Polyurethane Timing Belts Catalog

The Material: Polyurethane (PU)ï¼›steel or kelvar cord

including the open end timing belts, sleeve timing belts, flex truly timing belts

These belts use steel tension cord encased in a polyurethane jacket with integral teeth. The method of manufacture ensures tight control of pitch length for applications where accurate positioning is required. Polyurethane is a non-crumbling, non-marking material with excellent resistance to mineral oils, greases and light acidic solutions making it an ideal material for food applications, on cigarette pressing machines and paper transporting systems.
Polyurethane belt drives are available in 3 pitch sizes, 2.5mm (T2.5), 5mm (T5 & AT5) and 10mm (T10 & AT10), with a selection of pilot bore pulleys. Double sided belts and long open end belt lengths are also available. For reciprocating drives clamping plates are available to retain the belts.
A new range of PU belts to operate on standard HTD pulleys is available in 5mm, 8mm and 14mm pitch in open end construction for high load reciprocating drives.

Manufactured in urethane with continuous helically wound steel cable cords, Jason's Uniflex belts are ideal for situations where high stress and load demands exceed the performance capacity of spliced belts or where the "tooling cost" of long length or non-standard endless belts are prohibitive. Truly endless and any length, Uniflex timing belts are suitable for all power transmission, high speed and sever conveying applications.

Jiver urethane belts can be made up with a variety of welded-on profiles to handle your specific applications. These profiles can be used as indexers, actuators, carriers, or pushers. They can provide accuracy in assembly, packaging and inserting operations. Custom profile designs are possible. jivers Uniflex belts are available from 1500 to 13,000 MM lengths and a maximum width of 150 MM.

open end polyurethane timing belts


Ideal for linear drive and indexing applications, Jiver's Polyurethane open end belts are available in a variety of sizes, pitches and colors to meet all specifications. Belt styles include steel or Kevlar reinforcement, as well as high load (HP) and high flexibility (HPF). Belts can be spliced to specified lengths. Nylon fabric (PAR) is available on backside for low friction transport, as are high abrasion resistance and FDA-approved polyurethane backings. Nylon fabric (PAZ) is also available on the tooth side for low friction and noise reduction. Standard and non-standard widths available in pitch XL, L, H, XH, T5, AT5, T10, AT10, T20, AT20, 5MM, 8MM, and 14MM.




Sleeve polyurethane Timing belts



For power transmission and linear positioning, jiver Industrial's polyurethane timing belts are designed for strength, ease of use and minimum maintenance. Polyurethane timing belts are available in all popular standard and metric pitches. Dual-sided belts are available in T5 and T10 pitches. We stock 300mm sleeves and can provide any required width from stock. Kevlar tensile cord can be substituted for steel on special orders.
