Electrically Insulated Ball Bearings
Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently. Shields keep out dust and contaminants.

Precision Needle-Roller Bearings
Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
Sealed bearings block out dust and other contaminants.
Shaft liners allow you to use the bearing on unhardened and unground shafts.

Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with nickel-plated cast iron housing are more corrosion resistant and durable than bearings with a cast iron housing.
Bearings with a set screw secure to shafts without using a collar. They let shafts rotate in both directions, so they’re good for applications where you need to reverse. However, the set screw will leave some marring on the shaft.

Low-Profile Mounted Ball Bearings
Designed with a thin, compact housing, these bearings are good for space-constrained applications.
Bearings with steel housing are stronger than bearings with stainless steel and aluminum housings. They are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with 304 stainless steel housing are more corrosion resistant than those with steel and aluminum housings. They are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Sealed bearings block out dust and other contaminants better than shielded bearings.

Mounted Ball Bearings with Two-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with a set-screw shaft mount secure to shafts with no need for an additional collar. They can be used for bi-directional shaft rotation when applications require reversing action. The set screw may cause some marring on the shaft.
Bearings with nickel-plated cast iron housing are more corrosion resistant and durable than bearings with a cast iron housing.
