FAQ What type of rail is this R201189330 runner block compatible with?This KWD-020-SNS-C0-H-1 block is designed for use with Bosch Rexroth size 20 ball guide rails. It is crucial to match the runner block size to the rail size for proper function and accuracy. What does the ‘C0’ preload class signify for this component?The ‘C0′ preload class indicates zero preload. This means there is no internal force applied between the balls and the raceways when the block is mounted. This configuration is ideal for applications requiring very low friction and smooth movement, at the cost of slightly lower rigidity compared to preloaded blocks. How should this ball runner block be lubricated upon installation?Rexroth runner blocks are typically shipped with an initial preservation oil. For long-term operation, it must be lubricated according to the application’s speed, load, and environmental conditions. Use a high-quality lithium-based grease or a suitable oil compatible with linear motion systems. Refer to the Bosch Rexroth documentation for specific lubricant recommendations and maintenance intervals. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
