Curved Jaw Coupling BC7-I
Curved Jaw Coupling BC7-I
BC7 Series I Setscrew Type Curved Jaw Coupling
Coupling is the mechanical drive which is mainly used for connecting shaft and shaft (sometimes coupling spindle other rotary parts) with the transfer motion and torque, and also it is the commonly used components used for safety devices. Mechanical running can't be separated from two axis; Only be seperated in the mechanical parking and coupling apart from two axis.
Feature
· Coupling assembled by pressing a polyurethane sleeve into hubs on both sides
· Can absorb the vibration, parallel, angular misalignments and shaft end-play
· Resistance to oil and electrical insulation
· Identical clockwise and anticlockwise rotational characteristics
· Two different hardness sleeves are available
· Setscrew type
· Material: Aluminum alloy
