Rupture discs and burst discs are designed to open and relieve overpressure, high temperature, or vacuum conditions at a predetermined differential pressure or specific temperature. They may be thermally or mechanically actuated

Abrasive discs consist of abrasive grain adhered onto the surface of a cloth, film, paper, non-woven or other backing. They are used for metal removal, surface finishing, sanding, etc

Solid phase extraction (SPE) cartridges and discs are used to clean up a sample before using a chromatographic or other analytical method to quantify the amount of analyte(s) in the sample

Flap wheels and specialty abrasives includes cartridge rolls, cross pads, sleeves, unitized or convolute wheels, interleaved flaps, flap discs and other specialized abrasive products converted from coated or nonwoven abrasives

Rotating biological contactors are large discs on rotating shafts that are mounted in wastewater tanks, but only partly submerged. As the discs turn, the microorganisms on them repeatedly contact both air and the organic substances in the water

Superabrasives and diamond wheels consist of grinding wheels, abrasive saw blades, wheel dressers, single point tools and other products utilizing diamond or cubic boron nitride (CBN) abrasive grain.

Rotary encoder disks are round or disk-shaped and have evenly-spaced holes or markings around their perimeter.

Grinders and grinding machines use an abrasive that is bonded to a wheel, belt or disc to remove material and improve surface finish

Buffs, bobs and buffing wheels are used to hold finishing compounds and polish parts made of metal, plastic, ceramic, glass, wood, stone, silicon, or optical materials.

Sanders and sanding machines are used to finish wood, plastic or composites through the application of abrasive belts, discs or sheets

Nonwoven surface conditioning abrasives consist of abrasive grains adhered with resin to the internal fiber surfaces of a nonwoven textile backing.

Tool turrets are indexing tool holders for lathes, transfer machines, and other machine tools. They allow equipment to carry multiple cutting tools at one time and mount individual tools in the correct sequence.

Abrasives and abrasive products are used to remove surface materials such as metal, ceramics, glass, plastics, and paint. Abrasives and abrasive products include discs, belts, blast machines and sandblasters, as well as sheets, rolls, and hand pads

Process dryers are used to remove liquids or moisture from bulk solids, powders, parts, continuous sheets or other liquids by evaporation or sublimation.

Data storage media is used to record and store large-scale data from computer systems.. Examples include optical disks and magnetic tapes.
