Graphalloy manufactures five different types of bushings and bearings, produced in a complete and standard size range. The general purpose bushing is available in FDA accepted grades and works in temperatures up to 750 degrees Fahrenheit, while the high temperature bearing can provide service upwards of 1,000 degrees Fahrenheit and is self-lubricating (i.e. no oil). The company also makes flange type bushings for radial and thrust loads, block type bushings for submerged applications, and split double flange bushings for harsh environments.

The Pacific Bearing Company offers linear sleeve and flanged bearings, closed and open bearings, and closed ball bearings in both regular and wide ball sizes. Pacific Bearing linear sleeve and flanged bearings are made from anondized aluminum shells (or optional 316 stainless steel) and a Frelon liner. They can tolerate temperatures of -400 degrees to 400 degrees Fahrenheit. Pacific Bearing also manufactures plain polymer and compound polymer bearings, which are made from a thermoplastic compound made of PEEK polymer matrix, reinforced with synthetic fibers and modified with triboadditives. Check out their LAT linear actuator technology and their downloadable catalog.

Quality Bearings & Components (QBC) distributes Thomson products, including Thomson's Super Smart, Super, and Precision Steel Ball Bushing Bearings in both open and closed types. These products offer a coefficient of friction as low as 0.001. In addition, the Super Smart Ball Bushing carries up to 6x the load capacity, or 216x the travel life, of conventional linear bearings. QBC also carries sintered bronze sleeve bearings in five different series: small, standard, ultraprecision, plastic, and Frelon-lined.

IDA Motion offers a wide range of ball bushings in both European and Japanese metric sizes, as well as flange and double-length flange ranges. It also sells Minuteman Self-Lub/Teflon Composite Bearings, that are made of 300 stainless steel ceramic coated aluminum, can run on both hardened and soft shafting, and have a coefficient of friction between 0.09 and 0.12. The company offers a ceramic coated bearing, as well, with a coefficient of frcition between 0.04 and 0.08.
