Food and Beverage Linear Sleeve Bearings

Made of FDA-listed materials for use in food applications, these bearings also have excellent chemical and corrosion resistance. They have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included).

Fixed Alignment


With Retaining Ring Grooves	Without Retaining Ring Grooves

0.001" Shaft Clearance—Bearings with 0.001" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.

With Retaining Ring Grooves—For bearings with retaining ring grooves, secure them in your housing with two retaining rings (sold individually).

Food and Beverage Linear Sleeve Bearings for Support Rail Shafts

These bearings for use in food applications also have excellent chemical and corrosion resistance. Mount them on a support rail shaft for applications requiring maximum rigidity. They have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure in place with two retaining rings (sold individually).
