The Bosch Rexroth B.RUNNER BLOCK AL (R163279420) is a high-precision aluminum ball runner block designed for lightweight construction and compensating low tolerances in connected structures. This slimline, normal, standard-height runner block is made from aluminum, offering reduced weight without compromising on precision. It features an optimized entry zone geometry and a high number of balls to minimize variations in elastic deflection, contributing to its excellent dynamic characteristics. The B.RUNNER BLOCK AL is prelubricated with roller bearing grease Dynalub and does not include a ball chain or attachment elements on either the left or right front reference edges. Its straight lube connection is loosely attached, allowing for easy maintenance. The product boasts a maximum permissible torsional moment (Mt max), dynamic load capacity (C), and dynamic longitudinal moment load capacity (ML), all determined in accordance with DIN ISO standards. Designed for use with all SNS ball guide rails, this runner block ensures maximum precision with its patented entry zone that can increase travel accuracy by up to six times. It supports minimum quantity lubrication with an integrated reservoir for oil lubrication and has predrilled holes for pinned fitting, enabling greater parallelism and height offsets of mounting bases. The B.RUNNER BLOCK AL is suitable for long-term lubrication over several years and can be used interchangeably within each accuracy class of H and N across all rail systems. It also accommodates a range of ambient temperatures, ensuring reliable performance under various operating conditions. With its exceptional design focusing on minimal friction due to the four rows of balls allowing point contact in all loading directions, the runner block operates with low friction coefficients. Additionally, it comes equipped with standard SS seals to prevent contaminants from entering the ball runner block while maintaining ease of movement. This product is ideal for applications requiring compact linear guides that offer high load capacity and low weight such as industrial robots and general machine building. Its unique features make it an optimal choice for designers looking to achieve maximum precision with aluminum-based motion components.
