The timing belt adopts special RPP tooth shape, which is accurate in transmission ratio and high in efficiency.Choose polyurethane bottom belt, high wear resistance and tear resistance, surface added wear-resistant neoprene, increase friction, not easy to wear, the middle layer of high strength steel wire core for the strong layer, tensile strength increased by 35%, not easy to stretch.For each application there is a suitable coating to achieve a desired coefficient of friction, abrasion resistance, or thickness.All backings can be modified mechanically on request. yonghangbelt specially customizes belts according to your requirements like vacuum chambers, grooves, slots, perforations etc.
HTD 3M 5M 8M 14M 20M Timing belt，This section provides detailed information about all types of HTD timing belts materials, shape profiles, load capacity, working temperature, hardness, etc.
RPP2M 3M 5M 8M 14M Low noise PU timing belt is a modified tooth shape on STD timing belt series, the purpose is to reduce the surface contact in the middle of the tooth shape to achieve the effect of noise reduction. The specifications of RPP2M 3M 5M 8M 14M Low noise PU timing belts can be customized according to your needs.
Customized Truly Endless Polyurethane Timing belts for Hoop bending machine PU seamless timing belt are made of high-strength polymers and reinforced materials, which make them mechanicalforth of all industrial applications. We can help you optimize your design and recommend the right solution, including custom-made polyurethane syncs trips and surfaces plus PU/holes /rubber/sponge/baffle/cleats, etc
Electric curtain lifting timing track belt Polyurethane Open-Ended Timing Belts Electric curtain lifting timing track belt they are manufactured with the teeth and bottom from thermoplastic polyurethane with excellent wear resistance and with high tensile strength steel tension member, in special cases with kevlar or stainless steel tension member. The open-ended belts can be welded into endless belts.
The Yonghangbelt is a PU flat belt, which is manufactured in open lengths and can be continuously welded. All tension members are arranged parallel to the edges of the belt, however in the join area, only half of the tension members assume part of the load.Its applications include lifting tables, lift systems, car washes or similar. This PU flat belt is available in belt widths 15mm，25 mm, 32 mm, 50 mm, 75 mm and 100 mm. Thickness 1-4mm .It is either supplied with steel or stainless steel tension member. The belt backing and running side are both made of polyurethane.
Understanding Curvilinear Tooth Profiles: HTD vs. STD vs. RPP
Curvilinear (curved) tooth timing belts were developed to overcome the torque limitations of classic trapezoidal profiles by distributing stress more evenly across the tooth engagement zone:
HTD Profile (High-Torque Drive): Featuring a deep, rounded curvilinear tooth geometry, HTD belts (3M, 5M, 8M, 14M) offer exceptional resistance to tooth shear and jumping under heavy torque loads. They are widely specified in robotics, industrial automation, and heavy packaging machinery.
STD Profile (Super Torque Drive): Engineered with a flattened tooth crest (S3M, S5M, S8M, S14M), STD profiles ensure smooth, ultra-quiet tooth engagement with minimal backlash. Ideal for high-speed indexing, linear modules, and medical automated machinery.
RPP Profile (Reinforced Parabolic Profile): Designed with a parabolic tooth contour and a distinctive groove on the tooth top (RPP3, RPP5, RPP8, RPP14). This profile enhances flexibility, reduces stress concentration at the tooth root, and provides high efficiency in demanding power transmission drives.
