Plain Bearing Function, Types & Applications Online Solution
In addition to rolling bearings, sliding bearings are the most commonly used in mechanical engineering.
Plain bearings are mainly used when high dimensional and geometric accuracy is required. The bearing shell and shell are firmly seated. Only the shaft or axle rotates in the bearing.

Custom-made plain bearings – materials
Depending on the application, load, speed and materials, plain bearings will adapt to their plain counterpart. Often used materials are copper, tin, zinc and lead alloys, oil impregnated sintered and plastics.
When selecting a suitable plain bearing, care should be taken to ensure below：
• material and grease are matched to each other
• grease completely covers the friction surface
• the material has good damage resistance properties
• the material has high abrasion resistance
• the material has a high thermal conductivity.
Different type of plain bearings
Solid plain bearings: This is the classic plain bearing with oil or grease lubrication. It normally consists of a single bearing material. Plain bearing shells are often made of copper alloys and have oil grooves.
Plastic plain bearing:
•Reduction of maintenance
•No lubrication
•Cutting costs
•Extending the service life
Composite plain bearing – Hydraulic Components
The sliding bushings specially for hydraulic component applications such as gear pumps, piston pumps, vane pumps, compressors and hydraulic cylinders. These metal-polymer composite bearings are most suitable for working conditions with a fluid lubricating environment with high load and high operating speed.
Self-lubricating bushings bearing – Agricultural Machinery
The specific maintenance-free properties of the self-lubricating bearings and wear resistance when used outdoors allow the bearings to be widely used in combine harvesters, planters, belts, sprayers and tractors. The most common components that could be used in self-lubricating bearings are cylinders, linkage and couplings for which oil or grease is difficult to access.
•Bronze (copper-tin alloy)
•White alloy (lead-tin alloy)
•Bearing metal alloyed with lead
•Aluminum alloys
•Plastics (e.g. PTFE)
•Ceramics (to a lesser extent also fiber-reinforced)
•Brass alloys
Choose Your Sliding Bearing Type
Sintered bearings: For example, sintered bushes made of bronze are less tight than solid bushes. The lubricant can collect in the pores (mixed friction). During operation, an oil film collects between the bearing and the shaft. Sintered bronze plain bearings are usually corrosion-resistant, highly thermally conductive and antimagnetic.
Lubrication of plain bearings
Simple plain bearings: They are unlubricated or lubricated with grease.
Check out where sliding bushings have been used in real-world applications around the world from a wide range of industries, from combine harvesters to rollercoasters, from hot-air balloons to light aircraft.
Plain bearing application example
-Injection plastic machinery
We brought self-lubrication concept into plastic machinery field in China and started to supply bushings to the world injection plastic machinery manufacturers. The low friction, high load and long lasting features of the maintenance free bearings provided a reliable guarantee for the relative machines.
-Press & Forging Machinery
Plain bearing is commonly used for rotating and sliding worktable parts of machine tools, providing good guidance and maintenance-free self-lubricating operation guarantee for the machines. Its low friction and optimized performance provide a considerable cost saving and at the same time, improves the noise level of the machines during the operation.
-Hydro Power Projects
This kind of bearing can be applied under dry, high temperature, high pressure, corrosive, water or other chemical environments when no oil can be introduced. It is widely used in automotive products line, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in metallurgy industry, mineral machines, ships, turbo generators, hydraulic turbines and injection moulding machines.
