Inturduction of pu timing belts
PU timing Belts are manufactured in thermoplastlc polyurethane. It has strong anti-wear. It has small production tolerance.PU timing belt has the reliable transmission and the fine size stability. A layer of nylon can be added in the tooth face and/orback in order to guarantee the running specialty in the special applications; also can added a thick layer of polyurethane inthe back of the belt to resist corrosion or high loading. Different core can be used to meet different demands. Core types:Steel, Stainless steel, Kevlar.
Belt types: Open Belt (M), Joined Belt(V), Endless Belt(Flex).
A new-generation power transmission belt made of polyurethane, combining precise, positive drive with outstanding wear resistance and durability, widely used in various linear mechanical drive systems. It is available in two standard forms: open-ended and welded endless.
Open-Ended — Ideal for linear motion and lifting/pulling applications, where its stability and precision make it the optimal solution.
Welded Endless — Produced by thermal welding process, available in virtually any length to meet diverse design requirements in precision conveying applications.
