Varibelt Polyurethane Open End Timing Belts
Varibelt® Polyurethane Open End Timing Belts production includes the widest range of high performance profiles, allowing the users to select the best technical solution in every drive application.
1 – Thermoplastic polyurethane 92 ° Sh.A with high wear resistance.
2 – Tension cords parallel to the edges can be made of steel with high tensile strength and high elastic modulus or can be made of Kevlar for more strength and flexibility and lighter belt weight
3 – Varibelt® Polyurethane Open End Timing Belts can be produced with special coating on the teeth or on the back. The coating selections are Transparent Polyurethane (with a hardness of 85 Shore A), PAZ, PAR, Linatex, APL, PU, PVC, PVC Supergrip, Formed PU, Sponge, Fishbone, Ribbed, AVAFC, Cleats, Grooves, Punched and Notched. The special coating is used in order to;
• reduce friction
• improve tooth engagement
• and reduce the noise.

Varibelt VX® V-belts exceed USA RMA published ratings levels.
Varibelt VX® V-belts are manufactured to meet the same RMA/ISO Standards as all other major American or European Manufacturers’ belts of the same type. Designed to perform at identical or higher levels, Varibelt VX V-belts and Agrobelt V-belts are dimensionally and functionally equivalent to V-belts produced by major American and European manufacturers.
Now made with EPDM (Ethylene Propylene Diene Monomer), a synthetic rubber with outstanding properties, VARIBELT VX® Varibelt® Polyurethane Open End Timing Belts are static conductive, more durable, and more resistant to heat, hardening, and glazing than ever before.
