Rigidity Coupling 

  • Coupling having frequently powerful shaft-combination.
  • Having no allowable offset applies to condition in axial side absorbing angular deviation.
  • To install loch screw on coupling secures the shaft well.
  • Light, very low inertial and high sensibility
  • Maintenance free, super anti-oil and corrosion-resistance

Coupling Selection & Character Comparison


Spacer Material Comparison


Urethane (PU)

PU glue is also called polyurethane
Polyurethane application is kind of flexible polymer, used as elastic resilience and damping in shock absorber. Generally, polyurethane suits for terrains with collision from small to medium level most, and adjustable polyurethane makes perfect effect. Urethane glue is water-resistant, abrasion-resist, high mechanism strength, and product hardness adjusted by purposes, high elasticity, good shock absorbability, no hurting machine tools, an excellent anti-collision material.


Character chart for PU

Specific gravity: 1.11 ~ 1.24
Thermal distortion temperature: Softening point
Flammability: Flammable
Advantage:
  • Good abrasion-resistance
  • Climate-resistant and low temperature-resistant (-35°c ~ 50°c)
  • Anti-oxygen, ozone aging characters
  • Good tensile rate of bending strength
  • Adjustable toughness
Defect:
  • Softness in low level, easily stuck while demolding and shrink.
  • Long dried time for materials

Remark of plastic spacer corresponding to environment temperature

Plastic spacer series include rubber or plastic parts. These model must be used in operating temperature range indicated on our catalogs. If temperature over 30°c, max- torque and allowable torque shall be corrected by factors as listed below.
