The Bosch Rexroth CLAMPING ELEMENT (R181064251) is a hydraulic clamping unit designed for dynamic and static stabilization in the axial direction of roller rail systems. This clamping element can be utilized with all SNS roller guide rails, ensuring broad compatibility and application flexibility. It boasts a compact design that adheres to DIN standards, allowing for easy integration into various systems. The KWH 6505 BS2A model features a solid, rigid steel housing that is chemically nickel-plated, providing robustness and resistance to harsh conditions. It offers very high axial holding forces, which contribute to its effectiveness in securing components with precision. The unit is equipped with special pressure diaphragm technology that ensures maximum functional reliability without pressure losses or leakage, enhancing its operational longevity. With the ability to perform up to 1 million clamping cycles (Bd value), this clamping element promises durability and consistent performance over time. It has integrated positive-locking contact profiles that deliver maximum axial rigidity, contributing to high positioning accuracy. The hydraulic pressure for the unit can be continuously adjusted from 50 to 350 bar, giving users control over the clamping force as per their specific requirements. The device also includes an all-around sealing feature for additional protection against contaminants. For convenience, it is threaded on both sides for the hydraulic connection and supports a nominal size according to the application's demands. Its functional principle involves using hydraulic oil pressure applied through a piston principle directly onto the flanks of the Roller Guide Rail for secure clamping, while a pre-tensioned return spring ensures quick decompression cycles when necessary. This Bosch Rexroth CLAMPING ELEMENT is an essential accessory for profiled rail systems requiring reliable and precise axial stabilization through hydraulic clamping mechanisms.

Notes for mounting

Stop surfaces can be used on two sides. Make sure the connection structure is rigid. Observe the mounting instructions prior to commissioning. Check whether the sealing lips of the end seals are resting evenly on the roller guide rail. Realign if necessary.

Notes on lubrication
