Energy Generation
Oil-free lubrication bearing, as the name implies, refers to the use of before or during the use of lubricants can also be normal operation, and play a good effect of friction reduction bearings. Oil-free lubrication bearing belongs to a kind of sliding bearing. General sliding bearings need to add lubricant, grease and other lubricants before work, so as to form a lubricating film on the friction surface and play an effective role in lubrication, while oil-free slide bearings made of self-lubricating materials or pre-filled with lubricant after sealing up can be used for a long time, without adding lubricant during the work process.
Bushing Type
Oil-free lubrication bearing from the product structure is divided into solid inlay bearing, composite bearing, oil bearing, new single lubrication material.
Solid inlay bearings
Common is the solid lubrication material graphite (black lead), polytetrafluoroethylene (PTFE), molybdenum disulfide, etc. using the inlay process buried in high force brass, tin bronze, aluminum bronze, cast iron or GCr15 and other alloy materials. It breaks through the limitations of general sliding bearings relying on oil film lubrication. In the process of use, the solid lubrication is made to rub with the shaft through frictional heat, forming the excellent condition of oil and powder coexisting lubrication, which not only protects the shaft from wear, but also makes the solid lubrication characteristics eternal. The hardness of high force brass is twice as high as the general brass bushing, and the wear resistance is twice as high, and the bearing capacity is high.
Composite Bearings
The common composite bearing is made by combining two layers of steel plate and copper powder layer (bimetal), or three layers of steel plate, copper powder layer and self-lubricating material (PTFE, PEEK, POM) + filling material. It adopts high temperature sintering process to bond the self-lubricating material on the steel plate, which not only ensures the frictional wear performance of the working surface of the product, but also ensures the structural stability and load-bearing capacity of the bearing.
Oil-bearing
Oil-containing bearings are made of metal materials, and the bearings are oiled and sealed with lubricating oil, so that they can be used without adding oil to achieve the effect of “self-lubrication”. Since the bearing contains oil lubricant, it has good lubrication and avoids oiling and maintenance work.
New Single Lubricant Bearings
New single-lubricated material bearings are common resin, ceramic, tungsten carbide bearings, etc., and new materials are constantly being developed, but these bearings may have high costs, narrow application area, etc., can not be widely promoted to replace rolling bearings.
Bearing Bushing Advantage
Oil-free lubrication or oil-less lubrication, is suitable for places where it is impossible or difficult to refuel, can be used without maintenance or less maintenance, and also eliminates the risk caused by insufficient oil supply.
No oil supply device required
No oil supply device is required, and oiling can be eliminated during operation, thus saving significant installation and operation costs. Oil-free can make the design and structure, etc. significantly simplified, reducing costs and saving design time.
Green and Environmentally Friendly
No need for waste oil recycling treatment, which is good for environmental protection.
Reduced requirements for grinding parts
The hardness requirement for grinding shafts is low, and shafts without tempering treatment can be used, thus reducing the difficulty of machining related parts.
High and low-temperature resistance
High and low-temperature resistance, some products can be used at temperatures from -200℃ to 600℃.
Applications

Failure mode
Abrasive particle wear
Some of the hard particles that enter the bearing gap rotate with the shaft and act as abrasive to the bearing surface.
Scratching
The hard particles entering the bearing gap or the rough microscopic contour spikes on the surface of the shaft diameter scratch the bearing surface with linear scars.
Gluing
When the transient temperature rise is too high, the load is too large, when the oil film rupture or insufficient oil supply, bearing surface material adhesion and migration occurs, causing bearing damage.
Fatigue spalling
Under the repeated action of the load, the bearing surface fatigue cracks perpendicular to the sliding direction, after the expansion of the bearing material spalling
Corrosion
Lubricant in use constantly oxidation, the acid generated on the bearing material has corrosion, material corrosion is easy to form pitting spalling. There is also cavitation fluid erosion electric erosion.
Feature Description

Liquid lubrication conditions, isolated lubricant does not directly contact the sliding surface for impact absorption.
Self-lubricating bearings advantages and characteristics.
Self-lubricating bearings are also widely used, such as tobacco machinery, automobiles, printing presses, micro-motors, textile machines, motorcycles and agricultural and forestry machinery and so on. Self-lubricating bearings have their own advantages and characteristics.
1, there is a moderate amount of elasticity, can distribute the stress in a wider contact surface, to improve the bearing capacity.
2, self-lubricating bearings have good wear resistance, small coefficient of friction, long service life.
3、No oil lubrication or less oil lubrication, suitable for places where it is impossible to refuel or very difficult to refuel, can be used without maintenance or less maintenance.
4, static and dynamic friction coefficient is similar, can eliminate the crawling at low speed, so as to ensure the working accuracy of the machinery.
5, self-lubricating bearings for grinding shaft hardness requirements are low, without tempering treatment of the shaft can be used, thereby reducing the processing difficulties of the relevant parts.
Self-lubricating bearing
6、Self-lubricating bearings can form a transfer film during operation, which can protect the shaft of the grinding, no bite shaft phenomenon.
7、It can make the machinery reduce vibration, reduce noise, prevent pollution and improve labor conditions.
8、Thin-walled structure, light weight, can reduce the volume of machinery.
9、The back of the steel can be plated with a variety of metals, can be used in corrosive media; has been widely used in the sliding parts of various machinery, such as.
Printing machines, micro-motors, textile machines, tobacco machinery, automobiles, motorcycles and agricultural and forestry machinery, etc..
But the greater the starting friction. The shaft part of the bearing is called the shaft diameter part, called bush and shaft diameter together to go. In order to improve the casting of the inner surface layer of the friction material of the friction bearing surface properties called bearing lining.
Bearing and bearing lining materials are collectively referred to as bearing materials. Bearing applications are generally in low speed and heavy conditions under loading conditions, maintenance and lubrication or difficult operating areas.
POM type bearing bushing material
POM type material is filled with tetrafluoro-modified polyacetal plastic as the surface layer of the three-layer composite self-lubricating material, it is a benign boundary lubrication material, so it is especially suitable for high load and low speed under the rotary motion, swing motion and often under load opening and closing and not easy to form hydrodynamic lubrication of bearings, thrust washers, sliders, ball seats and other friction parts.
POM Bushes can make full use of trace amounts of grease and can be maintained for a long time without oiling under boundary lubrication lubrication conditions. Under completely oil-free lubrication conditions, POM Bushes have lower frictional performance and allowable PV values, so they are usually rolled out on the plastic surface with oil storage pits and coated with lithium-based lubricating grease or silicone grease during assembly.

FASTER – BETTER – SAFER
POM composite bushing, Bronze sliding bearings, composite bushings and engineering plastics: POM bearings. With the exception of the sliding layer, composite bushings can be machined using conventional methods.
If the bushing is required to have a smaller width than the standard size, this can be easily achieved by turning. It is also possible to drill lubrication holes. However, any burrs, especially on the sliding surface, must be removed.
Strips can be bent, pressed, cut or drilled to suit individual applications. When cutting or drilling, we recommend doing so from the sliding surface side to avoid creating burrs on the sliding layer.
Any metal surfaces exposed as a result of machining should be protected to prevent corrosion.
Machining the bore of PTFE composite bushings
The PTFE composite bushing is ready for installation. Any adjustment to the bore (i.e., sliding surface) will reduce the life of the bushing and should only be done in special circumstances. If it is necessary to machine the bore, it should be resized and calibrated.
Machining the bore of POM composite bushings
Bushings made of POM composite are ready for installation. However, if necessary, the bore of the bushing can be machined to size while mounted in its housing.
