The Bosch Rexroth CLAMPING ELEMENT HK 2505 KB (R161924283) is a high-quality manual clamping unit designed for use with ball rail systems. This robust clamping element is versatile and can be applied to all SNS ball guide rails, providing a simple and secure solution in a compact design. It operates manually, eliminating the need for auxiliary power and allowing for precise positioning through its freely adjustable hand lever. The clamping unit excels in symmetrical force application on the ball guide rail via floating contact profiles, ensuring reliable holding forces of up to N. The HK 2505 KB is also compatible with all BNS roller guide rails, showcasing its adaptability across different guide systems. Its design includes features that cater to various profiled rail systems including size H, size E, size A, size N, size L, and size B. For each of these sizes, it ensures maximum holding force while maintaining the integrity of the runner block's height. Built for durability and consistent performance, this clamping element can withstand a permissible ambient temperature range from C to C. The inspection standard adheres to an ISOVG lubricated layer condition ensuring optimal operation. Additionally, it offers ease of installation with its straightforward tightening torque specifications and is available in various lengths and widths to match the runner blocks of different profiled rail systems. The functional principle behind this unit is based on manual pressure applied through the hand lever which presses the clamping profiles onto the web surfaces of the Ball Guide Rail. This manual activation allows for quick engagement and disengagement without compromising on the holding strength or precision. Overall, the Bosch Rexroth CLAMPING ELEMENT HK 2505 KB presents itself as an essential accessory for profiled rail systems that require reliable manual clamping capabilities without relying on external power sources. Its compatibility with multiple rail sizes and its robust construction make it an ideal choice for securing components in a variety of linear motion applications.
