Ball Bearing Speeds and Loads
This comparison uses the speed and load capability of carbon steel ball bearings as the benchmark of 100%
- The overall capability of 400-series stainless ball bearings (most stainless bearings are 400-series) is
approximately 50% that of carbon-steel bearings. 400-series stainless ball bearings offer considerably more
corrosion resistance than carbon-steel bearings.
- The overall capability of 300-series stainless ball bearings (available in limited shaft sizes) is approximately
25% that of carbon-steel bearings. 300-series stainless offers more corrosion resistance than 400-series
stainless bearings.
Maximum speeds and maximum loads for 400-series stainless ball bearings are shown below.
For optimum bearing life, the appropriate balance of speed and load must be considered.

Where to Use Ball Bearings
In applications where plane bearings are not recommended, ball bearings are the best
alternative. These include:
|
APPLICATIONS WHERE BALL BEARINGS ARE WELL-SUITED
- High tension applications (V-belt drives, flat belt conveyors, urethane belts)
- High speed devices (fans, pumps, table top conveyors)
- Overhung loads (shaft mounted gear reducers)
- Trunnion applications
In other applications where the integrity of grease is compromised, consider using
plane bearings.
