There are no special materials which have low difference of thermal expansion and similar physical properties with the given materials of bearings. The self-lubricating materials used at high temperature are currently in the state of laboratory research stage, and have not been prepared for bearings at large production scale. Bearings treated by electroplating, magnetron sputtering and liquid spraying are used at the temperature lower than 200°C. However, there are no bearings that have the continue self-lubricating performance from room temperature to 800°C, though the coating made by powder sintering, supersonic thermal spraying and cold spraying. The sliding bearing materials are generally copper alloys, aluminum alloys and tin alloys. These metal materials have an ability of excellent plastic deformation during the formation of coating by cold spraying.

Motion system designers are increasingly outfitting round and profile rails with self-lubricating bearings that can significantly, reduce cost of ownership, improve performance and deliver virtually maintenance-free operation. However, whether they will deliver their fullest potential, depends on how the bearings have been specified, installed and evaluated for compatibility with their intended environment.

The production efficiency of inlaying solid lubrications is low, which cannot satisfy the requirements of large-scale mass production. The work temperature of socket bearings in the missile launcher mechanism is higher than 800°C. Materials such as resins used as components in dope coating cannot be operated under ultra-high temperature conditions. At present, the maximum working temperature of grease-based lubricating materials generally do not exceed 200°C, and the maximum using temperature of polymer-based self-lubricating materials (single-phase) generally does not exceed 400°C . The ranges of optimum lubrication for single-phase materials are shown in Table 1. Self-lubricating coatings are mainly composed of solid lubricating fillers such as MoS2, PTFE, WS2, graphite, and some additives such as polyimide, epoxy resin, phenolic resin, leveling agent, dispersing agent, defoaming agent, etc. Gao used PAI (polyamide-imide polyamide-imide) as a binder, and the coating prepared by mixing 8% MoS2, 5.4% PTFE and 1.5% graphite had the best performance. The coating had not changed which was tested at 80°C and −40°C, and it was not changed for socking in 10% HCl over 3 months .

Bearings with self-lubricating properties at different temperature conditions are still very rare. Compared with the advanced bearings of European and North American, the sliding bearings of China have short life, low carrying capacity, poor self-lubricating performance and overcapacity. High-performance sliding bearings such as, self-lubricating, high-load, and long-life are relied on import. The lack of high-performance sliding bearings restricts the development of China’s basic manufacturing industry, especially the military industry. Therefore, the self-lubricating performance of the sliding bearing during in wide temperature range should be improved, and the different lubricating methods for different bearings at different temperature should be selected. As shown in Figure 2, the sliding bearing damage quickly due to the lacking of self-lubricating properties of bearing, and the mixed lubrication and even dry contact friction at the start-stop stage of engine . Therefore, researching and improving the friction mechanical properties of the bearing under dry friction conditions is one of the key technologies for improving the bearing life of at start-stop stage.

Other important uses for copper and copper-base PM materials include friction materials, electrical parts, filters, additives to iron, aluminum powder alloying, catalysts, paints, and pigments. Lubricants are available in many forms, from hard, highly viscous lubricants that are the consistency of frozen butter to lubricants with a low viscosity, an example of which is paraffin. Lubricants are normally considered oils, but these, along with greases, are the more common types. More specialist lubricants could be any material that can be inserted between the two sliding components.

These linkages usually have felt, or more rarely, leather bushings. Ceramic bearings are very hard, so sand and other grit that enters the bearing are simply ground to a fine powder that does not inhibit the operation of the bearing. Known as jewel bearings, these bearings use jewels, such as sapphire, ruby, and garnet. The distance from one parting edge to the other is slightly larger than the corresponding distance in the housing so that a light amount of pressure is required to install the bearing. This keeps the bearing in place as the two halves of the housing are installed. Finally, the shell’s circumference is also slightly larger than the housing circumference so that when the two halves are bolted together the bearing crushes slightly. This creates a large amount of radial force around the entire bearing, which keeps it from spinning. It also forms a good interface for heat to travel out of the bearings into the housing. Sleeve bearings of inch dimensions are almost exclusively dimensioned using the SAE numbering system. The numbering system uses the format -XXYY-ZZ, where XX is the ID in sixteenths of an inch, YY is the OD in sixteenths of an inch, and ZZ is the length in eighths of an inch.

They offer JDB solid lubricant inlaid bearings made of copper alloy with casting methods.

The FR bronze self lubricating bearing has phosphorous, bronze and meshed backing with PT. The FU sintered bearing with oil is sintered under high temperature, and oil is soaked into the metal under vacuum. There are three types of self-lubricating plain bearings used today. Oil-filled sintered bronze bearings were first conceived in the 1930s, with self-lubricating metal-polymer bearings developed around 1950 and lubrication-free solid polymer bearings appearing in the 1960s.

The solid lubricant fills the open space in the bearing and constantly provides uniform lubrication. VPL solid lube never requires re-lubrication during the life of the bearing. The self-lubricating features allow bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds. Plug graphite bearings are primarily used in applications that need continual lubrication in hard to reach areas. Graphite is mechanically forced into the holes/grooves under extreme pressure. A film of lubricant is transferred to the shaft as it begins to turn. These bearings offer continuous lubrication over long periods without maintenance. Get better self-lubricating bearings price rates to reduce your costs.
