Where is the national standard size of JDB self lubricating bearings?

JDB self-lubricating bearing is self-lubricating copper sleeve (graphite copper sleeve), the production of national standard: GB T23894-2009, you can in Jiashan Chenhan bearing ** in the national standard, which has many sizes and specifications of JDB bearing for your reference and selection. If you don't understand anything, please feel free to send me a private message.

Bimetallic bearing housing is one of the oil-free smooth bearing housings, which is based on high-quality low-carbon steel back, sintered lead-tin bronze alloy on the surface, and formed into a bimetallic strip integrating copper and steel by several times of low-temperature sintering and dense rolling.

The product has the advantages of high joint strength, large bearing capacity, good wear-resistant function, and national standard. It is especially suitable for medium-speed, medium-load and low-speed and high-load places. After special technology, all kinds of oil grooves, oil pockets and oil holes can be processed on the friction surface, so as to adapt to the application of different smooth requirements.

The products have been widely used in automobile starters, chassis, motorcycle clutches, gear pump wipes and lifting equipment.

Metal-based inlaid solid self-smoothing bearing housing (referred to as JDB) is a unique smooth bearing housing with both the characteristics of metal bearing housing and the characteristics of self-smoothing bearing housing. It has the characteristics of high bearing capacity, impact resistance, low temperature resistance, and strong self-smoothing, especially suitable for heavy load, low speed, reciprocating or swinging and other places that are difficult to smooth and constitute an oil film, and are not afraid of water erosion and erosion of other acids. The majority of players generally report that the inlaid self-lubricating bearing housing is not only fuel-efficient and energy-saving, but also has a longer mission life than ordinary plain bearing housings.

At present, the products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment consumption lines.

Self-lubricating bearings JDB and SF can also be called Rongchang graphite copper sleeves and Rongchang self-lubricating bearings.

Remegen self-lubricating bearing JDB is based on high-strength copper alloy (CUZN25Al5, CUZN24Al6Fe3Mn4 or C86300, C95400, C95500, C95800) as the basic material, Rongchang SF is composed of 4 layers of self-lubricating bearing;

1.The mixture of PTFE and fibers forms a good transfer film to protect the grinding shaft and provides the self-lubricating properties of the bearing.

2.The copper powder layer has good bearing capacity and wear resistance, and good thermal conductivity can transfer the heat generated during the operation of the bearing in time. The composite material can penetrate into the gaps of the copper powder balls, improving the bond strength.

3.Low-carbon steel, which provides very good load-bearing properties and heat transfer.

4.Copper and tin plating layer to make it have better corrosion resistance.
