Rubber Timing Belts Applications, Materials, Features, Advantages & Specifications

Applications

Rubber Timing Belts are ideal for compressors, textile, money handling, data storage, vacuum cleaners , hand power tools, centrifuges, medical diagnostic, robotics, ticket dispensers, food processors, pumps , conveyors, packaging , laundry, pulp, outdoor power equipment, printing, machine tools, postage equipment, sand, gravel, sewing machines, vending machines, agriculture, wood, office machines, paper, HVAC, oil fields and other applications.

Features/Advantages

  • Eliminates re-tensioning and lubrication, so less labor and maintenance required on drives.
  • Fiberglass tensile cord gives good flex life, high strength and high resistance to extension.
  • Neoprene body protects against moisture, grease, oil and grime.
  • Nylon tooth facing presents long service life by a durable wear surface.
  • Backing provides protection against frictional wear and environmental pollution if power is transmitted from the back of Rubber Timing Belts.
