Polyurethane open timing belts are manufactured from thermoplastic polyurethane material. They have good anti-wear qualities, strong tensile strength, and excellent abrasion resistance. They also exhibit high durability, flexibility, and power transmission capacity. They are widely used in various applications such as high-speed drives, positioning applications, miniature drives, and small handheld machines.

Polyurethane open timing belts are produced in the open length. They have a tensile cord, which is made of stainless steel, Kevlar, or aramid fiber. The cord is bonded to the polyurethane body to produce a reliable and strong transmission. The tensile cord gives the belt a good elasticity and flexibility. This enables it to be accurately positioned.

Polyurethane open timing belts have a fine size stability and a wide range of application possibilities. They are also manufactured in state-of-the-art production processes. PU open timing belts are available in numerous widths.

Several types of rubber materials are available to make the belt resistant to high temperatures. These rubbers improve the abrasion resistance and distortion resistance of the belt. The belt has an abrasion-resistant tooth profile and a smooth tooth back. The surface layer of the belt depends on the machine type.

Polyurethane open timing belts can be joined together to make any length. However, this process requires the proper sizing. This can be done by calculating the center to center distance of the belt. The resulting effective tension is then divided by the strength factor.

In addition, the pulley diameter and the belt width must be compatible to meet the torque of the design. If the diameter of the pulley is too large, the teeth of the belt might cog over the pulley. If the width of the belt is too narrow, the load might be too large for the belt. Moreover, dust particles might accumulate on the belt.
