The properties of thin film made by magnetron sputtering is excellent, however, the production efficiency is too low due to the vacuum and deposition process. The large-scale size of bearings such as bearings used in ship diesel engine cannot be deposited due to the structure limit of magnetron sputtering machine. The porosity of bearing made by powder sintering is high, and the alloys are oxidized at the high sintering temperature. Most of the sliding bearings have not been surface treated, and these bearings have high dry frictional coefficients, low fatigue strength, low life and low bearing capacity. The frictional coefficient of copper alloy, aluminum alloy and tin alloy of sliding bearings is generally higher than 0.5 under dry friction condition, and it does not have self-lubricity under a wide temperature range. The traditional copper alloys of sliding bearings contain Pb metal, which is polluting and harmful to human. The self-lubricating materials at ultra-high temperature are still in the laboratory research stage, and the sliding bearing with self-lubricating cannot be produced on a large scale. The most advanced surface treatment method available today is the surface spraying coating method. Spraying sliding bearings are characterized by high speed and high efficiency. It takes only several seconds to spray lubricating liquids, and large-scale and large-scale production will be realized if solidification furnaces and cooling furnaces are enough.

As used herein, the term “bearing” refers to at least one of two engaging members movable relative to one another. Thus, a bearing can be in any configuration such as a sleeve bearing, a spherical or ball bearing, a flat surface, etc. The contacting member which engages with the coating on the bearing does not require any special coating or treatment, however, a steel polished surface such as a 5 to 8 microfinish is recommended. In order to reduce the number and size of voids in the final product, the curing may take place under increased pressure. Pressures in the range of about 100 to about 130 psi may be suitable. The product should be left in these conditions until it is cured. The polymerization reaction occurs at a temperature which will vary depending on the amount of inhibitor, initiator, and accelerator in the mixture.
The clearance limits must be adjusted for any closure due to press fit by adding the maximum interference to the limits of clearance. These adjusted values will normally permit adequate running clearance after assembly for static to slow speeds and intermediate to heavy loads. LUBRON AQ bushings may require larger clearances for special conditions. For severe or special conditions, please consult a LUBRON engineer. The outside diameter of a bushing is dependent on the required wall thickness and size of the housing bore. To determine the outside diameter, add twice the recommended wall thickness of the inside diameter of the bushing. The following Tables provide the recommended wall thickness for LUBRON AQ bushings.

The development, manufacturing and processing capabilities of sliding bearing materials of China should be improved. At present, the main production technologies sliding bearings are centrifugal casting and alloy powders metallurgical. However, most bearings have no surface lubrication and will be quick broken. For example, more than 90% of the bearing bushes prepared by powder metallurgy in the automotive industry are not subjected to surface self-lubricating treatment such as electroplating and magnetron sputtering. Powder metallurgy technology of sliding bearing preparation has high production efficiency and low cost. The sliding bearing prepared by metallurgical process has high porosity without centrifugal force. In addition, the bearing alloys such as copper, aluminum and tin are easily oxidized at high temperature during the metallurgy preparation of sliding bearing, and metallographic organization is not uniform . Centrifugal casting is another common production process for sliding bearings. The integral and thick-walled plain bearings are usually produced by centrifugal casting. While some of the earliest self-lubricating bearings were developed by Chrysler the earliest self-lubricating chains were bushed chains, which consisted of pins, plates, and sintered bushes.

It is the best choice for the bushes of various kinds of engineering application. Various size and catagory available as per customer requirement. While these systems may be temporarily “self-lubricating”, the lubricant will eventually be used and need to be replaced. Many “lubed for life” bearings are not really lubed for life, they are simply “lubed for a long time”. Self-lubrication is characterized by the bearings ability to transfer microscopic amounts of material to the mating surface. This transfer process creates a film that provides lubrication and reduces friction over the length of the rail or shaft. Self-lubrication has several advantages over traditional lubricated bearings. Self-lubricating bearings save time and money on preventative maintenance, and require no hazardous waste from the lubricant, disposal, or cleanup to handle.
In addition, the inlaid structure will reduce the strength of the bearing, resulting in low bearing capacity. Many scholars have studied the self-lubricating methods of sliding bearings such as electroplating, magnetron sputtering, inlaying solid lubricants, and adhesive self-lubricating liner. However, these traditional sliding bearing self-lubricating methods have some defects. One of the current advanced treatment technologies for self-lubricating sliding bearings is liquid coating technology, but the theoretical calculation of bearing spraying is litter. The phenomenon of bearing sag and leveling has not been studied deeply. The optimum thickness of coating, the best surface roughness of the substrate, and coating the optimum curing temperature and optimum cooling temperature of the layer also lack of relevant details and theoretical analysis. The studies of sliding bearings with wide temperature range self-lubricating coating materials under different temperature conditions are lacking. Tenmat manufactures self lubricating materials such as FEROGLIDE and FEROFORM. FEROGLIDE is a self lubricating bearing material that can endure high load and high temperature applications. It is best suited for conditions with low speed and high load.
