Oilite Plus is the same bronze alloy as an Oilite, impregnated with turbine oil and fine particles of polytetrafluoroethylene (PTFE). This reduces the friction by approximately 17% versus standard Oilite material. This material is usually used in applications that exhibit mixed-film or boundary condition lubrication.
[citation needed] Powdered metal sintered bearings (in the case of roller chain, the bushes) are self-lubricating because their porosity is impregnated with lubricants during the manufacturing process. In use, frictional heat causes the lubricant to expand and flow out of the pores, forming a film between mating parts.
The handle is composed of a fire anodized titanium frame, oil impregnated bronze bushings, an oversized pivot screw 0.19 in (0.48 cm) in diameter, and a textured G10 glass-reinforced plastic scale with an incorporated backspacer. [3] The NATO Stock Number for the SMF knife is 1095-01-531-5015. [4]
A pillow block bearing (or plummer block) is a mounting used to support a rotating shaft with the use of bearings and various accessories. The assembly consists of a mounting block which houses a bearing. [1] The block is mounted to a foundation, and a shaft is inserted, allowing the inner part of the bearing/shaft to rotate. [1]
A double-tapped bushing, commonly shortened to bushing, is a fitting which serves as a reducer. It is a sleeve similar to a close nipple, but is threaded on both its inner and outer circumferences. Like a reducer, a double-tapped bushing has two threads of different sizes.
In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it. Bushings are typically made from porcelain, though other insulating materials are also used.
