Sanding Wheel Brushes with Shank

Wheel Brushes with Shank

Remove light-to-medium rust and stains and small burs with these flexible-bristle brushes.

Low-Scratch Wheel Brushes with Shank

Use on delicate surfaces.

Aggressive-Cleaning Wheel Brushes with Shank

Rigid, partially twisted bristles handle tasks such as edge rounding and removing weld slag, heavy surface contamination, and large burs. Also known as knot-wire brushes.

Nonsparking Wheel Brushes

Made of phosphorus bronze that is Factory Mutual approved, these brushes inhibit sparking and are nonmagnetic and corrosion resistant.

Low-Scratch Wheel Brushes

Use on delicate surfaces.

Long-Lasting Fast- and
Aggressive-Cleaning Wheel Brushes

A mounting nut on each side of the arbor lets you use both sides of the brush.

Fast- and Aggressive-Cleaning Wheel Brushes

The bristles are twisted all the way to the end so they’re more rigid and clean fastest.

Nonsparking Aggressive-Cleaning Wheel Brushes

Made of phosphorus bronze that is Factory Mutual approved, these brushes inhibit sparking and are nonmagnetic and corrosion resistant.

Long-Lasting Aggressive-Cleaning Wheel Brushes

Bristles are partially twisted in alternating directions, which prevents them from separating.

Sanding Wheel Brushes

Long-Lasting Sanding Wheel Brushes

The abrasive lasts longer than that of standard brushes.

Building and Machinery Hardware

Load-Rated Threaded-Stud Bumpers

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.

Threaded-Stud Bumpers

Twist these bumpers into a threaded hole. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces.

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.

Light Duty Leveling Mounts with Threaded Stud

Meant for light duty applications, these mounts are not rated for capacity.

Disc Springs

Wave Disc Springs

Use these high-carbon steel springs in noncorrosive environments.

Stacked Wave Disc Springs

Multiple rows of waves allow these springs to handle higher loads than standard wave disc springs.

Split Wave Disc Springs

A gap allows these springs to compress without widening, so they won't bind or deform when used inside a housing with tight clearance.

Belleville Disc Springs

Use these steel springs in noncorrosive environments.

Belleville Disc Springs for Ball Bearings

Install these springs, also known as bearing preload washers, against ball bearings to reduce noise and unwanted movement along the shaft.

Belleville Disc Springs for Flange Bolts

Keep pipe flange connections sealed during demanding applications. When installed under flange bolt heads, these springs compensate for shock loads, vibration, and thermal expansion and contraction.

Curved Disc Springs

Use these high-carbon steel springs in noncorrosive environments.

Finger Disc Springs

Raised tabs, known as fingers, enable these springs to compress without widening, so they won't bind or deform in housings with little clearance. Use with ball bearings in precision and high-speed drive assemblies to reduce noise, vibration, and wear.

Steel Wire Cloth Discs

These discs are die cut to an exact diameter with smooth edges for use in tube, pipe, and duct.
