R162289422 Bosch Rexroth - Linear Runner Block KWD-020-SNS-C0-N-1

R162289422 Bosch Rexroth KWD-020-SNS-C0-N-1 - Linear Ball Guide Runner Block Size 20

R162289422 Bosch Rexroth is a linear ball guide runner block with the designation KWD-020-SNS-C0-N-1, designed for precise linear motion in industrial machinery and equipment. It belongs to the Bosch Rexroth profiled ball rail guide system and has a nominal size of 20 mm. The runner block features a narrow SNS design, standard height, normal length, C0 preload class and N accuracy class.

The product uses recirculating rolling elements to provide smooth linear movement along a compatible guide rail. Its ball chain design reduces direct contact between adjacent balls.

Technical Specifications - R162289422 Bosch Rexroth

The 30 mm height refers to the complete runner block assembly with a compatible guide rail. The runner block itself has a catalog height of 25.35 mm.

What Do R162289422 and KWD-020-SNS-C0-N-1 Mean?

R162289422 - Bosch Rexroth Material Number

R162289422 is the manufacturer's material number identifying a specific Bosch Rexroth linear guide runner block configuration.

The complete material number is important when ordering a replacement because runner blocks of the same nominal size may differ in accuracy class, preload, sealing arrangement and construction.

KWD-020 - Size 20 Ball Runner Block

KWD identifies the ball runner block design.

The number 020 specifies the nominal size of the linear guide system.

It does not indicate the actual runner block width.

For this version, the runner block width is 44 mm.

SNS - Slimline, Normal Length, Standard Height

SNS identifies the runner block configuration:

• S - Slimline design.

• N - Normal length.

• S - Standard height.

The SNS construction is suitable for linear motion systems where installation space is limited while appropriate guidance and load-carrying characteristics must be maintained.

C0 - Without Preload

C0 indicates a runner block version without preload.

This designation should not be confused with the basic static load rating C0, as these are two different technical parameters.

The preload class affects running characteristics, stiffness and installation requirements.

N - Normal Accuracy Class

The letter N identifies the normal accuracy class.

For applications requiring higher positioning accuracy, the machine manufacturer's requirements and the available precision classes should be verified.

SS - Standard Sealing

The runner block is equipped with standard sealing elements.

Their purpose is to reduce the entry of contaminants into the ball circulation system and help retain lubricant.

Additional protection may be necessary in environments exposed to heavy dust, chips or coolants.

Dimensions of Bosch Rexroth R162289422

The principal installation dimensions are:

All dimensions should be interpreted according to the manufacturer's technical drawing.

When replacing a runner block, the assembly height, mounting hole spacing and installation arrangement are just as important as its overall width and length.

Basic Dynamic and Static Load Ratings

Basic Dynamic Load Rating C - 23.4 kN

The basic dynamic load rating is:

C = 23,400 N

This parameter is used to calculate the nominal service life of the linear guide under specified loading and movement conditions.

Basic Static Load Rating C0 - 29.8 kN

The basic static load rating is:

C0 = 29,800 N

This parameter is used to assess loading conditions that may cause permanent deformation at the contact areas between the balls and raceways.

The C and C0 ratings do not represent universally permissible operating loads.

Correct selection must also account for applied moments, load distribution between runner blocks, motion dynamics and required service life.

Ball Chain - Recirculating Ball Design

The R162289422 runner block features a ball circulation system with separating elements.

This design:

• Reduces direct contact between adjacent balls.

• Supports consistent ball circulation.

• Can contribute to smoother and quieter movement.

• Works together with the runner block lubrication system.

Actual noise levels and running resistance also depend on installation accuracy, lubrication and applied loads.

Compatibility with Bosch Rexroth Guide Rails

The runner block is designed to operate with compatible Bosch Rexroth profiled ball guide rails in nominal size 20.

Product catalog listings indicate compatibility with suitable rails from the R1605 and R1607 series.

Compatibility must be confirmed using the complete guide rail designation.

Nominal size 20 alone does not guarantee compatibility with every linear guide system.

A replacement should not be selected solely on the basis of similar dimensions from another manufacturer.

Lubrication and Maintenance

The runner block requires suitable lubrication according to Bosch Rexroth specifications.

Commercial technical documentation for this version identifies Dynalub 510 grease.

During operation:

• Use an appropriate lubricant.

• Follow the required relubrication intervals.

• Protect the guide rail raceways against contamination.

• Inspect the condition of the seals.

• Avoid operation with insufficient lubrication.

• Inspect the guide rail and runner block during scheduled maintenance.

Relubrication intervals depend on loading, speed, stroke length, temperature and environmental conditions.

Applications of Bosch Rexroth R162289422

The runner block may be used in appropriately designed linear motion systems such as:

• CNC machinery.

• Industrial automation equipment.

• Production lines.

• Packaging machinery.

• Positioning systems.

• Assembly equipment.

• Machine linear axes.

• Material handling systems.

• Measuring equipment.

• Special-purpose machinery.

These are typical application areas for profiled ball rail guides, not verified fitments for specific machine models.

How to Select a Replacement for R162289422

Before ordering, verify:

1. Material number R162289422.

2. Complete designation KWD-020-SNS-C0-N-1.

3. Bosch Rexroth manufacturer identification.

4. Nominal size 20 mm.

5. SNS configuration.

6. Runner block width of 44 mm.

7. Runner block length of 75 mm.

8. Assembly height with rail of 30 mm.

9. Mounting hole spacing.

10. C0 preload class.

11. N accuracy class.

12. Standard SS sealing.

13. Ball chain design.

14. Dynamic and static load ratings.

15. Complete designation of the compatible guide rail.

A runner block with identical dimensions but a different preload or accuracy class may not be a suitable replacement.

Installation of the Linear Guide Runner Block

During installation:

• Clean the reference and mounting surfaces.

• Inspect the condition of the guide rail.

• Verify runner block and rail compatibility.

• Use appropriate mounting components.

• Follow the specified tightening torques.

• Prevent balls from escaping when handling the runner block.

• Provide correct lubrication.

• Check the smoothness of movement after installation.

Incorrect alignment of guide rails or mounting surfaces may cause additional stresses, increased running resistance and premature guide wear.
