Imperial Rubber Series Synchronous Belts

Imperial Rubber Series Synchronous Belts

With the CONTI® SYNCHROBELT and Transflex rubber belts TransDev offers TWO brands that together provide even more choice to buyers and users. Wherever the application and whatever the budget TransDev has a rubber belt to meet your exact requirements.

Imperial Timing Belts

The Imperial Timing belts utilise a trapezoidal toothform in various sizes, resulting in flexible and reliable timing belts for a wide variety of applications.

A comprehensive standard range has been developed for various load capacities and service conditions.

Compact drive design

Good strength and flexibility allows the use of small pulley diameters, small centre distances and reverse bending idlers. High quality pulleys with pilot bored or taper lock design enable a low-cost, readily available drive setup.

High efficiency

The superb flexural properties of the synchronous drive belt as well as the exact dimensional mating of the belt and pulley tooth contours permit drives with an efficiency of 98%.

Polychloroprene teeth and backing

The teeth and the belt top are made from high strength Polychloroprene based elastomer materials. A special manufacturing process ensures an excellent adhesion both on tensile member and on the facing fabric.

Glass fibre tension member

Timing belt drives call for a high degree of length stability and tensile strength. The Imperial belts have a low-elongation tensile member of Glass cord, helically wound in opposing pairs over the entire belt width.

Polyamide fabric&lt

Durable teeth protection is provided with an abrasion-resistant Polyamide fabric with a low coefficient of friction.

Imperial rubber belts are resistant to

  • Oil, to a degree
  • Tropics
  • UV and ozone
  • Temperatures ranging from -20°C to +100°C
