Zero-backlash spring engaged brake family for power transmission

The release of the Zero-Backlash Spring Engaged (ZSE) brake family has been announced by Nexen Group. The pneumatically-released ZSE offers high torque, high speed, and zero backlash suitable for holding applications. Unlike brakes using leaf springs to transmit torque, the ZSE is zero-backlash up to 100% of its rated holding torque.

Nexen has released four different sizes (450, 600, 800, 1000) for a wide variety of applications. The bore sizes are available in three standard sizes, and can be easily customised for customer needs.

In addition, Nexen offers an option to configure the ZSE with a smart feature. The ZSES brakes are available with internal sensors, making them suitable for Industry 4.0 compatibility. These sensors provide feedback and data to maximise machine safety and efficiency.

Highlights of the ZSE Brake include:

  • Speeds up to 5000RPM
  • Zero-Backlash up to 100% of rated holding torque
  • Holding torque up to 300Nm
  • Zero-Backlash integral clamp collar
  • Low inertia
  • Customisable to wide range of shaft diameters
  • Cool operation
  • Compact housing
  • Optional Smart feature for Industry 4.0 Compatibility.
