Flexible Coupling BC3-II

Flexible Coupling BC3-II
Flexible Coupling BC3-II

BC3 Series II Clamp Type Parallel Pattern Coupling (Flexible 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. 

Features: 
· One-piece metallic spring coupling 
· Zero backlash 
· Absorption of parallel, angular misalignments and shaft end-play by spring action 
· Identical clockwise and anticlockwise rotational characteristics 
· Clamp type 
· Material: Aluminum alloy
