1. fast release can disengage，
2. GR：with slider bearings nmax＝1000min-1 ，but with big torque force.
HR：with needle bearing nmax＝4000min-1 but wiht less torque force .
3. The maximum rotation angle for each section is 45°
4. The applied fast locking device (d2) tolerance is a finished hole belt with of H7
5. Optional keyway or hex hole standard according to DIN 6885/1-JS9
Various general mechanical occasions ，such as Power motor, Steel rolling machinery, leveling machinery, auto industry, automation equipment
How to choose a suitable coupling：
If you have different hole and size from the size chat ,we also can make same as customer’s requirement ,such as parallel pins,keyway、hexagon hole square hole。
1. Based on mechanical requirements ,such as transmission torque, stiffness requirements, vibration, impact, acid and alkali corrosion resistance, transmission accuracy .
2. If have different torque and hole,pls offer design mapping and sample ,with accept customize, no matter is fast release or with flange or needle bearing type.
3. The universal coupling is widely used in all kinds of general mechanical because of its large deviation angle and high transmission torque.
4. Coupling usually have those type : universal type, high speed type, micro type, extension type, large torque universal coupling etc.
