About Ball and Roller Bearings

More

Thrust Ball Bearings

Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components. With an open design, they dissipate heat more efficiently than one-piece thrust ball bearings.

Bearings with steel cage and with bronze cage handle higher loads and speeds than bearings with a plastic cage.
