Product Announcement from Nexen Group, Inc.
Nexen's ball screw/stage brake is a high-torque, spring engaged, air released brake that acts on the non-driven end of a ball screw. The ball screw brake serves as a redundant safety brake in the event of a mechanical defect 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.
- Zero backlash for precision holding
- Spring engaged, air released
- Low inertia
- High torsional rigidity
- Bi-directional braking
- Fast engagement
- Meets IP67 dust and waterproof standards
- Operates vertical and horizontal applications
- Allows thermal expansion of ball screw
The multi-axis stage is capable of rotary motion, ball screws exhibit lower friction resulting in a higher efficiency, and ball screws have a predictable service life and low wear rate.
Nexen Group, Inc is a leading manufacturer of precision motion control solutions including linear drive systems, precision rotary indexers, linear locking components and power transmission products including spring set brakes, tooth clutches and torque limiters for a wide variety of automation applications in the Aerospace, Robotics, Machine Tool, Automotive, Packaging, Material Handling and Medical Industries.
