Spider coupling is a flexible shaft coupling,Widely used in gear pump, compressor, generator set. Elastic parts are made of engineering plastics with excellent elasticity and wear resistance.

Operation Temperature: -35~80℃。
Shaft hole range: 6~180mm

Feature

  • Compensate for parallel, angular and axial displacements.
  • Radial dimension small, simple structure, no need of lubrication.
  • For frequent startup，Drive torque:20~25000N.m.
  • Elastic parts long service life of ,great bearing capacity.
  • Usually used for gear asphalt pump,fan,mining,chemical industry.
