How to choose Deep Groove Ball Bearings

Points to check when selecting, with the values for this product (Stainless Steel Deep Groove Ball Bearing).

1. 1. Main dimensions to suit shaft and housing

   This product: Inner diameter d 0.6〜50 mm

   Select the bore diameter d to match the shaft diameter, the outside diameter D to match the housing bore, and the width B to suit the installation space. The listed products cover a wide range of bore diameters from 0.6 to 1420 mm, and even at the same bore diameter there are dimension series with different outside diameters and widths. Since load capacity and mass change with the dimension series, confirm the three dimensions in combination.

2. 2. Basic dynamic load rating for life calculation

   This product: Basic dynamic load rating Cr 0.034〜28.6 kN

   The basic dynamic load rating Cr is the reference value for calculating rolling fatigue life, and life is estimated from the ratio of the actual applied load to Cr. For high loads or when long life is required, select a bearing with a larger Cr. Bearings made of special materials may have lower ratings than steel bearings of the same dimensions, so confirm life under the operating conditions.

3. 3. Check static and shock loads against static rating

   This product: Basic static load rating C0r 0.007〜19 kN

   The basic static load rating C0r is the guideline load at which permanent deformation does not occur, applicable when stationary, rotating at low speed, or subjected to shock loads. For applications with oscillating motion or large loads while stopped, select with emphasis on the ratio to C0r (static safety factor) rather than the dynamic rating.

4. 4. Internal clearance to suit fit and temperature

   Radial internal clearance decreases during operation due to interference fits and temperature differences between the inner and outer rings. Clearances larger than standard, such as C3, are used in applications where the inner ring tends to expand, such as motors or high-temperature environments. Clearance that is too small leads to heat generation and seizure, so determine the class from the fit and operating temperature.

5. 5. Materials and lubrication suited to the environment

   Stainless steel or ceramics (silicon nitride, zirconia, silicon carbide) are used in water or chemical solutions, while solid lubricants such as graphite or fluorine-based solids and fluorine grease are used in high-temperature, vacuum or clean environments. Listed products have maximum operating temperatures of 250 to 350°C, so select the material and lubrication method based on temperature, atmosphere and dust-generation requirements.

6. 6. Check speed limits and electrical corrosion countermeasures

   Confirm that the limiting speed and reference speed exceed the operating speed. In equipment where shaft current flows, such as inverter-driven motors, hybrid bearings with insulating-coated or ceramic balls can prevent electrolytic corrosion. Ceramic balls are lighter than steel balls, so the effect of centrifugal force is reduced even at high speeds.
