3.175mm to 5mm Coupling for CNC Machines

A Coupling is a device used to connect two shafts to transmit power. Typically, couplings prevent the shafts from separating during operation, although torque-limiting couplings can slip or disconnect when the torque exceeds a certain threshold.

The primary purpose of a coupling is to connect two rotating components while allowing for slight misalignments. Proper selection, installation, and maintenance of couplings can lead to significant savings in maintenance costs and reduce downtime.

This Brass Motor Coupling with a bore size ranging from 3.17mm to 5mm is ideal for CNC machines. It can be used in spindle motors, CNC routers, and CNC engravers, providing reliable power transmission and alignment between shafts.

A high-quality 5mm Coupling ensures durability and smooth operation in precision machining applications.
