Mechanical brake and clutch assemblies consist of elements for both the connection and disconnection of shafts (clutch) and for the slowing or stopping of shafts (brake) in equipment drives.
Traction coatings and friction modifiers control the friction, binding or adhesion between two surfaces.

Brake Controllers

(35 companies)
Brake controllers are used to control braking systems. They can simply engage and disengage the brake, or control the speed of engagement, breakaway torque, and other variables.

Press Brake Tooling

(28 companies)
Press brake tooling includes dies and punches used with a press brake to form, bend or flatten sheet metal.
Friction stir welding (FSW) tools are refractory alloy or carbide-shouldered cylinders with a central pin or probe, which is rotated at high speed and pressed against the seam of two abutted metal substrates. The frictional heat forms a solid-state weld without melting the base metals.

Press Brakes

(278 companies)
Press brakes are used to bend and fold metal by pressing it into a die.
Dynamic braking resistors (DBRs) produce braking torque and absorb the high amounts of energy generated by stopping electric motors. They are used in variable-speed drive systems such as elevators, cranes, and trains.

Dynamometers

(91 companies)
Dynamometers are used in motor and engine testing. These devices apply braking or drag resistance to rotation, and measure torque at various speeds and power input levels.

Washers

(1,216 companies)
Washers are disks of metal or non-metallic material placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevent leakage, isolate, prevent loosening, or distribute pressure.

Air Bearings

(37 companies)
Air bearings use a thin film of pressurized air to support a load. They do not generate friction.
