Mounted Bearings with Three-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Steel bearings are stronger than stainless steel bearings, but not as corrosion resistant.

Chemical-Resistant Flange-Mounted Linear Sleeve Bearings
The Frelon liner on these bearings allows them to stand up to a wider range of chemicals than other flange-mounted linear sleeve bearings. All are self-aligning to compensate for shaft misalignment and are for use with round end-supported shafts. Note: Not for use with bare aluminum or chrome-plated shafts.
Bearings with 0.0005" shaft clearance are best for precision applications. Bearings with 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.

Flange-Mounted Linear Bearing Housings
Slide up to two linear ball or sleeve bearings into these housings and secure them with the included internal retaining rings.
Housings for two bearings give you better running accuracy and alignment than using two separate pillow blocks.

Vibration-Damping Flexible Shaft Couplings
Coupling Shown
Assembled
A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.
A complete coupling consists of two hubs, one tire, and two quick-disconnect bushings.
Quick-disconnect bushings are easy to install and remove. Tighten their cap screws to secure them to your shafts. For information on quick-disconnect bushing styles, see Quick-Disconnect (QD) Bushings.
