R162319420 KWD-015-SLS-C0-N-1 Bosch Rexroth Ball Runner Block Carriage

The Bosch Rexroth KWD-015-SLS-C0-N-1 is a long-body, slimline ball runner block designed for high-performance linear motion applications where stability, load capacity and smooth running are essential. The SLS format — slim width, long length, standard height — provides a larger contact surface for improved running accuracy and reduced deflection, while still maintaining a compact footprint for restricted transverse spaces.

Built from robust carbon steel, pre-lubricated and factory sealed, this runner block offers long service life with minimal maintenance. It is especially suitable for automation, CNC systems and precision machinery requiring high stability without the tighter preload of C1 or C2 models.

Key Features

• SLS design (Slimline / Long / Standard height) for improved stability and reduced deflection.

• Size 15 — compact yet strong, ideal for lighter machine footprints with demanding load requirements.

• Carbon steel body for maximum rigidity, strength and durability in industrial environments.

• C0 preload (no preload) providing free-running motion with minimal rolling resistance — ideal where quiet, smooth travel is preferred over stiffness.

• Accuracy class N offering dependable positioning and repeatability for most automation and mechanical applications.

• Pre-lubricated and sealed for immediate installation and long-life operation.

• Four-direction equal load rating, ensuring consistent performance regardless of rail orientation.

• Fully compatible with Bosch Rexroth SLS, SNS and SNO size-15 rails of matching accuracy class.

Technical Specifications

• Block width is 34 mm, giving a compact slimline profile suitable for narrow rail spacing.

• The block length is 72.6 mm, providing a longer bearing contact area for greater stability and smoother travel.

• Overall block height (with rail) is approximately 24 mm, while the body height alone is around 19.9 mm.

• The total block weight is approximately 0.20 kg, allowing lightweight yet robust system design.

• Dynamic load capacity is rated at around 12,800 N, delivering reliable performance under continuous motion.

• Static load rating is approximately 18,400 N, ensuring strong resistance to shock and heavy stationary loads.

• Maximum dynamic moment loads are approximately 120 Nm, providing strong resistance to torsion and uneven loading.

• Maximum linear speed is up to 5 m/s, supporting high-speed automation or long-travel systems.

• Maximum permissible acceleration is up to 500 m/s², suitable for fast-cycle machinery and rapid positioning systems.

• Operating temperature range is typically –10°C to +80°C, with short-term tolerance beyond this range depending on lubrication.

• Equipped with standard sealing, offering reliable protection against dust, coolant mist and general contamination.

• Supplied fully lubricated with factory grease, using Bosch Rexroth’s recommended lubrication channels for long service intervals.

Typical Applications

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

• CNC routers, milling or engraving machines requiring longer runner blocks for added stability.

• Automation and assembly machinery with narrow installation widths but high load demands.

• Robotics and pick-and-place systems requiring smooth, low-resistance linear movement.

• Precision-guided systems where minimal friction is more important than preload stiffness.

• Retrofit or replacement projects using existing Bosch Rexroth size-15 rails.
