The Bosch Rexroth FRONT SEAL (R161982120) is a crucial component designed for enhancing the performance and longevity of ball rail systems. This front seal is specifically tailored for use with various sizes of Bosch Rexroth's profiled rail systems, including Size H, Size B, and Size E, as well as the diameter S profiled rail systems. Constructed from corrosion-resistant steel in accordance with DIN EN standards, it features a bright, two-piece design with a plastic seal ring that ensures a secure fit and optimal protection against contaminants. The product's robust design makes it suitable for a wide range of applications where linear motion is required, providing a reliable sealing solution that helps maintain the integrity and precision of the rail system. The FRONT SEAL is part of Bosch Rexroth's accessories for profiled rail systems and plays a vital role in preventing the ingress of dust and debris which can affect the system's performance. It should be noted that this front seal is not compatible with certain ball runner blocks, specifically those designated as F.N flange ... low and S.N. Slimline ... low. The nominal size and lightweight construction make it an unobtrusive yet essential addition to any compatible linear guide setup. As an accessory designed to complement Bosch Rexroth's range of profiled rail systems, the FRONT SEAL (R161982120) ensures that users can maintain optimal functionality of their linear guides while extending their service life through enhanced protection. It stands out as a testament to Bosch Rexroth’s commitment to providing high-quality components that meet stringent industry standards for durability and performance.
