How to choose Rolling Bearings

Points to check when selecting, with the values for this product (Single-Row Angular Contact Ball Bearings 7200 BECBP / 7200 BEP Series).

  1. 1. Bore and housing bore dimensions

    This product: Inner diameter d 10 to 190 mm

    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. 2. Dynamic load rating based on life calculation

    This product: Basic dynamic load rating Cr 7.02 to 442 kN

    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. 3. Margin for static and shock loads

    This product: Basic static load rating C0r 3.35 to 600 kN

    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. 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. 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. 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.
