FAQ What type of rail is compatible with the KWD-035-SKS-C0-N-1 runner block?This runner block is designed for use with Rexroth Ball Guide Rails of size 35. It is crucial to match the runner block size with the corresponding rail size for proper function and accuracy. What does the preload class ‘C0′ mean for this runner block’s application?C0 signifies zero preload. This means there is no internal force applied between the balls and the raceways when the block is mounted. It is suitable for applications where very low friction and smooth movement are prioritized over maximum rigidity. How should this runner block be lubricated for optimal performance and lifespan?This runner block is typically delivered with initial preservation oil. For operation, it must be lubricated using a grease or oil compatible with linear guide systems, such as those specified in the Rexroth catalog (e.g., Dynalub 510). Regular re-lubrication intervals depend on the application’s load, speed, and environmental conditions.
