How to choose Rolling Bearings
Points to check when selecting, with the values for this product (SKF E2 Energy-Efficient Deep Groove Ball Bearing).
-
1. Bore and housing bore dimensions
Select the bore diameter d to match the shaft seat, the outside diameter D to match the housing bore, and the width B to suit the installation space. Main dimensions are standardized in ISO and JIS dimension series, so interchangeable products can be found by boundary dimension designation. For tapered roller bearings, also check the assembled width T; for thrust bearings, also check the height H.
-
2. Dynamic load rating based on life calculation
The basic dynamic load rating Cr is the reference value for calculating rated life. Verify that the required life is met using the equivalent load during operation and the rotational speed. For ball bearings, life is proportional to the cube of the load ratio, so providing load margin greatly extends life.
-
3. Margin for static and shock loads
The basic static load rating C0r is the allowable standard for permanent deformation generated at the rolling elements and raceways under stationary or low-speed conditions. For applications with oscillating motion or shock loads, confirm that a static safety factor against the maximum load is secured using C0r.
-
4. Operating speed and lubrication method
The limiting speed differs by lubrication method, and separate values are given for grease lubrication and oil lubrication. Confirm that the normal operating speed does not exceed the limiting value, and in high-speed ranges also consider cage material and precision grade. The reference speed can also be consulted as a thermal guideline.
-
5. Precision grade and internal clearance
Precision grades (P0, P6, P5, etc.) indicate rotational accuracy and dimensional accuracy; for high-precision applications such as machine tool spindles, select higher grades. Internal clearance (C2, CN, C3, etc.) is selected to allow for changes caused by interference fit and temperature differences during operation.
-
6. Materials and lubrication suited to the environment
For corrosive, high-temperature, vacuum, or clean environments, select specifications such as rings and rolling elements made of stainless steel or ceramics, or solid lubricants and fluorine grease for vacuum use. Check the operating temperature range, low dust generation, and whether food-grade grease registration applies against the application conditions.

Description
Friction is significantly reduced through optimized internal bearing geometry, a redesigned cage, and the use of a new low-friction grease. The bearing delivers its performance under conditions of rotational speed n > 1000 r/min and load P ≤ 0.125 C. Both-side shields and C3 radial internal clearance are standard. Suitable for electric motors, pumps, conveyors, fans, and similar equipment.

- Long service life
- Reduced lubricant and energy consumption
- Both-side shields as standard
- C3 radial internal clearance
Applications
- Electric motors
- Pumps
- Conveyors
- Fans
