  • HBD Thermoid
  The Complete V-Belt Line
Prime Mover  

Premium rated heavy industrial V-belt.
Oil-resistant and static® conducting. This one versatile V-belt — sized in A, B, C, D, E sections — can power virtually every drive in your plant.

Prime Mover Cogged Belts  

A premium construction belt for tough applications. Cogged belts offer great flexibility and increased capacity of a drive system.

Maxipower™  

A premium construction wedge-type, multiple drive belt that provides equal power transmission capacity in less space than ordinary multiple type belts. And it’s oil-resistant and static conducting at the same price. Operates at speeds up to 6500 FPM. Sizes 3V, 5V and 8V sections.

Maxipower Cog Belts  

These belts are ideal for situations where weight or sheave size is restricted. This belt delivers maximum efficiency on small sheaves. Its raw edge cogged narrow wedge construction is excellent for use with high speed motors.

Prime Mover Banded Belts  

A unitized set of premium construction belts that is vulcanized to form a belt set. The individual V’s are spaced to permit operation in MPTA standard groove belt sheaves. This design prevents belt whip and turnover under pulsating and shock loads. Oil and heat resistant.

Prime Mover Banded Belts  

A unitized set of premium construction belts that is vulcanized to form a belt set. The individual V’s are spaced to permit operation in MPTA standard groove belt sheaves. This design prevents belt whip and turnover under pulsating and shock loads. Oil and heat resistant.

Maxipower Banded Belts  

Premium Maxipower V-belts are bonded together to form a unitized belt set. Individual V’s are spaced to permit it to operate in regular multiple groove 3V, 5V, 8V sheaves. This construction prevents belt whip and turnover under pulsating and shock loads. PowerPlus Maxiband® V-Belts with aramid reinforced cord are also available.

 

 

Maxipower™ Cogged Banded Belts  

Raw edge Maxipower Cogged Banded belts deliver maximum efficiency on small sheaves. Ideal for high speed motors where banded construction prevents belt whip and turnover.

Powerplus™ Maxiband™ Belts  

These belts are designed for high horse power, high tension, and severe shock load applications. Super tough aramid cords with maximum internal adhesion have far more heat resistance and far less stretch than other cords. The cover is designed to protect the carcass from abrasion, heat, oil and to prevent static buildup.

Grip-Tite HT Curvilinear Timing  

Grip-Tite HT belts bring the advantages of synchronous rubber belts to applications previously served by roller chain and gear drives. These belts do not require lubrication and, therefore, maintenance costs are minimized, and contamination from oil drip is eliminated.

Grip-Tite and Mini-Pitch Timing  

Functions like a timing chain or gear. Precision-molded teeth engage the mating axial grooves on pulleys, entering and leaving the grooves in a smooth, rolling manner with negligible friction. Highly versatile in application, load and speed range. Also available in Mini-Pitch.

Dual Timing  

Timing belts with driving teeth on both sides make it possible to change the direction of one or more synchronized pulleys with only one belt. The inside and outside teeth are identical as to size and pitch.

Metriflex  

Made to strict European tolerances and specifications to assure a highly accurate fit for metric drives. Sizes XPZ, XPA, XPB, SPC.

Double V Belts  

Used where a series of shafts rotating in opposite directions must be driven from a single source of power. Either side of the belt can be used as a driving surface.

Variable Speed

 

For drives where variable speed control drives and mechanisms are employed. Belts’ transverse rigidity gives it excellent gripping action without crosswise distortion.

Novex  

This lightweight, versatile polyurethane belt has a unique design and side angle construction that allows for small sheave diameters, greater speed ratios and shorter centers.

FHP Glasstex® ORS and PowerPlus™  

For light duty service FHP offers cool, quiet operation and long service life. Because of its glass cord construction, it will not shrink or stretch. It’s oil resistant and static conducting, all at a standard price. For heavy-duty service, PowerPlus belts with aramid cord are available.

PowerPlus™ Belts  

Designed to withstand the rigors of tough, frequent usage in lawn and garden equipment, home workshop equipment, hobby center power tools, as well as in severe industrial drives. They withstand severe shock load and provide generally longer life than standard duty belts. They are oil and heat resistant.

Aramid Cord  

We recommend our PowerPlus™ line, or aramid reinforced A and B sections which are stock items, since steel cable Prime Mover belts are no longer available. Aramid reinforced C and D sections are special order items. Power Plus A’s and B’s, along with aramid C’s and D’s, offer higher heat resistance than steel cable and minimal stretch.

Open End Belting  

For drives not easily accessible to install endless V-belts, for for emergency use. Required length is cut off and its ends joined by a metal fastener. Available in Prime Mover cross-section for lower operating speeds.

V-Link  

An open-end belt that doesn’t require metal fasteners, for use where obstructions prevent use of endless belts. Can be quickly and easily installed without dismantling a drive. Available in Prime Mover cross-sections.

Dual Timing  

Timing belts with driving teeth on both sides make it possible to change the direction of one or more synchronized pulleys with only one belt. The inside and outside teeth are identical as to size and pitch.
