High-Load Ball Bearings
These tough bearings, which have a larger profile than typical ball bearings, are suitable for supporting heavy loads at slow speeds.
Compared to shielded and sealed bearings, open bearings are more effective at dissipating heat.
Although shielded bearings keep out dust and other impurities, they are less effective at dissipating heat than open bearings.
Although sealed bearings retain the most heat, they are the best at keeping out dust and other impurities compared to open and shielded bearings.
Bearings that have an enlarged inner ring offer more shaft support.
In bearings with retaining rings, the bearing is held inside a housing by a detachable holding ring.
