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

Plain Bearings

With no moving parts, the simplest type of bearing

Combination Roller Bearings

Combination Roller Bearings

Support both radial and thrust loads with a single bearing

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Bearing Housings

Bearing Housings

Mount your own bearings in place

Bearing Washers

Bearing Washers

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

Bearing Nuts

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

Turntable Bearings

Turntable Bearings

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

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

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

Lead Screws and Nuts

Lead Screws and Nuts

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

Ball Screws and Nuts

Ball Screws and Nuts

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

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Ball Screw/Splines

Ball Screw/Splines

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

Roller Screws and Nuts

Roller Screws and Nuts

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

Positioning Slides

Positioning Slides

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

Bore Reducers

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

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

Gear and Bearing Pullers

Gear and Bearing Pullers

Remove gears and bearings from hollow shafts and housings

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

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Plastic

A lightweight alternative to metal and glass

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

Fastening and Joining

Shims

Level, align, and adjust spacing on fasteners, shafts, and machine components
