Round Belt Idlers Engineered for Performance

- Quiet, Low-Friction Performance: The natural lubricity of our plastics creates a smoother, quieter pull, reducing system wear and extending the life of your belts.
- Idler & Drive Pulley Versatility: Our pulleys function perfectly as free-spinning round belt idler pulleys and can be instantly converted into round belt drive pulleys using our range of drive adapters.
