R165119420 KWD-015-FNS-C0-N-1 Bosch Rexroth Ball Runner Block Carriage

The Bosch Rexroth KWD-015-FNS-C0-N-1 is a flange-base ball runner block engineered for reliable, high-rigidity linear motion. Its FNS format (flange width, normal length, standard height) gives a stable mounting base and consistent performance even under heavy or uneven loads. With size 15 and carbon-steel construction, this block is suited for demanding automation, machining, and linear-motion applications where strength, stability and smooth travel are required.

Pre-lubricated and factory-sealed, this runner block is designed for long operational life with minimal maintenance — perfect for high-duty environments and industrial systems.

Key Features

• FNS design (Flange / Normal length / Standard height) — offers a wider mounting footprint and stable rail engagement. 

• Size 15 — compact yet capable of handling significant load for its form-factor. 

• Carbon steel body (CS) — maximises rigidity, durability and resistance to deformation under load. 

• Preload Class C0 (preload-free / clearance type) — provides smooth, low-friction motion and is ideal where preload is not required. 

• Accuracy Class N (standard precision) — gives reliable repeatability and positional accuracy for general automation, CNC and linear-motion systems. 

• Standard seal (SS), ball-chain free version — reduces maintenance needs and simplifies installation while preserving sealing integrity. 

• Pre-lubricated & preserved at factory — ready for installation, suited to long-term operation with minimal maintenance intervals.

Typical Applications

The KWD-015-FNS-C0-N-1 is ideal for:

• Industrial automation and assembly machinery requiring stable, repeatable linear motion.

• CNC machines, milling, engraving or routing machines where flange mounting and robust guidance are needed.

• Pick-and-place, handling or robotic systems needing smooth, low-friction travel without preload.

• Retrofit or maintenance of existing linear guide systems that use size-15 rails.

• Applications where load capacity, rigidity and stability across multiple loading directions are more important than preload-induced stiffness.
