How can we improve?

8,007 Products

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

Quick-Mount Ball Bearings

Quick-Mount Ball Bearings

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

Ball Bearings for Food and Beverage

Ball Bearings for Food and Beverage

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

High-Precision Ball Bearings

High-Precision Ball Bearings

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

Angular Contact Ball Bearings

Angular Contact Ball Bearings

Support radial and thrust loads at the same time

Insert Bearings

Insert Bearings

Swap out worn inserts instead of replacing the entire mounted unit

Self-Aligning Ball Bearings

Self-Aligning Ball Bearings

The balls rock back and forth to compensate for misalignment

Electrically Insulating Ball Bearings

Electrically Insulating Ball Bearings

Ceramic balls insulate against stray currents that can damage bearings

Ball Bearings with Retaining Ring

Ball Bearings with Retaining Ring

Install without complicated tools

One-Way-Locking Ball Bearings

One-Way-Locking Ball Bearings

Prevent shafts from reversing direction

Quick-Mount Ball Bearings for Food and Beverage

Quick-Mount Ball Bearings for Food and Beverage

Install in food production areas without using special tools

High-Precision Angular Contact Ball Bearings

High-Precision Angular Contact Ball Bearings

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

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

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

Square-Bore Ball Bearings

Square-Bore Ball Bearings

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

Hex-Bore Ball Bearings

Hex-Bore Ball Bearings

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

Other Products

Mounted Bearings

Mounted Bearings

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

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Flanged Sleeve Bearings

Flanged Sleeve Bearings

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

Roller Bearings

Roller Bearings

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

Track Rollers

Support and carry objects as they move along conveyor systems

Thrust Bearings

Thrust Bearings

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

Idler Rollers

Guide boxes and parts as they pass through conveyor systems

Carriages

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

Turntables

Rotate to reposition machinery and equipment

Turntable Bearings

Turntable Bearings

Support machinery that slowly turns or oscillates, such as a rotating hoist

Rod Ends

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Idler/Drive Rollers

Idler/Drive Rollers

Spin freely in one direction on conveyor systems and lock to transmit power in the other direction

Ball Screw/Splines and Bearings

Ball Screw/Splines and Bearings

Transmit rotary power, move loads along the shaft, or do both at once

Telescoping Rails

Telescoping Rails

Carry heavy loads, such as in pick-and-place applications, machine tool doors, and press arms

Ball Spline Bearings

Ball Spline Bearings

Pair with ball splines for applications requiring complex, fast movements, such as robotics

Electric Actuators

Electric Actuators

Push and pull loads with more precise positioning than air and hydraulic cylinders

Positioning Slides

Positioning Slides

A lead screw drives the carriage for accurate positioning in laboratory and production equipment

Electric Slides

Electric Slides

Move parts with precision in electronics, robotics, and other automated processes

Swivel Joints

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

Die Bushings

Guide pins and punches in molds and stamping dies or reduce friction between ejector pins and plates

Linear Drive Nuts

Linear Drive Nuts

Create a linear positioning system on a rotary shaft without a lead screw
