Bosch Rexroth R165321320

The Bosch Rexroth Ball Runner Block FLS Size 25 is engineered for applications demanding the highest levels of precision and rigidity. Featuring a robust runner block body made of unalloyed steel, this ball runner block offers high accuracy and low preload (C1 class). It is designed without a ball chain and comes pre-lubricated with Dynalub 510, ensuring long-term lubrication and preservation.

With a standard height and a flange width, the runner block is highly versatile and can be combined with any guide rail, maintaining accuracy across all configurations. The patented entry zone significantly enhances travel accuracy, while the integrated all-round sealing ensures maximum protection against contaminants.

Key benefits include reduced frictional oscillations, low friction force under external loads, and excellent dynamic characteristics. The ball runner block supports high torque load capacity and offers improved rigidity under lift-off and side loading conditions, thanks to additional mounting screw holes at the center.

Applications include environments with demanding rigidity requirements, where maximum precision and dynamic performance are critical. The runner block is compatible with all SNS/SNO ball guide rails and can be used in various industrial automation and machinery applications.
