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

Flanged Ball Bearings

Flanged Ball Bearings

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

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

One-Way-Locking Ball Bearings

One-Way-Locking Ball Bearings

Prevent shafts from reversing direction

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

Dry-Running Flanged Ball Bearings

Dry-Running Flanged Ball Bearings

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