Can Pulleys of Different Brands Be Mixed?

Can Pulleys of Different Brands Be Mixed? Full Guide

Many people ask: Can pulleys from different brands be used together?

The answer depends on the tooth profile, not just the brand.

Let’s take a look at mainstream brands today.

Common belt brands on the market:

Optibelt (Germany)

All deliver reliable quality. The key for mixed use is matching tooth profiles.

Optibelt pulleys mainly feature these tooth profiles:

HTD

RPP

STD

HTD and GT are widely used high-torque tooth profiles.

Gates pulleys mainly come with two tooth profiles:

HTD

GT is Gates’ flagship tooth profile.

Please follow these two rules:

· Optibelt Omega tooth profile cannot be paired with STD pulleys.

· Gates GT tooth profile cannot be paired with STD pulleys either.

Simply remember this rule:

Pulleys and belts from different brands are compatible only if their tooth profiles are identical.

Examples:

· Gates HTD pulley → Works with Optibelt HTD belt

· Optibelt RPP pulley → Use RPP belt instead of STD belt

· Optibelt Omega belt → Matches only Omega pulley, not STD pulley
