Description Shipping Information Returns

The Bosch Rexroth KWD-015-FNS-C1-N-1 is a compact, high-rigidity ball runner block from the FNS series (size 15) designed for demanding linear-motion applications where strength and precision matter. Built with a carbon-steel body and factory lubrication, it offers excellent dynamic performance and long service life. 

Key Features & Benefits

  • Format FNS (Flange, Normal length, Standard height): The “F” indicates a flange width design, offering increased lateral rigidity by providing a wider base for mounting. 

  • Size 15: Ideal for systems with more compact profiles, yet requiring robustness. 

  • Carbon steel (CS) body construction: Delivers high stiffness and durability under load, ensuring long-term stability and minimal deflection. 

  • Preload class C1 (Low preload): This offers a balanced preload—enough to reduce clearance and improve rigidity without introducing excessive internal stress. 

  • Accuracy class N (Standard accuracy): Suitable for many industrial automation applications where ultra-precision is not the primary requirement but reliable guidance is essential. 

  • Pre-lubricated & factory preserved: Comes with initial lubrication and rust prevention, reducing immediate maintenance needs. 

  • High dynamic & static load capacity: For example, the dynamic load capacity is approximately 9,860 N and the static load capacity around 12,700 N for this size. 

  • High system rigidity: Features such as a patented entry zone for the balls reduce frictional oscillations and improve travel accuracy significantly. 

Typical Applications

This model is ideal for applications such as:

  • Precision automation systems where high rigidity and durability are required

  • Machine tool assemblies, CNC rigs, pick-and-place robotics

  • Retrofitting or replacement in existing linear guide systems using the FNS format or compatible rails

  • Situations where mounting stability and load capacity matter more than ultra-miniature width
