Optibelt Red Power 3V

Maintenance-free narrow wedge belts · 3/8″ (9.5mm) wide · Fits standard 3V pulleys

Optibelt Red Power is a high-performance, maintenance-free wedge belt from Optibelt, our premier brand. Once correctly fitted and tensioned, it doesn’t need re-tensioning, and it carries more power than a standard 3V belt, so drives run longer between services with less downtime. It’s ideal for fans, rooftop HVAC units, pumps, compressors and any drive that’s hard to reach or runs around the clock. Search by the code on the old belt, such as 3V500, and use the filters to narrow it down by length.

Getting the best from Red Power

Reading the code3V500 means a 3V belt with a 50.0 inch effective (outside) length. Red Power belts use the same sizes as standard 3V belts, so the code on your old belt is all you need.

Upgrading a driveBecause Red Power carries more power, you can often replace standard 3V belts like for like for longer life, or run fewer belts on the same drive. Ask us if you’d like help reviewing a drive.

Fit it rightMaintenance free depends on correct installation. Check the pulleys for wear, align them accurately and tension the belts to Optibelt’s recommended value using a tension gauge.

Tip: on multi-belt drives, replace every belt at once and don’t mix Red Power with standard belts on the same drive.
