...grease, and water and oil splash. Material. Since v-ring seals are made completely from rubber, they are easy to install. They are low-friction and elastic enough to be stretched over flanges and other assemblies for positioning depending on size...

Industrial Winches

...or pneumatically. Friction winches have two grooved drums arranged in-line to run the line using friction and a larger drum to reel in the rope for storage; the crushing pressure of the running rope under tension is taken by the grooved drums directly...

Magnetic Bearings

(14 companies)
Magnetic bearings use an electromagnet to provide noncontacting, friction-free motion in rotary applications.


(1,332 companies)
A screw is a wide-encompassing type of hardware fastener that attributes its mechanical capabilities to the helical groove that extends around the circumference of the device's shank. These threads provide the friction and traction that serves a screw's purpose: to assemble or position two workpieces in relation to each other. While used synonymously, screws and bolts are not mechanical clones.
Jewel bearings, jewels and pivots are miniature components used in instruments and controls requiring low friction, long life and non-magnetic properties.
...engagement. Noncontact technologies use magnetic fields and eddy currents.   Friction torque limiters use the friction between contact surfaces to transmit power. This is the most common configuration. Toothed clutch engagement uses toothed contact...

Thrust Washers

(54 companies)
Thrust washers are used as a bearing surface for rotary applications. They are usually made of steel, bronze, plastic, or other material with low friction coefficients.

Mechanical Brakes

(183 companies)
Mechanical brakes convert kinetic energy to other energy forms, primarily heat. They decelerate shafts and linked components via friction between a rotating body and wear-resistant material.
...to a forging temperature, the current is interrupted. The heat and pressure bring forth coalescence. Types of Frictional/Fusion Welding. Friction welding is a forging technique relying upon the heat created from friction between a moving workpiece...
Solid and dry film lubricants form a dry layer or coating that excludes moisture and reduces friction, binding, and wear. They often contain additives such as corrosion, oxidation, and rust inhibitors.

Bearing Rollers

(18 companies)
Bearing rollers are the functional components of friction-reducing roller bearings. Common types of bearing rollers are tapered rollers, cylindrical rollers, spherical rollers, needle rollers, cam follower rollers, and rollers for crossed roller bearings.

Ball Splines

(32 companies)
Ball splines provide nearly friction-free linear motion while simultaneously transmitting torsional loads. The path of the bearing balls is straight, not helical, which allows for a very efficient coupling device suitable for a variety of applications.

Slurry Pumps

Choices may also include ethylene propylene (EPDM), a plastic that offers good resistance to sunlight, weathering and ozone; and polytetrafluoroethylene (PTFE), which exhibits a high degree of chemical resistance and low coefficient of friction...
Medical cable assemblies are designed to connect medical and laboratory instruments and equipment. They transmit power and/or data and usually have an abrasion-resistant jacket that provides relatively low surface friction and mechanical durability. Many are designed with a high degree of flexibility to avoid kinking, and temperature-resistance to withstand autoclave sterilization. Some are disposable.
Plastic and rubber balls are rolling, spherical elements that have low friction values and require little or no lubrication. They are lighter than metal balls and resistant corrosion and abrasion. Some plastic balls resist high temperatures, but others do not. Rubber balls are characterized by a high degree of flexibility and elasticity.
