Ball Bearings

Ball Bearings

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

Light Duty Ball Bearings

Light Duty Ball Bearings

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

Permanently Lubricated Ball Bearings

Permanently Lubricated Ball Bearings

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

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

Dry-Running Ball Bearings

Dry-Running Ball Bearings

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

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

High-Load Dry-Running Ball Bearings

High-Load Dry-Running Ball Bearings

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

Other Products

Thrust Bearings

Thrust Bearings

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

Roller Bearings

Roller Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

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

Wheel Bearings

Reduce friction between the axle and the wheel for smooth movement

Shims

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

Steel

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

Thrust Roller Bearing Washers

Thrust Roller Bearing Washers

Adapt needle-roller thrust bearings for use on unhardened, unground surfaces

Roller Bearing Shaft Liners

Roller Bearing Shaft Liners

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

Bearing Nuts

Hold bearings, bushings, pulleys, and gears in place on threaded shafts and spindles

Drill Bushings

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

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Rod End Seals

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

Bronze

Better wear resistance than copper and brass—all with material certificates for traceability

Rod Ends

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

Stainless Steel

Stainless Steel

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