Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
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.

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.
Sealed bearings block out dust and other contaminants better than shielded bearings.
Bearings with an 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. However, they only work on shafts that spin in one direction.

Mounted Ball Bearings with Two-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with an eccentric-lock shaft mount are better than bearings with a set-screw shaft mount for high-speed applications, but only rotate in a single direction.

Mounted Ball Bearings with Four-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Eccentric lock bearings are quick to install—twist them in one direction to tighten and the opposite to loosen. They’re better than set screw bearings for high speed applications, but they only work with shafts that rotate in one direction.

Insert Bearings
Swap out worn inserts instead of replacing the entire mounted unit. Use the manufacturer model number on your existing mounted bearing to choose a compatible insert. Inserts must be used with the manufacturer model number specified.
Bearings with eccentric lock have a collar that grips in one direction and releases in the other. They are easier to install onto shafts than bearings with a set screw grip and require less adjustment over time. Use with shafts that spin in one direction only.

Hex Flanged Eccentric Bushings
Often used with V-groove wheels or track roller carriages, these off-center bushings create precise mounting clearance. As you turn the bushing’s hex flange with a wrench, it adjusts the distance between the V-groove wheel or carriage and the rail. Tighten the axle bolt in place once you’ve adjusted them. Made of 303 stainless steel, these bushings have very good corrosion resistance.
