New Clean Pro-PR Specification Hybrid Ceramic Linear Ball Bearing

Specifications

How to choose Linear Guides

Points to check when selecting, with the values for this product (New Clean Pro-PR Specification Hybrid Ceramic Linear Ball Bearing).

1. 1. Select the type and size to match the shaft diameter

   Linear ball bearings are used with the outer sleeve mounted on a shaft, so the shaft diameter d must match the shaft. The listed products have shaft diameters of 3 to 60 mm. The type and size are determined by the bearing number, so check the outer diameter D together with the shaft diameter and confirm that it fits the housing bore dimensions.

2. 2. Check the basic dynamic load rating for load and life

   The basic dynamic load rating C is the reference load used when calculating rated life. The listed products range from 20.3 to 323 N. Determine the required life from the actual applied load and operating conditions, then select a size with sufficient margin over C, or a roller type or double-block type.

3. 3. Use the static load rating for stationary and shock loads

   The basic static load rating C0 is the reference for the permissible load when the unit is stationary or subjected to shock loads. To prevent permanent deformation of the rolling elements and raceways, secure a static safety factor against the maximum load. This is especially important in applications with moment loads.

4. 4. Match rail length and stroke

   In finite-stroke types such as crossed roller ways, the usable stroke is determined by the rail length L and the length of the retainer. The listed products have rail lengths of 80 to 600 mm. Confirm that the length is sufficient for the required stroke and fits within the installation space.

5. 5. Determine accuracy grade and preload by application

   Accuracy classes such as parallelism of travel and preload (the tightness of the internal clearance) affect positioning accuracy and rigidity. Increasing preload raises rigidity but also increases frictional resistance. Select based on the balance between the accuracy required by the equipment and smooth, light motion.

6. 6. Select materials and specifications suited to the environment

   In cleanroom, vacuum, corrosive, and high-temperature environments, the body and rolling element materials, lubrication method, and presence of seals differ from standard products. To prevent particle generation, gas emission, and rust, select products with materials and specifications suited to the operating environment. Where necessary, also check non-magnetic or insulating specifications.
