6mm Wide Bearings | McMaster-Carr

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Self-Aligning Ball Bearings

With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

Permanently Lubricated Stainless Steel Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Bearings are 440C stainless steel.

Precision Stainless Steel Ball Bearings

Made to tight tolerances, these 440C stainless steel bearings combine speed and accuracy with corrosion resistance.

Food Industry Permanently Lubricated
Stainless Steel Ball Bearings

Good for applications with incidental food contact, these 440C stainless steel bearings have a food-grade, solid polymer lubricant between the balls and race that eliminates the need for additional lubrication.

Ultra-Corrosion-Resistant Stainless Steel Ball Bearings

These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.

Plastic Ball Bearings

Made of slippery plastic, these bearings do not require lubrication and have excellent corrosion and chemical resistance.

Water-Resistant Plastic Ball Bearings

Made of PVDF, these bearings resist moisture absorption, so they won’t warp in underwater applications.

Flanged Ball Bearings

The flange ensures proper positioning inside a tube or housing.

Flanged Ultra-Thin Ball Bearings

Flanged and creating twice as many contact points as angular-contact ball bearings, these bearings ensure correct positioning within a tube or housing and resist radial loads.

Ultra-Thin Ball Bearings

These bearings have twice as many contact points as angular-contact ball bearings.

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together.

Bearing Retaining Nuts

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

Bearing Retaining Jam Nuts

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.
