NEXEN’s ball screw/stage brake is a high-torque, spring-engaged, air-released brake acting on the non-driven end of a ball screw.
It serves as a redundant safety brake in the event of a mechanical failure in the drive line, particularly in Z-axis applications.
This zero backlash brake and coupling provide a high degree of accuracy for holding the position of precision ball screws in power-off situations.
A clamp ring coupling connects the brake shaft to the end of the ball screw.
The Nexen ball screw/stage brake is spring engaged, air released and has low inertia.
It has high torsional rigidity; bi-directional braking; fast engagement and meets IP67 dust and waterproof standards.
The brake operates in vertical and horizontal applications and allows thermal expansion of the ball screw. Nexen’s ball screw/stage brake suits many applications including gantry systems, machine tools, CNC machining centres, woodworking machines, servo and DC motor drives, automation equipment, and robotics.
