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, SP, GP and UP
Combination of hard chrome plated Roller Runner Block 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.

Project planning information
Effect of "Resist CR" coating on tolerances and preload
Differing tolerances for "Resist CR” coating
For Roller Runner Blocks and Roller Guide Rails in Resist CR, hard chrome-plated, be aware of differing tolerances with dimensions H and A3 (see "Accuracy classes and their tolerances")!
Higher preload upon combination of hard chrome-plated Roller Runner Blocks and hard chrome-plated Roller Guide Rails
When hard chrome-plated Roller Runner Blocks are combined with hard chrome-plated Roller Guide Rails, this increases the preload by approx. half a preload class.
