Timing Belts
Synchronous Belts Built for Performance and Strength
Bestorq timing belts are engineered for exacting power transmission in mechanical systems that rely on precision. Built with treated fiberglass tensile cords, high-strength nylon facing fabric, and a flexible synthetic rubber body, these belts maintain tooth integrity and eliminate slip in synchronous drives.
Precision Single-Sided, Double-Sided & Open-Ended Timing Belts
Stocked with a full range of tooth profiles, widths, and dual-sided configurations, Bestorq timing belts are in sleeve form for cut-to-width flexibility. Whether you’re working with trapezoidal, HTD, GT2, or RPP pulleys, these belts are designed to fit, perform, and last.

FAQ
You Have Questions. We Have Answers.
What are timing belts used for?
Timing belts provide precise, synchronous motion between shafts. They are used in applications where accurate timing is critical and slippage is not acceptable.
Can you cut timing belts to custom widths?
Yes. Our timing belts are stocked in sleeves and can be cut to almost any width.
Which timing belt tooth profiles do you offer?
We support trapezoidal HTD, GT2, and RPP compatible tooth profiles in both square and round shapes.
What makes fiberglass cord important in timing belts?
Fiberglass cords have low stretch and maintain their length under load, helping the belt stay synchronized during operation.
