FAQ

What is the material of this pulley and does it have a pilot bore?

This pulley is typically manufactured from high-grade grey cast iron (EN-GJL-200) or steel. It comes with a standard pilot bore that needs to be machined (bored, keywayed, and set-screwed) to your specific shaft requirements.

Is this pulley compatible with both HTD and OMEGA 8M timing belts?

Yes, the 8M tooth profile used by Optibelt is compatible with standard 8M HTD (High Torque Drive) and Optibelt’s own OMEGA timing belts, ensuring versatile application in various drive systems.

How do I ensure correct belt tension when using this 44-8M-20 pulley?

Proper belt tension is critical for performance and longevity. It is recommended to use a tension gauge (like an Optibelt TT frequency meter) to set the tension according to the drive design calculations provided by Optibelt’s software or general engineering guidelines for 8M belts.
