Zimmer Group Clamping element LBPS4501AS2-LP-A

Description:

The Zimmer Group LBPS4501AS2-LP-A is a pneumatic clamping and braking element designed for linear guide systems to provide secure holding, stopping, and positioning of moving axes. It uses a spring-loaded mechanism that clamps without air pressure (normally closed) and releases when compressed air is applied, ensuring fail-safe operation during power or pressure loss. The unit is built for high durability, compact installation, and precise performance in demanding automation environments.

Applications:

The Zimmer Group LBPS4501AS2-LP-A clamping element is used in linear motion systems such as CNC machinery, robotics, assembly lines, and automated production equipment. It is commonly installed on profile rail guides to hold axes in place, provide braking during motion, and ensure safe stopping in emergency or energy-loss conditions.
