R030101400 REXROTH - Ball Runner Block for Linear Guideways

Product Description

R030101400 REXROTH is a linear guide ball runner block manufactured by Bosch Rexroth, identified by manufacturer material number R030101400. According to available distributor information, the product belongs to the KWD-025-SKS family, nominal size 25. The runner block operates on a compatible profiled guide rail, providing precise linear guidance through recirculating ball elements.

Unlike a conventional deep groove ball bearing, the REXROTH R030101400 runner block is not designed to support a rotating shaft. Its primary function is to guide a moving machine component along a defined linear path while transmitting loads between the carriage and the guide rail.

The exact configuration of R030101400, including mounting dimensions and rail compatibility, should be confirmed against Bosch Rexroth documentation.

Technical Specifications - REXROTH R030101400

Unverified carriage dimensions, including length, width and height, have not been included.

Dynamic and static load ratings, permissible moments, exact weight, sealing materials and lubricant specifications have also been omitted because they have not been reliably confirmed for this exact manufacturer part number.

For linear guide systems, load ratings, permissible moments and mounting geometry depend on the specific runner block configuration. Specifications from other variants in the same product family should not be assigned to R030101400 without verification.

What Does R030101400 REXROTH Mean?

R030101400 is a Bosch Rexroth material number identifying a specific product.

Unlike standardized rolling bearing designations, its individual digits should not be interpreted as dimensions or technical characteristics without the manufacturer's coding documentation.

Distributor catalogues also associate this article with the designation:

KWD-025-SKS-C0-N-1

The individual elements indicate:

• KWD - Ball runner block product family.

• 025 - Nominal size 25.

• SKS - Slimline, short runner block with standard height.

• C0 - Preload class C0.

• N - Normal accuracy class.

• 1 - Additional manufacturer configuration code whose exact meaning should be verified for this product version.

The designation C0 in Bosch Rexroth linear guide systems refers to a preload classification. It should not be confused with the basic static load rating C0 used in rolling bearing calculations.

Available distributor information does not consistently describe the exact preload characteristics of this article. Therefore, no numerical preload force has been assigned without manufacturer confirmation.

Construction and Operating Principle

The REXROTH R030101400 ball runner block is a component of a profiled rail linear guidance system.

The principal functional elements of this type of runner block include the carriage body, ball raceways, rolling elements and ball recirculation system.

Runner Block Body

The runner block body supports the moving machine component and transfers applied loads to the guide rail.

Its mounting surfaces must be compatible with the machine structure and the required installation geometry.

Rolling Elements

Balls roll along the raceways between the runner block and the profiled guide rail.

In a recirculating ball design, the rolling elements return through internal channels, allowing repeated movement along the guide rail.

Load Transmission

Profiled rail ball runner blocks are designed to transmit loads occurring during linear motion.

In addition to direct forces, the carriage may be subjected to moments caused by the position of the load relative to the guide rail.

Permissible forces and moments must be verified for the exact R030101400 configuration.

Guide Rail Compatibility

The runner block does not form a complete linear guidance system without a suitable guide rail.

Compatibility depends on the rail profile, raceway geometry, nominal size and specific manufacturer configuration.

REXROTH R030101400 vs Other Linear Guide Variants

Bosch Rexroth manufactures different runner block configurations that may vary in length, width, height, accuracy class and preload.

A runner block with the same nominal size 25 is not necessarily interchangeable with R030101400.

Differences in guide rail geometry, mounting hole spacing, installation height and preload may prevent direct replacement.

R030101400 should not be considered equivalent to another Bosch Rexroth material number simply because both products belong to the KWD-025-SKS family.

Alternative Designations and Search References

The product may be identified using the following natural designation variants:

The extended designation KWD-025-SKS-C0-N-1 is associated with R030101400 in distributor catalogues. Its complete correspondence with the supplied product should be verified using the original manufacturer label or documentation.

No unverified OEM part numbers or cross-references from other manufacturers have been assigned.

Selection and Interchangeability of REXROTH R030101400

Before purchasing R030101400, verify the following requirements:

1. Manufacturer material number: R030101400.

2. Manufacturer: Bosch Rexroth.

3. Linear guide family: compatibility with the required guide system.

4. Nominal size: 25.

5. Runner block dimensions: length, width and height.

6. Mounting hole spacing: compatibility with the machine structure.

7. Guide rail profile: correct raceway geometry and rail configuration.

8. Accuracy class: appropriate for the machine requirements.

9. Preload class: suitable for the operating conditions.

10. Load ratings and permissible moments: confirmed for the exact product configuration.

11. Lubrication requirements: according to the manufacturer's instructions.

12. Operating environment: contamination, humidity and temperature.

Identical nominal sizes do not automatically guarantee runner block interchangeability.

When replacing a worn component, the most reliable identification method is to compare the complete Bosch Rexroth material number.

Typical Applications

Profiled rail ball runner blocks are used in systems requiring controlled linear movement.

Typical applications of this type of linear guidance system include:

• Automated assembly equipment.

• Industrial linear positioning systems.

• Manufacturing machinery.

• Linear transfer and handling mechanisms.

• Measuring and inspection equipment.

• Industrial automation systems.

• Linear machine axes.

These are general applications of recirculating ball linear guides, not confirmed OEM applications of the exact R030101400 article.

Final suitability depends on the actual loads, required positioning accuracy, travel length and operating conditions.

Installation, Lubrication and Maintenance

Mounting Surface Preparation

Before installation, clean the guide rail and runner block mounting surfaces.

Remove burrs, dirt and other irregularities that could distort the guide system or affect its alignment.

Runner Block Installation

The runner block must be installed on a compatible guide rail.

Do not remove or transfer the runner block in a manner that could displace or damage the rolling elements.

Where required, use an appropriate mounting or transport rail to retain the balls during installation.

Alignment Accuracy

Incorrect rail alignment may cause additional internal stresses, uneven load distribution and premature wear.

In systems using multiple guide rails, their relative alignment is particularly important.

Lubrication

Use the lubricant and lubrication method specified for the exact Bosch Rexroth runner block configuration.

Do not assume that all runner blocks of the same nominal size have identical lubrication requirements.

Storage

Store the product in a clean, dry environment, protected against moisture and contamination.
