Frequently Asked Questions

Q: What is the difference between Steel and Cast Iron H-series pulleys?

Steel pulleys offer higher tensile strength and impact resistance for heavy-duty loads, while Cast Iron provides excellent vibration damping and wear resistance for high-speed stability.

Q: Why choose a Pilot Bore over a Finished Bore pulley?

Pilot bores provide the flexibility to machine the pulley to your exact shaft diameter locally, eliminating errors associated with standardized sizes and ensuring a precision interference fit.

Q: Which H-profile size should I choose (H075 to H300)?

The choice depends on your torque requirements and belt width. Larger profiles like H200 and H300 are designed for heavy industrial loads, while H075 is suited for lighter, high-precision applications.

Q: How do I prevent belt slippage with these timing pulleys?

Our H-series pulleys use a positive-drive tooth profile that mechanically locks with the belt, virtually eliminating slip compared to V-belt systems.

Q: Are these pulleys compatible with standard timing belts?

Yes, they are manufactured to strict industry standards for H-profile timing belts, ensuring compatibility across most major industrial belt brands.

Q: What is the typical lead time for custom bore machining?

Since these are pilot bore pulleys, they are available for immediate shipping. The final bore machining is typically performed by the end-user or a local machine shop upon delivery.
