Ball Bearings

Ball Bearings

The balls roll nearly friction free for smooth movement between rotating parts

Permanently Lubricated Ball Bearings

Permanently Lubricated Ball Bearings

Solid lubricant releases oil over time so you never need to add more

Light Duty Ball Bearings

Light Duty Ball Bearings

Reduce friction between rotating parts that don't require high speed or precision

Flanged Ball Bearings

Flanged Ball Bearings

The flange presses against a housing wall so thrust loads won't knock them off-kilter

Angular Contact Ball Bearings

Angular Contact Ball Bearings

Support radial and thrust loads at the same time

High-Precision Ball Bearings

High-Precision Ball Bearings

The most precise ball bearings we offer, with tolerances tighter than a speck of dust

Ball Bearings for Food and Beverage

Ball Bearings for Food and Beverage

The FDA-compliant lubricant is safe for food-processing areas

Self-Aligning Ball Bearings

Self-Aligning Ball Bearings

The balls rock back and forth to compensate for misalignment

Dry-Running Ball Bearings

Dry-Running Ball Bearings

Made of slippery plastic so there's no lubricant to maintain or make a mess

Four-Point Angular Contact Ball Bearings

Four-Point Angular Contact Ball Bearings

Support complex movement in multiple directions

Electrically Insulating Ball Bearings

Electrically Insulating Ball Bearings

Ceramic balls insulate against stray currents that can damage bearings

High-Load Dry-Running Ball Bearings

High-Load Dry-Running Ball Bearings

Carry twice as much weight as standard dry-running ball bearings

High-Precision Angular Contact Ball Bearings

High-Precision Angular Contact Ball Bearings

Our most precise bearings for tackling radial and thrust loads at once

Ball Bearings with Retaining Ring

Ball Bearings with Retaining Ring

Install without complicated tools

Hex-Bore Ball Bearings

Hex-Bore Ball Bearings

No need for set screws—the inside corners hold tightly to hex shafts

Dry-Running Flanged Ball Bearings

Dry-Running Flanged Ball Bearings

Don't risk your bearing popping out of place or making a mess

One-Way-Locking Ball Bearings

One-Way-Locking Ball Bearings

Prevent shafts from reversing direction

Tapered-Bore Ball Bearings

Tapered-Bore Ball Bearings

Mount on tapered shafts

High-Precision Flanged Ball Bearings

High-Precision Flanged Ball Bearings

Our most precise flanged ball bearings stay put in their housing when rocked by thrust loads

Square-Bore Ball Bearings

Square-Bore Ball Bearings

The inside corners grip square shafts so you don't need set screws

High-Temperature Graphite-Lubricated Ball Bearings

High-Temperature Graphite-Lubricated Ball Bearings

Keep parts spinning in industrial ovens and other places as hot as 660° F

Other Products

Thrust Bearings

Thrust Bearings

Support loads parallel to the shaft with plain, ball, or roller bearings

Mounted Bearings

Mounted Bearings

Ball, roller, and sleeve bearings ready to bolt in place

Roller Bearings

Roller Bearings

Support higher loads than ball bearings, but run at lower speeds

Conveyor Roller Bearings

Conveyor Roller Bearings

Replace bearings on conveyor rollers, or press into tubing or pipe to create a roller

Guide Rail Carriages

Guide Rail Carriages

Carry loads along guide rails on accurate and repeatable paths in automated systems

T-Slotted Framing Linear Bearings

T-Slotted Framing Linear Bearings

Reduce friction in repeated and automated motion along T-slotted framing
