About Ball and Roller Bearings

Found anywhere from machine tool spindles to conveyor rollers, these bearings have a two-piece design that allows for adjustment.

Zinc-plated steel bearings provide better corrosion resistance than steel bearings.

Tapered-Roller Thrust Bearings

Open

Sealed

Thick, tapered rollers stand up to extremely high thrust loads.

Open bearings dissipate heat more efficiently than sealed bearings.

Sealed bearings have better dust resistance than open bearings, but retain more heat.

Mounted Roller Bearings

Roller bearings have a thinner profile and larger contact area than ball bearings, making them stronger and more space-efficient than ball bearings.

Sealed bearings block out dust and contaminants.
