Timing Belts Metric & Imperial and PU

Timing Belts Metric & Imperial and PU

Timing belts are avaiable at Bearing King in single or double sided version, in classical pitches and RPP profiles

Timing belts, also known as synchronous belts, are essential for applications that demand precise and consistent power transmission. At Bearing King, we supply a complete range of timing belts—both metric timing belts and imperial timing belts—to suit light-, medium-, and heavy-duty industrial and mechanical systems. These belts are available in both single-sided and double-sided versions, in classical pitch and RPP profiles, giving you total flexibility for any drive configuration.

Why Timing Belts Matter

Unlike traditional V-belts or flat belts, timing belts are engineered with accurately moulded teeth on the inner surface that mesh perfectly with pulley grooves. This eliminates slippage, ensuring the drive operates in complete synchronisation. The result is highly efficient, vibration-free performance that provides a fixed speed ratio and precise movement of drive components. Because there is no relative motion between the belt and pulley, speed variation is virtually eliminated—an essential factor in precision manufacturing and automation systems.

Construction and Performance

A timing belt typically features a high-strength tensile cord made of fibreglass, aramid, or steel, positioned at the belt’s neutral axis. This cord provides exceptional tensile strength while minimising stretch, reducing the need for re-tensioning or frequent maintenance. The belt body is made from synthetic rubber or polyurethane, ensuring excellent resistance to oil, abrasion, and temperature extremes (from −25 °C to +80 °C).

The toothed design of the timing belt not only guarantees positive engagement but also allows high torque transmission at low tension levels. This makes the system quieter, lighter, and more efficient than conventional chain or gear drives—ideal for modern industrial and automotive applications.

Applications and Advantages

Timing belts are used across a wide spectrum of industries, from office automation and printing machinery to heavy-duty conveyors and crushing equipment. They offer several key advantages:

  • Fixed speed ratio for synchronised motion

  • No slippage or loss of torque

  • Minimal maintenance and long service life

  • High efficiency across a broad speed range

  • Quiet operation compared to chain drives

  • Simple timing belt replacement without complex alignment adjustments

Whether you require a metric timing belt for precision equipment or an imperial timing belt for legacy machinery, Bearing King can provide the correct profile and pitch to match your requirements.

Belt Profiles and Product Range

We offer three main tooth profiles to suit different torque and precision needs:

  • Classical Timing Belts – Trapezoidal tooth profile for light- to medium-duty applications requiring positional accuracy.

  • HTD (High Torque Drive) Belts – Curvilinear tooth design for high-torque transmission with reduced stress concentration.

  • STD (Super Torque Drive) Belts – Modified curvilinear profile for high torque with accurate indexing.

Our product collections include:

Each option is manufactured to the highest standards, ensuring precise performance, long operational life, and consistent reliability under varying loads and conditions.
