OVERALL FEATURES

DIAMOND TREAD is ABEAR Industrial’s improvement on the standard rubber pulley lagging, engineered to reduce the Total Cost of Ownership. It delivers reliable traction.

The advanced anti-resonance and anti-vibration design further enhances the conveyor system performance by extending the lifespan of key mechanical components, including bearings, gearboxes, and other elements of the conveyor system.

The reduced Total Cost of Ownership is achieved not only through extended pulley lagging service life, but also through smoother system operation and reliable traction and tracking.

The tread grooves shed material to ensure consistent traction and reliable belt tracking.
