PU V-Belts

PU V-Belts

The high modulus polyurethane compound (PU) used to construct Gates PU V-belts is tested and trusted to resist wear, fatigue, and ozone damage for a longer, more reliable working service life. Gates precision-manufactures our PU V-belts to eliminate layers and overlaps for smooth running and low vibration, designed to service a range of light duty and precision equipment applications. For custom sheaves and assemblies, contact the Gates Made-to-Order Metals team.
