Premium V-belt drives

Premium V-belt drives have high power density and stretch dramatically less than standard cross sections, making them suited for use on problem drives requiring high-impact strength and load-carrying power.

Premium belts can replace several belts with the strength of a single belt. Banded belts feature a multiple layer tie band for lateral rigidity to prevent belts from turning over or coming off the drive. Premium Singles are for applications when banded belts cannot be used. Single belts can be used with deep groove sheaves and drives with limited room for “take up.” They can also be an “A” section solution for multigroove A/B sheaves.

A “clutching” nonrubber-surface cover allows momentary slippage due to excessive overloads without burning the belts up. The belt’s curved design compensates for effects such as sidewall bulge, which occurs when belts bend around a sheave. A double fabric cover creates maximum abrasion resistance to protect against wear caused by fine airborne dust, which causes rapid belt-sidewall wear. Sheaves are available with capacities up to 600 hp and bore sizes from ½ to 8½ in.
