High Torque Drive Industrial Belt

HTD High Torque Drive Belts – 3M, 5M, 8M, 14M, 20M

High-Performance Synchronous Belts for Precision Industrial Power Transmission

HTD (High Torque Drive) belts are engineered for superior torque capacity, smooth operation, and long-term durability in synchronous drive systems. Unlike classical trapezoidal timing belts, HTD belts feature a curvilinear tooth profile that provides uniform load distribution, reduced tooth stress, and improved power transmission efficiency. This design minimizes slippage and wear, making HTD belts ideal for high-speed, high-torque, and precision-driven applications.

Constructed from high-strength neoprene or polyurethane with fiberglass or aramid tensile cords, HTD belts offer excellent resistance to stretching, abrasion, heat, and chemical exposure—ensuring long operational life in demanding industrial environments.
