Oilless bearings come with solid lubricant to form a permanent layer of solid lubrication film on the surface. The friction coefficient of bearings is smaller, the wear-resisting degree is higher, the service life is longer, and there is basically no need to add lubricating oil in use.
Traditional bearings can not leave the lubricating oil when they work. Once the oil is broken, the loss will increase rapidly, the maintenance cost is high and the application field is limited.

What is self-lubricating bearings?
There must be bearings in the machinery in a broad sense to ensure the normal operation of the machinery.Bearings can be roughly divided into rolling bearings and sliding bearings.
General sliding bearings will burn and bite due to high load, motion form, foreign body mixing, temperature conditions, oil supply and poor maintenance.
Self-lubricating bearing refers to the sliding bearing that “can reduce the amount of oil supply, the number of oil supply” or “can be used in the case of no oil supply”.Even in the general sliding bearings can not maintain the performance of the harsh conditions, self-lubricating bearings can also play the required performance of the bearing with its wear resistance and burn and bite resistance characteristics, achieve high mechanical performance, and without maintenance, so it is widely used in a variety of fields.
Our bearings feature self-lubricating functions and demonstrate high performance, which normal plain bearings cannot provide, for fluid lubrication, boundary lubrication, and dry friction fields.

Self-lubricating bearings characteristics
- No oil supply device, oil supply hole, oil groove processing
The cost of oil supply device, processing fee, assembly fee and other redundant costs and time savings, from the manufacturing cost can be greatly reduced.
- The reduction of operating costs
Significantly reduce the use of lubricating oil and equipment maintenance costs, and reduce the use cost.
- No maintenance
Can greatly reduce the oil supply and oil supply device inspection and other maintenance costs.At the same time, it will not cause problems due to poor oil supply.
- Reduce design time
Oil-free can greatly simplify design and structure, and greatly reduce costs and practices.In addition, the durability of self-embellishing bearings is excellent, which can achieve high performance and long life of machinery.
- Lubricating oil recovery and environmental protection
No need to waste oil recovery treatment, conducive to environmental protection.
Select the right bushing for the application
The products are widely used in industrial machinery such as automobile, railway rolling stock, OA/ information communication equipment, civil construction, dam and other fields that need to be used without maintenance for a long time, as well as in the space and ocean development fields that have high performance requirements under harsh environment.
Metal bearings typical application
Oilless bearings products are closely linked to social infrastructure and support the peace of mind, safety and comfort of life.
- Â Machines with oscillating or reciprocating motions or start and stop frequently, where lubricant film is seldom produced
- Â Hot or cold facilities where lubricating oil is not as effective
- Facilities that cannot be lubricated for reasons of environmental protection
- Facilities with large loads or moving at low speed where a lubricating oil is not as effective
- Home electrical apparatus and office automation, which are easily affected by oil adhesion or leaks and do not accept lubrication
- Machines subject to penetration of foreign matter or used under severe conditions where normal plain bearings do not offer satisfactory wear resistance
- Eco-friendly clean energy facilities
- Automobiles, factory automation machines, and food machinery, which should be used under maintenance-free conditions without the need for lubrication for long periods
