The Bosch Rexroth R.RUNNER BLOCK CS RWA-065-FXS-C2-S-2 (R185462110) is a high-precision roller runner block designed for linear motion applications requiring extreme accuracy and rigidity. This runner block is part of the R series, which is known for its robustness and versatility in various industrial applications. The RWA-065-FXS-C2-S-2 model features a steel CS body, with an FXS format indicating a flange width, extra-long length, and standard height. The preload class C signifies a medium preload, while the accuracy class SP denotes super precision capabilities. This runner block does not include a roller chain, is preserved but without initial lubrication, and lacks attachment elements on both the left and right front reference edges. It has a straight lube connection that comes loosely attached. The standard version of the runner block body has an overall length specified by the manufacturer. The Bosch Rexroth roller runner block boasts interchangeability with guide rails across all accuracy levels, ensuring limitless combination options. It is engineered to handle heavy-duty machine construction with extremely high load capacities. Its design includes additional mounting screw holes at the center for enhanced rigidity under liftoff and side loading conditions. The unit allows for attachments to be mounted from both above and below, simplifying maintenance tasks with lube nipples possible on all sides of the block. The innovative channel design ensures minimum lubrication quantities are required for operation. Moreover, it offers smooth and quiet running due to its optimally designed return and guideways for rollers. To ensure minimal variation in elastic deflection during use, it features optimized entry-zone geometry along with a high number of rollers. End caps made from either aluminum or plastic enhance the product's durability and longevity. The product adheres to DIN ISO standards regarding dynamic load capacity C determination based on a 100,000 m travel distance with an option to compare against typically stipulated 50,000 m distances by adjusting values accordingly. In summary, this Bosch Rexroth roller runner block is engineered for demanding applications where precision movement and high load capacity are critical factors. Its design facilitates easy maintenance while offering robust performance suited to heavy-duty machine construction environments.

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.
