Daemar Inc. manufactures powdered metal bushings, solid metal bushings, and plastic bushings. The metal bushings are formed from bronze and iron, while the solid metal bushings are for high-load, low-speed applications. Lubrications for the metal bushings include solid PTFE, graphite, self-lube and oil grooves. The company's plastic bushings are used for light, maintenance-free applications.

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.

igus produces maintenance-free, plain, plastic bearings that come in more than 8,000 imperial and metric sizes and are lubrication-free, waterproof, and suitable for temperatures up to 482 degree Fahrenheit. The most popular styles include the M250 which has a coefficient of friction of 0.1 to 0.3, PSI of 2,901, maximum PV of 3,400, and is high-impact resistant. Others include the iglide J (chemical-resistant), R (low moisture absorption), A200 (abrasion-resistant), G300 (vibration-dampening), and L280 (for soft shaft materials). The company also manufactures Drylin linear bearings and iglubal spherical bearings.

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.

Spadone-Alfa offers plain bronze bushings, self-lubricated bronze bushings, graphite plugged bushings, and carbon/graphite bushing inserts. The bronze bushings are offered in a wide variety of copper alloys, such as Aluminum (CDA 954), Manganese (CDA 863), and Bearing Bronze (CDA 932), in over 900 sizes. The self-lubricated option comes as MET 70, an oil-free, self-lubricating insert that fits Spadone-Alfa's 200 Series Pillow Blocks and Flange Units. These inserts are made of carbon/graphite material and are available in two temperature ranges: up to 500 degrees Fahrenheit, and up to 1100 degrees Fahrenheit.

National Bronze Manufacturing Company makes a variety of bronze bushings, including king pin bushings, bowl bushings, CB bushings, leaf spring bushings, spring eye bushings, PM bushings, and brass bushings. The company's standard lines of bronze bushings are stocked either with internal grease grooves (Spira-Lube style) or without (plain bore).
