The Bosch Rexroth R.RUNNER BLOCK CS RWD-045-FNS-C2-P-2 (R18514222X) is a high-precision roller runner block designed for linear motion applications requiring precision and rigidity. This runner block boasts size 45 dimensions with a flanged width, normal length, and standard height. Constructed from unalloyed steel CS, it offers a medium preload class C and falls within the precision accuracy class P. Notably, it does not come with an initial lubrication or attachment elements on either front reference edge, but it does include a straight lube connection that is loosely attached. The RWD-045-FNS-C2-P-2 runner block is engineered to provide high torque load capacity and maximum rigidity in all loading directions, thanks to additional screw connections on two bore holes at the center of the block. Its design ensures unrestricted interchangeability, allowing combination with all guide rail versions and roller runner block variants. The innovative channel design minimizes lubrication requirements while ensuring smooth and quiet operation through optimally designed return and guideways for the rollers. Attachments can be mounted from both above and below the runner block, which slides onto the rail with a transport lock for easy installation. It features integrated all-around sealing as standard for added protection against contaminants. The product also offers excellent dynamic load capacity C as well as static longitudinal moment load capacity ML, making it suitable for various applications where high precision and load handling are essential. Overall, the Bosch Rexroth R.RUNNER BLOCK CS RWD-045-FNS-C2-P-2 (R18514222X) represents an advanced solution in linear motion technology, providing users with durability, interchangeability, ease of maintenance, and unparalleled performance in demanding 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.
