Nexen Group Inc. has announced the Zero-Backlash Spring Engaged (ZSE) brake family. The pneumatically-released ZSE offers high torque, high speed, and zero backlash ideal 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 customized 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 ideal for Industry 4.0 compatibility. These sensors provide feedback and data to maximize machine safety and efficiency.
