The Bosch Rexroth R.RUNNER BLOCK CS RWA-125-FLS-C3-P-2 (R186333210) is a high-precision, heavy-duty roller runner block designed for robust performance in linear motion applications. This product is characterized by its steel CS construction and belongs to the FLS format, indicating a flanged width, long length, and standard height configuration. The runner block body is made of unalloyed steel and features a high preload class C, ensuring tight assembly with minimal play for applications requiring precision. With an accuracy class P, the roller runner block offers precise movement control suitable for various industrial uses. It does not come with a roller chain, initial lubrication, or attachment elements on either front reference edge. The product includes a straight lube connection that is loosely attached for ease of maintenance. The overall length of the runner block measures . mm. This Bosch Rexroth runner block boasts interchangeability with guide rails across all accuracy levels, providing flexibility in system design and replacement. It supports heavy loads with maximum rigidity in all directions and features additional mounting screw holes at the center to improve stability under liftoff and side loading conditions. High torque load capacity is also one of its key attributes. The product's design allows attachments to be mounted from both above and below, while lube nipples can be positioned on any side for convenient maintenance. Innovative channel designs ensure minimal lubrication requirements, contributing to smooth operation and longevity. The optimized return system and guideways of the rollers facilitate quiet running and consistent performance. Integrated front seals come standard with this model to protect running tracks and plastic parts from contaminants. The aluminum end caps are available for size 125 systems or plastic for other sizes mentioned in the specifications provided. In summary, the Bosch Rexroth R.RUNNER BLOCK CS RWA-125-FLS-C3-P-2 (R186333210) offers exceptional load capacity, precision movement control, versatile mounting options, easy maintenance access points, efficient lubrication channels, quiet operation with minimal elastic deflection variation—making it an ideal choice for demanding linear motion tasks in heavy machine construction environments.

General technical data and calculations

Accuracy classes

Definition of preload class

The preload class is the pre-tensioning force Fpr based on the dynamic load rating C of the particular roller runner block.

Selection of the preload class

Code	Application area
C1	Special version on request
C4
C5
C2	For precise guide systems with both high external loading and high demands on overall rigidity;also recommended for single rail systems.
	Above average moment loads can be absorbed without significant elastic deflection.
	Further improved overall rigidity with only medium moment loads.
C3	For highly rigid guide systems such as precision machine tools, etc.
	Above average loads and moments can be absorbed with the least possible elastic deflection.
	Roller runner blocks with preload C3 available in accuracy classes P, SP (GP) and UP only.

Recommended combination based on preload and accuracy class

Recommendation for preload C2: Accuracy classes H and P

Recommendation for preload C3: Accuracy classes P and SP (GP)

Combination of hard chrome plated roller runner blocks with hard chrome plated roller guide rails

Upon combination of hard chrome plated roller runner blocks with preload C2 or C3 and hard chrome plated roller guide rails, the preload increases by approx. half a preload class.
