20T Idler Series

The 20T Idler Series is designed for smooth belt guidance and reliable tension control in timing belt–driven motion systems. These idler pulleys help maintain proper belt alignment, reduce friction, and ensure stable, quiet operation in continuous-use environments.

With a 20-tooth (20T) profile, this series is suitable for multiple belt pitches and is widely used in automation systems, CNC machines, and 3D printer assemblies where precision and durability are required.
