Ball Bearings

Create less friction than other bearings for use at high speeds

Plain Bearings

With no moving parts, the simplest type of bearing

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

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 Shaft Liners

Bearing Shaft Liners

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

Pivot Bearings

Best for applications that require small, precise oscillating motion with limited twisting

Bearing Adapter Sleeves

Bearing Adapter Sleeves

Close gaps between your bearing and shaft for a tight fit

Bearing Nuts

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

Linear Bearing Housings

Linear Bearing Housings

Hold linear ball or sleeve bearings by sliding them in and securing with retaining rings

Turntable Bearings

Turntable Bearings

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

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

Idler Rollers

Guide boxes and parts as they pass through 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 Inserts

Rod End Inserts

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

Rod End Seals

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

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

Lead Screws and Nuts

Lead Screws and Nuts

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

Positioning Slides

Positioning Slides

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

Guide Rail Carriages

Guide Rail Carriages

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

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Bore Reducers

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

Shaft Couplings

Shaft Couplings

Connect two shafts to transfer rotary motion from one to the other

Ball Screws and Nuts

Ball Screws and Nuts

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

Shaft Collars

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

Air Slides

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

Electric Actuators

Electric Actuators

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

Material Handling

Ball Transfers

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

Ball Transfer Stops

Ball Transfer Stops

Raise to hold loads in place and lower to let them through

Ball Transfer Plates

Ball Transfer Plates

Rest on flat surfaces to create platforms for conveying, rotating, and positioning heavy objects

Ball Transfer Plate Covers

Ball Transfer Plate Covers

Place a smooth surface over ball transfer plates so small items won't get caught between

Conveyor Roller Bearings

Conveyor Roller Bearings

Replace bearings on conveyor rollers, or press into tubing or pipe to create a roller

Conveyor Belt Take-up Bearings

Conveyor Belt Take-up Bearings

Use with take-up frames to adjust tension on conveyor belts

Screw Conveyors

Screw Conveyors

Push material through fixed troughs

Skate Wheels

Replace wheels on skate wheel conveyors or add wheels for a custom setup

Conveyor Belt Take-up Frames

Conveyor Belt Take-up Frames

Adjust the tension on conveyor belts by extending or retracting pulleys

Wheel Bearings

Reduce friction between the axle and the wheel for smooth movement

Wheel Reducer Bushings

Wheel Reducer Bushings

Reduce the inside diameter of a bearing to fit a particular axle size

Pallet Stands

Hold pallets above the floor at a useful working height

Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Bronze

With better wear resistance than copper and brass, it’s used for bearings, gears, and pump parts

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

Glass

Clear and highly heat and chemical resistant; often used in sights, lighting, and lab equipment

Nickel

An upgrade from stainless steel that withstands harsh chemicals and acids at high temperatures

Building and Machinery Hardware

Turntables

Rotate to reposition machinery and equipment

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

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

Fastening and Joining

Shims

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