	Determination of the dynamic load ratings and load moments is based on a 100,000 m stroke in accordance with DIN ISO 14728-1. Often only 50,000 m are actually stipulated. For comparison: Multiply values C, Mt, and ML from the table by 1.23.

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.
