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.
Bearings with eccentric lock have a collar that you twist in one direction to grip and the other to release. Compared to bearings with a set screw, they’re easier to install, require less adjustment over time, and are better for high-speed applications. But, they only work on shafts that spin in one direction.

Permanently Lubricated Mounted Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Seals block out dust and contaminants.

High-Speed Mounted Ball Bearings
These bearings have the highest speed ratings of any mounted ball bearing that we offer. The clamp-on collar creates a 360° grip around the shaft for a strong, mar-free hold. Bearings are self-aligning to compensate for shaft misalignment.
Sealed bearings block out dust and other contaminants better than shielded bearings.

Washdown Mounted Ball Bearings
Meeting IP69K for washdown environments, these mounted ball bearings are used in food, beverage, pharmaceutical, and chemical plants. All have NSF registered H1 lubrication, which is certified for incidental contact with food and is suitable for food and beverage applications. Made of 316 stainless steel, they resist corrosion and prevent rusting caused by salt water, chlorine solutions, and chemicals.
Set screw bearings secure to shafts as you tighten their screw. They don’t need a collar, but the screw does leave some marring on shafts.
Snap optional covers onto bearings to shield them from moisture. Made of polypropylene, they resist corrosion, won’t absorb water, and are FDA compliant.

High-Temperature Mounted Ball Bearings
Synthetic grease or graphite enables these bearings to operate in high temperatures. They have an extended inner ring for additional shaft support. Seals block out dust and contaminants.
Bearings with synthetic grease operate in temperatures up to 400° F, nearly double the temperature of standard ball bearings. They’re self-aligning to compensate for shaft misalignment.
Bearings with graphite operate in temperatures up to 660° F, three times that of standard ball bearings, so they're a good choice for use in industrial ovens. However, they’re only for low-speed applications.
