Premium V-Belt Drives

Premium belts have the highest power density of any V-belt, and stretch dramatically less than standard cross sections. That’s why they’re ideal for use on problem drives requiring high-impact strength and load-carrying power.

Premium Banded Belts

Replaces 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 Single Belts

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.

Product Features

  • "Clutching” non-rubber surfaced cover allows momentary slippage due to excessive overloads without burning belts up.
  • KEVLAR* or aramid tensile cords give extraordinary strength, durability and virtually zero stretch.
  • Virtually zero stretch eliminates the need for constant belt re-tensioning.
  • 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. This yields uniform loading, giving maximum belt life and even wear on the sheave sidewalls (eliminates dishing).
  • Double fabric cover creates maximum abrasion resistance that protects against wear caused by fine airborne dust in rock quarries and lumber mills, which can cause rapid belt sidewall wear resulting in early failures.
  • Over 20-50 percent more horsepower than standard V-Belts enables new equipment designers to utilize the full load-carrying capacity of these high-performance belts.

Product Features

  • Convenient Sure-Grip® QD type bushings
  • Fine grain, high tensile cast iron construction
  • vBelts transmit more horsepower than classical V-belts
  • Four belt types: Cog V-belts, Cog Banded V-belts, V-belts, and Banded V-belts

TB Wood’s Classical (also known as Conventional) V-belts include five cross sections: A, B, C, D, and E. These sections are a continuing development of the original V-belts of the 1930’s. A, B, C, and D belts are available in wrapped or cog construction and all are static conducting, and oil and heat resistant.

Note: E section V-belts are available for replacement on existing drives, but are not recommended for new drive designs.

Product Features

Classical Cog:

  • 30% higher horsepower rating than standard belts, on average
  • Premium raw edge, cog construction

Classical Banded:

  • Designed for problem drives
  • Multiple belts integrated into single belt

Classical:

  • Cover fabric offers optimal flexibility and abrasion resistance
  • Finest wrapped belts in the industry

Classical Cog Banded:

  • Available in BX, CX and DX belts in 2 through 5 ribs
  • Premium raw edge, cog construction

TB Wood’s light-duty sheaves are available in two types, both with one and two grooves. "AK" sheaves are made to accommodate A (4L) belts; "BK" sheaves are made for A (4L) or B (5L) belts. The two lines of sheaves have identical pitch diameters when using A or 4L belts. Wood’s light-duty sheaves can be equipped with Wood’s "QT" Sure-Grip QD-type bushings, quick-detachable tapered bushings that are split through flange and tapered surface to provide a true clamp that is comparable to a shrink fit.

Product features

  • Easy-mount, Sure-Grip® Quick Detachable (QD) bushings
  • Bored to size from 1/2 TO 1-1/2 inches
  • Capacities to 15 horsepower
  • Efficient, economical and lightweight

The Wood’s Poly-V sheaves include four cross sections: J, K, L, and M. The J section sheaves are stocked in a Sure-Grip QD Style and also bored-to-size for sheaves under 2”. The K, L, and M sections are available on a made-to-order basis in either cast or ductile iron and in Sure-Grip or bored-to-size design.
