Gates 7M545 (8903-0545) Polyflex Belt

The Gates Polyflex V-belt is engineered for high-speed drives on small-diameter sheaves that exceed the minimum bend radius of standard V-belts. The unique polyurethane body and aramid cord construction delivers superior power capacity in a compact profile.

Where this product is used

Gates Polyflex V-belts are designed for high-speed drives on small-diameter sheaves where standard V-belts cannot operate. Typical applications include:

• High-speed, small-diameter sheave drives in textile machinery, woodworking and precision equipment
• Applications where a standard V-belt cannot achieve the required minimum sheave diameter
• Energy-efficient drives benefiting from Polyflex's low-mass, high-flex design characteristics

Key specifications

Selecting the right option

Polyflex belts are available in 3M, 5M, 7M and 11M cross-sections — the number indicates the top width in mm. Select by cross-section and pitch length to match your existing drive specification. The 7M section is the most common industrial Polyflex size. Gates Polyflex JB joined belts (Polyflex JB) are the banded equivalent for multi-groove sheaves.
