Bearing Surface Material

|
|
| ||
| Bearing Surface Material: | |||
| Your choices are... | |||
| Bronze - Sintered | Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient. | ||
| Graphite / Metal Alloy | Bearing surface is an alloy manufactured from molten graphite and metal. This material is self-lubricating. | ||
| Plastic | Any of numerous organic, synthetic, or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments. Common plastic materials include Acetal, Nylon / Polyamide and PTFE / Teflon. Nylon Nylon, comprising several grades of polyamides, is a general purpose material in wide use; it is tough and resistant and has good pressure ratings. PTFE PTFE (polytetrafluoroethylene) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers. Acetal Acetal polymers are semi-crystalline. They offer excellent inherent lubricity, fatigue resistance, and chemical resistance. Acetals suffer from outgassing problems at elevated temperatures, and are brittle at low temperatures. Glass filled, and added lubrication grades are available, flame retardant grades are not. Brand names include Celcon (Hoechst Celanese), Delrin (Dupont), Thermocomp (LNP), Ultraform (BASF), and Acetron (DSM). | ||
| Wood | Oil-impregnated hardwood often used in agricultural applications. | ||
| Other | Unlisted, unspecified, or proprietary material. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Lined Bearing? | Bearing surface and body material do not have to be the same. Lined bushings / sleeve bearings have a lining on the bearing surface. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

Additional Specifications

|
|
| ||
| Self-lubricating / Oil Impregnated? | Bearing is self-lubricating and does not require any external lubrication. Sintered bronze can be impregnated with oil. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Extreme Environment? | Bearing can withstand and function within hostile or extreme environments, including high or low temperature, humidity, shock, vibration, etc. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Operating Temperature: | This is the full required range of ambient operating temperature. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
