Product Description

The 20-S8M Timing Pulley is a precision-engineered synchronous power transmission component designed for industrial belt drive systems. This S8M Belt Pulley 20 Tooth model features a trapezoidal tooth profile with 20 teeth, optimized for S8M-compatible polyurethane or rubber timing belts. Its standard bore accommodates direct shaft mounting while supporting axial loads up to 180N, with operating temperatures ranging from -30°C to +85°C. The 20 Tooth S8M Sheave is CNC-machined from grade 6061 aluminum (anodized option available), offering precise 8mm pitch synchronization for conveyor systems, packaging machinery, and robotic actuators. Compatible with standard 15mm belt widths, it enables efficient torque transfer in 24V DC industrial environments. Key advantages include zero-backlash operation and corrosion resistance, though requires precise belt tensioning. Incorporates dual set screw fixation and optional encoder-ready designs for motion control integration.
