Variable Speed Belts
Variable speed drives demand a unique combination of belt features. Because these belts are wide in proportion to their thickness, they must have extreme crosswise rigidity, or else the belt would dish in, throw the tensile cords out of alignment and affect speed control. Recommended for use on variable speed sheave drives requiring exact speed control and maximum range of speed changes.

Poly V-Belts J, K, L, M
Poly v-belts are ultra flexible belts with ribs in the bottom that mate with the sheave grooves of a similar shape and offers distinct advantages which include: the use of smaller, less costly sheaves, smoother, vibration free performance, high speed capability, space-saving compact design, higher efficiency than conventional v-belts, and serpentine drive capability. A poly v-belt is a single belt so there is no wasted space between sheave grooves, no matching problems, and no belt turnover.

Neoprene Timing Belts
1. Neoprene Backing – The extra double, highly flexible neoprene backing provides excellent abrasion and wear resistance – especially important if power is transmitted from the back of the belt. Backing also guards the tensile cords against oil, grease, dirt and moisture.
2. Tensile Cords – Continuous, helically wound high strength fiberglass tensile cords guarantee dimensional stability to eliminate take up adjustments. Heavy Torque loads won't fatigue this super strong cord.
3. Teeth – Precision formed, oil and heat resistant neoprene teeth have a shear resistance equal to the tensile strength of the belt. Tooth design and tight manufacturing tolerances provide a constant circular pitch to assure full surface contact between belt and pulley for smooth running characteristics
4. Facing – The tooth surface is protected by a low friction, clean running, wear resistant woven nylon facing. Seamless construction eliminates vibration.

Polyurethane Timing Belts
Polyurethane timing belts provide a lightweight drive system when used with aluminum or plastic pulleys, and exceptionally quiet operation. They are ideal for applications needing high oil and ozone resistance, and their extremely clean operation make the suitable for appliance and office machine use. Metric sizes are often found on imported textile machinery.

1. Body – Body is made from the highest quality polyurethane for maximum oil and ozone resistance. Non-static conductive.
2. Tensile Cord – Strong steel cords, which won't stretch or fatigue over the life of the belt, provide high load carrying capacity and superior tooth shear strength under shock load applications.

Dual Sided Neoprene Timing Belts
1. Body – Flexible neoprene body resists oil, heat, ozone, grease and moisture for long belt life.
2. Tensile Cords – Strong, helically wound cords won't stretch or fatigue under high horsepower loads.
3. Teeth – Durable, precision formed teeth engage pulley grooves for accurate synchronization from both sides of belt.
4. Facing – Tough nylon fabric on both sides of the belt protect teeth against wear and abrasion. Low coefficient of friction provides smooth running characteristics.

Double Sided Polyurethane Timing Belts
1. Body – Top quality oil and ozone resistant polyurethane provides clean running operation and exceptionally long belt life.
2. Tensile Cords – In metric sizes, steel cords assure length stability and stand up to horsepower loads. In RMA sizes, the tensile cord is high strength Kevlar® fiber.
