R155231063 Bosch Rexroth: Precision Linear Motion
The R155231063 is a high-precision Ball Runner Block from Bosch Rexroth’s renowned linear motion technology division. Specifically, it belongs to the FNS series (Flanged, Normal, Standard Height), designed for Size 35 rail systems. This component is the moving carriage in a linear guide assembly, essential for CNC machines, automated handling systems, and robotics where smooth, low-friction movement under heavy load is required. The «Ball» design utilizes recirculating steel balls to minimize friction, allowing for high travel speeds and precise positioning accuracy.

Maintenance & Lifecycle for Engineers
Lifecycle State: Active. This is a core component of the Rexroth Ball Rail System. Diagnosis: Linear guides fail primarily due to lubrication starvation or contamination. If the runner block exhibits «stick-slip» motion or excessive noise, check the lubrication nipples. The R155231063 features integral lubrication ports for grease or oil. Installation Tips: Ensure the rail and block are matched in size (Size 35). When mounting the flanged block, tighten the bolts to the specified torque in a cross pattern to prevent deformation of the carriage body. Compatibility: Fully interchangeable with all Rexroth Size 35 Ball Guide Rails. It can be integrated into automated lubrication systems controlled by Siemens SIMATIC PLCs to ensure dosing intervals are met based on travel distance.

Why choose Bosch Rexroth FNS?
The FNS design provides a wide mounting surface (flange) which offers superior torsional rigidity compared to slim-line blocks, making it ideal for single-rail applications carrying offset loads.
