The Bosch Rexroth B.RUNNER BLOCK CR KWD-035-SNH-C1-H-1 (R162131370) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance, high rigidity, and precision. This model features a Resist CR coating that enhances its durability and resistance to corrosion. The SNH size format indicates a slimline width, standard length, and high height configuration of the runner block body, which is made of unalloyed steel CS with a matte silver finish and hard chrome plating. The runner block boasts a low preload (preload class C) and high accuracy (accuracy class H), ensuring smooth motion with minimal frictional oscillations even under external load. It comes without a ball chain but includes initial lubrication and preservation for longevity. Its roller bearing grease Dynalub extends the period between maintenance intervals. This product has an overall length of . mm and offers interchangeability with guide rails across various accuracy classes. It is suitable for applications where space is limited in the transverse direction yet demands high rigidity. The patented entry zone significantly improves travel accuracy, potentially up to six times better than conventional designs. Notably, this runner block can sustain high load ratings from all four main directions due to its robust design. It also features end-face fastening threads for attachments and comes prelubricated from the factory for immediate use. Furthermore, it can operate within an ambient temperature range of min ... max °C for short periods; however, consultation is recommended for use at negative temperatures. The dynamic load capacity C and other load capacities are determined according to DIN ISO standards based on a 100 km travel distance. The product's friction coefficient ranges between , ... , without seal friction considered. This ball rail system component integrates seamlessly into Size E profiled rail systems and ensures optimal performance in various industrial applications.
