSI standards, the Martin 35B24 provides consistent mesh with #35 roller chain while minimizing runout through concentric bore design.
Key Features
- 24 teeth, #35 chain pitch (3/8 inch) for standard ANSI roller chain compatibility
- High carbon steel construction with consistent finish and precise machining
- Type B hub with 2.000″ hub diameter for compact, efficient power transmission
- Concentric bores to pitch line — minimizes runout and ensures optimal chain engagement
- Reboreable stock bore design allows custom boring up to 1.375″ maximum diameter
- ANSI standard tolerances exceed industry specifications for proven reliability
