Options

  • Truly Endless (Flex/Moulded) – BFX – Power Transmission
  • Spliced and Welded – V – Conveyor
  • Open Ended – M – Linear
  • Pin Join
  • Steel + (PAZ, PAR, PAZ/PAR)

Tensile Members

  • Steel
  • Aramid Kevlar
  • Stainless steel

Materials

Self Tracking Timing Belts combine steel reinforcement with welded or moulded V guides. It provide accuracy and linear drive. Self-tracking timing belts are made with two materials:

  • Wear resistant polyurethane
  • High tensile steel cord tension members.
  • Polyamide fabric
  • Synthetic pu teeth

Advantages

– Continuous tooth engagement
– Friction reduced tracking
– Smooth idler interaction
– Smooth meshing of belt and pulleys
– Increased power range
– Improved repeatability
– Self-tracking, no flanges necessary
– Decreased polygonal effect
– More compact design
– Tangential belt drive possible
– Reduced vibration
– Reduced noise
– No lateral movement
