UIC 630 010 4127 Flexible Disc Encoder Linear Ball Screw Coupling

Description:

The UIC  630 010 4127 Flexible Disc Encoder Linear Ball Screw Coupling is used in precision motion control systems to transmit torque while compensating for shaft misalignment between an encoder and a ball screw assembly. Commonly installed in Universal Instruments SMT pick-and-place machines, CNC machinery, linear actuators, and industrial automation equipment requiring accurate encoder feedback and backlash-free power transmission. Maintenance teams, OEMs, and system integrators use this coupling for replacement, retrofit, and repair projects to restore machine accuracy and maintain reliable motion control. 

Applications:

The UIC  630 010 4127 Flexible Disc Encoder Linear Ball Screw Coupling is used to connect rotary encoders to ball screws or servo motors in precision automation equipment. It is commonly found in PCB assembly systems, semiconductor equipment, CNC machines, and linear motion systems where torsional rigidity and low backlash are essential for maintaining positioning accuracy. Flexible disc couplings are designed to accommodate angular, parallel, and axial shaft misalignment while minimizing wear on connected components.
