Ballasts
(403 companies)
Ballasts are electrical devices that condition the line voltage (amplitude, amperage and waveform) to operate fluorescent and HID lamps. Basically they serve two functions: to provide the starting kick, and to limit the current to the proper value for a particular lamp.
LED Lamps
(773 companies)
LED lamps are light emitting diode arrays with traditional lamp ballasts.
Ball Bearings
(717 companies)
Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings.

Plastic Sheet and Plastic Film
(843 companies)
Plastic sheet and plastic film are flat pieces of plastic formed to a precise thickness for use in specific applications. Products differ in terms of chemical systems, properties, and dimensions.
Crystals
(406 companies)
Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency. Quartz, a piezoelectric crystal that provides excellent mechanical and electrical stability, acquires a charge when compressed, twisted, or distorted.
Minerals, Aggregates, and Sands
(406 companies)
Minerals, aggregates and sands consist of bulk or particulate forms of silicates, clays, calcium carbonate, wollastonite, aggregates and other additives used to extend, fill, strengthen or modify plastics, coatings, adhesives, and other materials.
Washers
(1,164 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.

Screens
(130 companies)
Screens consist of a surface with openings of specific sizes. They may be made in many ways, including perforating a sheet, weaving metal wire or synthetic fibers or electroforming. Among other uses, screens are commonly used to provide open but secure separation for a clean environment and flying objects, debris or insects.
