POWERTWIST Drive Belting
The long-lasting upgrade to rubber belts – engineered to handle the demands of the harsh environments found in mining and aggregate applications.
- Easy, fast installation – belts are made to the required length by hand and roll on to the drive without dismantling drive system components
- Longer belt life – extremely high strength and low elongation under load results in increased belt longevity and durability
- Reduce inventory – eliminate the need to purchase and inventory numerous belt lengths
- Harsh environments – highly resistant to abrasive dust and rock particles, water, oils, grease, common industrial solvents, and extreme temperatures of -40°F to +240°F (-40°C to +116°C)
- Belt Selection – available in Z/10, 3L, A/13, B/17, C/22, and D32 classical profiles (red) and 3V, 5V, SPZ, SPA, and SPB metric wedge profiles (blue) to cover all of your drives
- No change in set-up – drops right in to standard pulleys
