The Bosch Rexroth CLAMPING ELEMENT MK 3505 AR (R181034260) is a sophisticated pneumatic clamping unit designed for use with roller rail systems. This component is engineered to provide dynamic and static stabilization in the axial direction, ensuring precise positioning for applications requiring high dynamics and powerful drive capabilities. The unit boasts an impressive service life, capable of up to 1 million clamping cycles, and features a chemically nickel-plated steel housing that provides high axial and horizontal rigidity. The clamping mechanism operates via compressed air across a dual-acting gate valve gear mechanism that presses the clamping profiles to the web surfaces of the roller guide rail. It offers continuously adjustable pressure from 2 to 6 bar, accommodating various operational requirements. The decompression process is expedited by a pre-tensioned return spring, allowing for short decompression cycles. Designed for versatility, this clamping element can be mounted easily on all SNS roller guide rails. It has an air consumption rate of approximately 2.4 liters at standard air port conditions and operates within a permissible ambient temperature range of -30°C to +80°C. The unit's nominal size corresponds with different profiled rail system sizes including H, E, A, d, N, B and S thread diameter systems. Additionally, the CLAMPING ELEMENT MK 3505 AR offers precise positioning due to its high-quality construction and design. With options for various runner block sizes and lengths, it can be tailored to specific system requirements. Its functional principle ensures that it clamps with air pressure while decompression occurs with spring force, providing both efficiency in operation and safety in release. Overall, this pneumatic clamping unit is an essential accessory for profiled rail systems requiring reliable clamping and braking functions.
