Oilite Bronze Bushings Catalog
Oilite Bronze Bushings has a wide selection of standard metric sleeve bearings, flange bearings, thrust washers available. We can also make any custom metric bearing designed in our Bearing Calculator.
What Is Oilite Bronze Bushings?
SAE 841—also called Oilite bushing, this bushing starts as powdered metal and is then sintered and impregnated with roughly 19% SAE 30 oil. The oil reduces wear as well as provides lubricant.
Powdered metal bearings (SAE 841) are used in applications that call for completely wear-resistant components. Self-lubricating oilite bronze bushings are made by blending powders, shaping the mixture into the required sizes, and heating it in the oven to bond the particles. The next step in the process is to size the bronze bushing; this involves placing the material back into the dye and pressing it into the finished shape. The next step in the process is to oil-impregnated the metal bronze bushing for lubrication or corrosive resistance. This creates a fantastic cost-efficient bearing. Operation temperatures range from 10* F to 220*F. Shipped in a plastic bag to preserve the oil. We offer many sizes, in inch dimensions sleeved and sleeved with flanges. Metric bronze bushings are also available upon request.
Oilite Bushings Technology
Pulverizing is the process of making raw materials into powder. Commonly used pulverizing methods include the oxide reduction method and the mechanical method.
Mixing is the process of mixing various required powders in a certain proportion and homogenizing them to make green powder. There are three types of dry, semi-dry and wet, which are used for different requirements.
Forming is a process in which the mixed material is evenly mixed, loaded into a die and pressed into a parison with a certain shape, size and density. The molding method is basically divided into pressure molding and pressureless molding. The most widely used compression molding is compression molding.
Sintering is a critical step in powder metallurgy process. The formed compact is sintered to obtain the desired final physical and mechanical properties. Sintering is further divided into unit-system sintering and multi-system sintering. In addition to ordinary sintering, there are special sintering processes such as loose sintering, infusion method, and hot pressing method.
After sintering, various methods can be adopted according to different product requirements. Such as finishing, oil immersion, machining, heat treatment and electroplating. In addition, in recent years, some new processes such as rolling and forging have also been applied to the processing of powder metallurgy materials after sintering, and achieved ideal results.
Oilite Bronze Bushing – Precision Sintered Products
These simple bush-style bearings are cost-effective, noiseless in use,
These oilite bronze bushings have a wide range of uses, but they’re especially well suited for applications involving high or low temperatures, high or low speeds, a corrosive environment, or an application where low maintenance is important.
The greasing process implants the bushes with lubricant, with a temperature range between -20C and +90C. If you need bearings that will compensate for medium temperatures, or for a wide range of temperatures, talk to us – we can help suggest further options.
Application Of Oilite Bronze Bushing
Oilite bronze bushing have a wide range of applications, from common machinery manufacturing to precision instruments; from hardware tools to large machinery; from electronic industry to motor manufacturing; from civil industry to military industry; from general technology to cutting-edge high technology, all can see the figure of oilite bushing process.
Oilite Bronze bushing parts are widely used in automobiles
Aerospace industry oilite bushing
Oilite bushings materials used in the aerospace industry, a class of special functional materials, such as friction materials, wear reduction materials, sealing materials, filter materials, etc., mainly used in aircraft and engine auxiliary, instrumentation and on-board equipment. Another type of high-temperature and high-strength structural materials, mainly used in the aircraft engine main engine on the important structural parts.
Advantage | China Oilite Bushing Sintered
Oilite bronze bushing is a process technology that uses metal powders (or mixtures of metal powders and non-metal powders) as raw materials, which are shaped and sintered to manufacture metal materials, composite materials and various types of products.
Advantages of oilite bushing
1. The oilite bushing manufacturing process is less.
2. The utilization rate of material can be more than 95% when manufacturing gears by powder metallurgy.
3. The repeatability of oilite bronze bushing is very good. Because oilite bushings are pressed into shape with a mold, under normal conditions of use, a pair of molds can be pressed into tens of thousands to hundreds of thousands of bronze bushing.
4. Powder metallurgy method can be integrated manufacturing of several parts.
5. The material density of oilite bushing is controllable.
6. In oilite bushing production, the roughness of the working surface of the press die is very good to facilitate the release of the press billet from the press die after forming.
