Premium belts from TB Wood’s have the highest power density of any V-belt, and stretch dramatically less than standard cross sections which makes them ideal for use on problem drives requiring high-impact strength and load-carrying power.

Premium Banded belts can replace several belts with the strength of a single belt. Banded belts feature a multiple layer tie band that provides excellent lateral rigidity to prevent belts from turning over or from coming off of the drive. Premium Singles are available for applications when banded belts are not an option. 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 multi-groove A/B sheaves.

TB Wood’s Premium V-belts can handle 1.4 to 2.2 times more horsepower than equivalent sized standard V-belts, so you can design a more compact drive that weighs less, puts less strain on costlier components, and uses fewer belts. A “clutching” non-rubber surfaced cover allows momentary slippage due to excessive overloads without burning belts up. KEVLAR or Aramid tensile cords yield extraordinary strength, durability and virtually zero stretch. Chloroprene rubber compounds provide superb oil and heat resistance. Specially-treated extra tough cover withstands slip and shear forces at peak loads without generating excessive heat; fends off penetration by foreign materials. Curve design compensates for effects such as sidewall bulge, which occur when belts bend around a sheave. A double fabric cover creates maximum abrasion resistance that protects against wear caused by fine airborne dust which can cause rapid belt sidewall wear resulting in early failures.
The exceptional strength of Premium belts, combined with tough application environments, may require extra heavy-duty TB Wood’s sheaves that can meet the challenge. TB Wood’s sheaves are carefully engineered to assure maximum performance over a long life span. They’re constructed of fine grain, high tensile cast iron. A full array of sheaves is available to meet specific application requirements with capacities up to 600 HP from stock and bore sizes from 1/2 to 8-1/2 inches.
