Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Roller Bearings

Roller Bearings

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

Thrust Bearings

Thrust Bearings

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

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

Mounted Bearings

Mounted Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Bearing Housings

Bearing Housings

Mount your own bearings in place

Turntable Bearings

Turntable Bearings

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

Bearing Nuts

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

Bearing Washers

Bearing Washers

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

Bearing Shaft Liners

Bearing Shaft Liners

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

Bearing Adapter Sleeves

Bearing Adapter Sleeves

Close gaps between your bearing and shaft for a tight fit

Bearing Lock Washers

Bearing Lock Washers

Lock bearing nuts in place to prevent loosening due to vibration

Linear Bearing Brakes

Linear Bearing Brakes

Lock bearings in place on a shaft for precise positioning

Track Rollers

Support and carry objects as they move along conveyor systems

Drive Rollers

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

Rod Ends

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

Rod End Seals

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

Rod End Inserts

Rod End Inserts

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

Swivel Joints

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

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

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

Shaft Collars

Hold and position parts on a shaft, or limit shaft movement

Ball Screws and Nuts

Ball Screws and Nuts

Internal ball bearings roll on screws for low friction when moving components at high speeds

Lead Screws and Nuts

Lead Screws and Nuts

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

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Ball Screw/Splines

Ball Screw/Splines

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

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Roller Screws and Nuts

Roller Screws and Nuts

More contact points to move heavier loads than ball and lead screw assemblies

Bore Reducers

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

Positioning Slides

Positioning Slides

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

Air Slides

Convey grippers, printing heads, and other loads back and forth on a carriage

Fabricating and Machining

Drill Bushings

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

Bearing Separators

Bearing Separators

Separate bearings, collars, hubs, and other shaft-mounted items so you can remove them

Gear and Bearing Pullers

Gear and Bearing Pullers

Remove gears and bearings from hollow shafts and housings

Bearing and V-Belt Pulley Separator Sets

Separate bearings or V-belt pulleys of various sizes with these sets

Fastening and Joining

Shims

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

Material Handling

Ball Transfers

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

Raw Materials

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Plastic

A lightweight alternative to metal and glass

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Aluminum

Lightweight, easy to machine, and corrosion resistant in wet environments

Building and Machinery Hardware

T-Slotted Framing and Fittings

T-Slotted Framing and Fittings

The most versatile system, attach fittings along the continuous slots to build virtually anything

Grommets

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