In china we call Gr-Type PU Coupling Damping Pad
material: PU, and EPDM is available
Standard: GB5272-85
Application: Can compensate the relative deviation, damping, buffering, small radial dimension, simple structure, no need of lubrication, the bearing capacity is high, easy to maintain, but change the elastic element in two shaft coupling needs to move along the axial direction. Is suitable for connecting two coaxial, frequent starting, reversing the changes, low speed, small power transmission, high reliability requirements of shafting parts, not suitable for heavy load and axial size restrictions, parts of the two axis of difficulties in the replacement of the elastic component.
Torque: 22.4 - 2500NM
Wear: < 0.05cm3 / 1.61km
Product hardness: 95A + 5
Standard: GB5272-85
Specifications:GR19- GR75
material:According to the selection of different materials in different conditions, such as fan, water pump, light industry, textile and other stable work, little change in load, can be used polyurethane
