Collection: Timing Belts Metric & Imperial and PU

Timing / Synchronous Belts

Timing Belts or Synchronous Belts are meant for precision. They are lighter, less expensive and operate more quietly. Timing Belts are synthetic rubber strap that contains cords for strength. It has teeth moulded onto its inner surface to prevent slipping, which fits into the pulley pulley grooves. Timing Belt drive is not considered as a substitute or a replacement to other modes of belt drives.

These Belts exhibit important properties such as fixed speed ratio, no re-tensioning after installation, low maintenance with wide variety of power transmission capacities and drive speeds.

Timing Belts use teeth that mesh with grooves in a pulley to drive the system in synchronous manner. There is no slippage, which will cause speed Variations, allowing drives to be timed very accurately. The tensile cord has minimal stretch, so the constant need for take-up adjustmnent is eliminated.

Timing drives work over a very wide range of speed and torques. Torque range varies from very light duty office equipment to heavy duty crushing equipment up to several hundred kW.

Timing Belts enables it to be used in positive drive resulting in precise movement of drive components.

They are offered in three different teeth profiles
Classical Timing Belts
High Torque Drive (HTD) Belts
Super Torque Drive (STD) Belts

The Classical Timing Belt has trapezoidal teeth profile, HTD has curvilinear or spherical teeth profile and STD has modified curvilinear teeth profile.

Due to difference in teeth profiles as well as in their torque transmitting capability, these belts cannot be interchanged.

HTD Timing Belts are used in application where high torque is to be transmitted from one shaft to another and classical timing belts for precise displacement with relatively light duty application.

STD profile is used in application where high torque is to be transmitted with precision indexing.

Temperature range -25 to +80 degrees
