Metric Dampers | McMaster-Carr

Select these bumpers for applications that require specific load capacities. All are reinforced with a base plate for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Twist these bumpers into a threaded hole.

Heavy Duty Threaded-Stud Bumpers

All of these bumpers are reinforced with a steel core for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines. Twist them into a threaded hole.

High-Temperature Load-Rated Threaded-Stud Bumpers

These bumpers withstand temperatures up to 300° F, which is twice as high as our other load rated bumpers. Use them in applications that require specific load capacities. All are reinforced with a base plate for strength. Often used as feet, spacers, and vibration dampers, these bumpers absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Twist them into a threaded hole.

Threaded Bumpers

Mount these bumpers on a threaded stud. All are reinforced with a steel core or base plate for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines.

Load-Rated Threaded Bumpers

High-Temperature Load-Rated Threaded Bumpers

All are reinforced with a base plate for strength. Often used as feet, spacers, and vibration dampers, these bumpers absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Mount them on a threaded stud.

Crane Bumpers

Designed to withstand repeated heavy hits on bridge or ceiling cranes, these bumpers protect walls or beams as well as extend crane life.

Fasteners

Abrasion-Resistant Leather Washers

These leather washers are nonmarring.

Oil-Resistant Rubber Sealing Washers

These washers surpass other rubber washers when it comes to withstanding oil, grease, and fuel.

Weather-Resistant Rubber Sealing Washers

Sunlight, ozone, and water won’t affect these washers.

Chemical-Resistant Rubber Sealing Washers

These washers withstand harsh chemicals such as acetic acid and isopropyl alcohol.

Vibration-Damping Snap-In Supports

The ends of these removable supports snap in and compress between panels to reduce vibration of miniature cooling fans in compact electronics.

Routing and Suspending

Vibration-Damping Routing Clamps

A rubber cushion reduces vibration and wear from clamp edges. The cushion also protects lines of pipe, tubing, and conduit from corrosion caused by metal-to-metal contact.

Strut-Mount Vibration-Damping Routing Clamps

Slide multiple clamps into existing strut channel to organize lines of pipe, tubing, and conduit without the need for drilling, welding, or using adhesive. Clamps have a plastic or rubber cushion or body to reduce vibration.

Weld-Mount Vibration-Damping Routing Clamps

For a more secure connection than rail- and adhesive-mount clamps, weld the bottom plate of these clamps onto your rails. They fit tightly around pressurized lines in hydraulic systems to lessen vibration.

Two-Line Weld-Mount
Vibration-Damping Routing Clamps

Secure two pressurized hydraulic lines with a single clamp to lessen vibration in hydraulic systems. Weld the bottom plate onto the mounting surface for a more secure connection than rail- and adhesive-mount clamps.

Rail-Mount Vibration-Damping Routing Clamps

For use with a single line, these clamps mount directly onto rails, no adhesive or welding required. They fit tightly around pressurized lines in hydraulic systems to lessen vibration.

Two-Line Rail-Mount
Vibration-Damping Routing Clamps

Secure two pressurized hydraulic lines with a single clamp. Mount these clamps directly onto rails, no adhesive or welding required. They fit tightly around the lines to reduce vibration.

Vibration-Damping Loop Clamps

A cushion covering the clamp reduces vibration and wear from clamp edges. Clamps surround lines of pipe, tubing, and conduit completely while holding them close to the mounting surface.

Snug-Fit Vibration-Damping Loop Clamps

A molded cushion reduces vibration and wear from clamp edges, plus it provides a tighter fit around material than standard vibration-damping loop clamps.

Washdown Vibration-Damping
Threaded-Rod-Mount Clamping Hangers

These hangers provide maximum corrosion resistance in wet environments and stand up to frequent washdowns with harsh cleaners and sanitizers. Rounded edges, polished surfaces, and acorn or hex nuts that conceal threads reduce the number of places for bacteria to grow and make them easier to clean.

Vibration-Damping
Threaded-Rod-Mount Clamping Hangers

Rubber cushions fit material tightly to reduce vibration and provide a more secure hold than loop hangers. The cushions also protect material from sharp edges and prevent corrosion caused by metal-to-metal contact.

Stackable Vibration-Damping
Threaded-Rod-Mount Clamping Hangers

Connect these hangers to organize multiple lines of pipe, tubing, and conduit. The tight-fitting, santoprene body reduces vibration and prevents corrosion caused by metal-to-metal contact.

Weld-Mount Clamping Hangers

For a strong, secure connection, mount these hangers by welding them to a rod.

Rubber-Cushioned U-Bolts

A durable rubber cushion and mounting plate prevent corrosion and wear caused by metal-to-metal contact. The mounting plate is removable, so the U-bolts can be installed onto an existing line without needing to dissemble it.

Vibration-Damping U-Bolts

Reduce vibration and noise in your lines—a plastic cushion tightly grips pipe, tubing, and conduit to prevent movement. Nylon-insert locknuts grip the thread to resist loosening.

Rubber

Abrasion-Resistant Polyurethane
Rubber Sheets, Bars, and Strips

This polyurethane combines the shock absorbing qualities of rubber with the tear resistance of plastic. Use it for high-tension applications such as conveyor belts, as well as for high-wear applications such as cutting surfaces, bumpers, and liners.

High-Strength Multipurpose Neoprene
Rubber Sheets, Bars, and Strips

This rubber has better shock absorbing qualities and will provide longer life than Standard Multipurpose Neoprene.

High-Strength High-Temperature
Silicone Rubber Sheets and Strips

Greater strength than standard High-Temperature Silicone translates into better shock-absorbing qualities and longer life.

High-Temperature Silicone
Rubber Sheets, Bars, and Strips

High-Strength Oil-Resistant
Buna-N Rubber Sheets and Strips

These sheets and strips offer better shock-absorbing qualities and longer life than standard Oil-Resistant Buna-N.

Bearings

Vibration-Damping Oil-Embedded Sleeve Bearings

With a flexible layer of rubber sandwiched between an oil-embedded bronze bearing and rigid metal shell, these bearings reduce wear and machinery noise.

High-Load Dry-Running Sleeve Bearings

A metal shell adds strength.

Clamp-On Collar Ball Bearings

Quickly secure these bearings onto shafts with the clamp-on collar for a concentric, mar-free hold.

Washdown Clamp-On Collar Ball Bearings

Designed to stand up to frequent washdowns, you can quickly secure these ball bearings onto shafts with the clamp-on collar in food, beverage, pharmaceutical, and chemical plants. The collar centers your shafts and secures them better than set screw ball bearings, which reduces vibration and noise.

Flexible Shaft Couplings

High-Misalignment Vibration-Damping
Precision Flexible Shaft Couplings

Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment.

Set Screw Vibration-Damping
Precision Flexible Shaft Couplings

Each hub includes a set screw, which bites into your shaft to hold the coupling in place.

Clamping Vibration-Damping
Precision Flexible Shaft Couplings

Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft.

High-Speed Vibration-Damping Flexible Shaft Couplings

Use these gear-shaped couplings for high-speed and high-torque applications.

Anti-Slip Adapters for Non-Contact Vacuum Lifters

Stick these adapters onto Non-Contact Vacuum Lifters to create a soft area for your workpiece to touch while it’s in motion.

Contact-Sensing Robot Safety Padding

Cover robot arms and tools with this padding to help prevent injuries in areas where people are working nearby. When the padding is touched, pressure sensors signal your machine to stop moving.
