Low-Profile Mounted Ball Bearings with Two-Bolt Flange
Designed with a thin, compact housing, these bearings are good for space-constrained applications. Seals block out dust and contaminants.
Steel bearings are stronger than stainless steel bearings, but not as corrosion resistant.
Stainless steel bearings are more corrosion resistant than steel bearings.
Self-aligning bearings compensate for shaft misalignment.

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.
Shielded bearings dissipate heat more efficiently than sealed bearings.
Bearings with extended inner ring provide additional shaft support.

Low-Profile Sleeve Bearing Carriages and Guide Rails
For applications with low clearance, these carriages protrude less than 5 mm above their rails. Use them for light to moderate loads, as well as frequent starting and stopping applications where tight tolerances are not required. Sleeve bearings allow them to outperform ball bearings in wet, dirty, and high-vibration environments. Mount in any orientation without affecting load capacity.

High-Cycle Low-Profile Ball Bearing Carriages and Guide Rails
Run many cycles in tight spaces before replacing or re-greasing carriages. These low-profile carriages have a plastic cage surrounding the ball bearings to keep them from colliding with each other. This reduces the noise, heat, friction, and dust they produce, so carriages can travel back and forth along the rail many times. The cage also traps grease around the balls and makes sure they roll in the same direction. Ball bearings provide accurate movement and positioning at high speeds under heavy loads. Made of stainless steel, all of these carriages and guide rails are corrosion resistant. Each carriage has end seals to keep lubricant in and dirt out.
Mounting hole plugs protect mounting fasteners from corrosion.
