Dry-Running Flanged Sleeve Bearings for Food and Beverage

Made of plastics permitted by the US FDA for contact with food, these bearings won’t release harmful, smelly, and distasteful impurities into your food or beverage production line. These self-lubricating plastics eliminate the need for oil, resulting in less maintenance and improved hygiene. You’ll find them inside food-processing equipment such as mixers, conveyors, and fillers.

Flanged sleeve bearings combine a sleeve and thrust bearing in one. The flange supports thrust loads and prevents the bearing from being pushed out of place. The sleeve is the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

Ultra-Low-Friction Rulon 641—Get effortless motion with strength surpassing UHMW polyethylene. Rulon 641 bearings can also operate from cryogenic to oven-like temperatures.

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).

Dry-Running Thrust Bearings for Food and Beverage

Made of slippery, FDA-compliant plastic, these bearings are safe to directly touch food. Install them right inside food-processing equipment, such as mixers and fillers. They won’t impart odors, tastes, or harmful impurities, plus there’s no lubricant that could drip off or wash out. With no lubricant to replenish, these bearings also reduce maintenance and downtime.

Ultra-Low-Friction Rulon 641—Get effortless motion with strength surpassing UHMW polyethylene. Rulon 641 bearings can also operate from cryogenic to oven-like temperatures.

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).
