Premium banded V-belts from TB Wood’s (Chambersburg, PA) are designed for drives requiring high impact strength and load-carrying power. Banded belts feature a multiple-layer tie band that provides lateral rigidity to prevent belts from turning over or from coming off the drive. Premium singles are available for applications where banded belts are not an option. Single belts can be used with deep-groove sheaves and drives with limited room for take-up.
A clutching non-rubber surfaced cover allows momentary slippage due to excessive overloads without burning up the belts. Kevlar or Aramid tensile cords yield virtually no stretch. Chloroprene rubber compounds provide oil and heat resistance, and the cover withstands slip and shear forces at peak loads without generating excessive heat. The curve design compensates for effects such as sidewall bulge, which occurs when belts bend around a sheave.
