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

Quick-Mount Ball Bearings

Quick-Mount Ball Bearings

Slip onto a shaft and secure with the turn of a screw

Light Duty Flanged Ball Bearings

Light Duty Flanged Ball Bearings

Reduce friction and resist thrust loads in parts that don't require high speed or precision

Ball Bearings for Food and Beverage

Ball Bearings for Food and Beverage

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

Insert Bearings

Insert Bearings

Swap out worn inserts instead of replacing the entire mounted unit

High-Precision Ball Bearings

High-Precision Ball Bearings

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

Flanged Ball Bearings

Flanged Ball Bearings

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

Dry-Running Ball Bearings

Dry-Running Ball Bearings

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

Hex-Bore Ball Bearings

Hex-Bore Ball Bearings

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

Quick-Mount Ball Bearings for Food and Beverage

Install in food production areas without using special tools

Four-Point Angular Contact Ball Bearings

Four-Point Angular Contact Ball Bearings

Support complex movement in multiple directions

Dry-Running Flanged Ball Bearings

Dry-Running Flanged Ball Bearings

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

High-Precision Angular Contact Ball Bearings

High-Precision Angular Contact Ball Bearings

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

One-Way-Locking Ball Bearings

One-Way-Locking Ball Bearings

Prevent shafts from reversing direction

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

Ball Bearings with Retaining Ring

Ball Bearings with Retaining Ring

Install without complicated tools

Angular Contact Ball Bearings

Angular Contact Ball Bearings

Support radial and thrust loads at the same time

Square-Bore Ball Bearings

Light Duty Ball Bearings with Retaining Ring

Install by hand in parts that don't require high speed or precision

Other Products

Ball Transfers

Install in arrays to create platforms for conveying, rotating, and positioning heavy objects

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments—all with material certificates for traceability

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Roller Bearings

Roller Bearings

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

Mounted Bearings

Mounted Bearings

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

Plastic

A lightweight alternative to metal and glass

Aluminum
