Load and Speed
1. Table 6 displays the Sealmaster Gold and Material Handling ball bearing load capacities for a given L10 life, speed
and shaft size.
2. Values in Table 6 represent radial loads at ideal conditions with press t mounting to the shaft. ABMA
recommends de-rating of slip t mounted bearings. Elevated operating temperatures can reduce the load capacity
of bearing steel where a material de-rating is also recommended.
a.
For operating temperatures up to 200°F, divide the value in the load table by 1.3 to obtain the slip t derated value.
b. For units designed for operating temperatures 200°F to 400°F, divide the value in the load table by 1.5 to
obtain the slip t/elevated temperature de-rate value.
c. Values in Table 6 represent equivalent radial loads only. For combined radial/thrust loads see page G-222.
3. The gray shaded area indicates the maximum speed ratings for Skwezloc concentric locking collar and double
setscrew lock bearings (applicable on sizes available). All speeds listed are for the standard felt seal. For speed
ratings using alternate seals, see pages G-235 to G-240.
4. The double line indicates the maximum speed ratings of material handling bearings.
5. The blue shaded area represents maximum recommended load for given operating speed based on load of 25%
BDR. It is NOT recommended to exceed these loads in general industrial applications. See note on page G-222 for
high load applications.
6. Areas designated by “-” exceed maximum value for standard bearings. See note on page G-223.
7. Consult Application Engineering for load and speed applications not covered in this table.

How to Read the Table
Example A: For a 1” standard duty ball bearing operating at 1000 RPM and desired 100,000 hours L10 life, 154 Lbs is the maximum allowable radial load.
Example B: If 230 lbs of radial load is applied to a 1” standard duty shaft operating at 1000 RPM, the resulting L10 life is 30,000 hours.
