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

Angular Contact Ball Bearings

Angular Contact Ball Bearings

Support radial and thrust loads at the same time

Flanged Ball Bearings

Flanged Ball Bearings

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

Ball Bearings for Food and Beverage

Ball Bearings for Food and Beverage

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

Dry-Running Flanged Ball Bearings

Dry-Running Flanged Ball Bearings

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

Self-Aligning Ball Bearings

Self-Aligning Ball Bearings

The balls rock back and forth to compensate for misalignment

Ball Bearings with Retaining Ring

Ball Bearings with Retaining Ring

Install without complicated tools

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

Electrically Insulating Ball Bearings

Electrically Insulating Ball Bearings

Ceramic balls insulate against stray currents that can damage bearings

One-Way-Locking Ball Bearings

One-Way-Locking Ball Bearings

Prevent shafts from reversing direction

Dry-Running Ball Bearings

Dry-Running Ball Bearings

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

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

Roller Bearings

Roller Bearings

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

Flanged Sleeve Bearings

Flanged Sleeve Bearings

A sleeve and thrust bearing in one to support both parallel and perpendicular loads

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Thrust Bearings

Thrust Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Rod Ends

Use with connecting rods to support loads and control steering, tensioning, or pivoting motion

Mounted Bearings

Mounted Bearings

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

Bearing Housings

Bearing Housings

Mount your own bearings in place

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Shims

Align and space components on shafts, or level machinery, cabinets, and doors

Swivel Joints

Handle shaft misalignment where ball joint rod ends won’t fit; also known as spherical bearings

Roller Bearing Shaft Liners

Roller Bearing Shaft Liners

Adapt precision needle-roller bearings for use on unhardened, unground shafts

Drill Bushings

Fit in holes to guide drill bits and other cutting tools for precise and repeatable holes and cuts

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

Mount between a rotating shaft and equipment to secure the shaft and reduce vibration

Track Rollers

Support and carry objects as they move along conveyor systems

Rod End Inserts

Rod End Inserts

Attach to rod ends to increase the amount of misalignment they can handle

Grommets

Protect wire, cable, and cords from holes with sharp or rough edges

Rod End Seals

Keep dirt out and lubrication in to extend the life of rod ends

Drive Rollers

Transmit power from motors to systems like conveyors; also known as contact wheels and feed rollers

Bearing Lock Washers

Bearing Lock Washers

Lock bearing nuts in place to prevent loosening due to vibration

Bore Reducers

Adapt the bore of a component to a smaller size for mounting on a shaft
