Product Description

Bronze Plugged Bearings Special lubricant graphite for use in high temperatures between 250 and 500 ºC.

CDA95400 ASTM A505 BRONZE BEARINGS 

 
Bronze Plugged Bearings are customer-specified products. Its base is CuSn10P1 material which is lead-free and is widely used in powder metallurgy products. It has relatively low coefficient of friction but also relatively low load bearing capacity. After graphite impregnation, it can be used without oil lubrication.Compared with regular bronze bearings, Bronze Plugged Bearings has much better elasticity and wear-resistance properties, is mainly used in low load, high temperature, and moderate speed applications.

The sobf-sankyo maintenance-free plain bearings are made of very hard bronze (base material) and specially arranged solid grease (graphite).Set the graphite to match the direction of travel.The base material bears the load, and the solid grease ensures the lubrication of the bearing throughout its service life.The graphite composition must be able to lubricate the sliding surface of bronze.As the bearing rotates, the grease film diffuses to brown.This means that there is always a gap between the two sliding surfaces in order for the bronze and graphite to work effectively.Recommended maximum operating temperature: 300°C (bearing manufactured at 1000°C) greater clearance shall be provided to compensate for thermal expansion at operating temperatures above 100°C.Necessary maintenance usually involves checking consumption every six months to two years, depending on usage time and load.It is recommended that the parts be re-lubricated each time they are removed.Do not remove the existing solid grease layer.Continuous lubrication is not required, as the part does not require maintenance if all requirements for the use of bronze with solid grease are complied with.Machining: SANKYO bronze is easy to process.Basically, there is not much difference between our products and ordinary steel processing.No special tools are required, but remember to use sharp tools, preferably new ones.It is recommended to use the grease for HSS or carbide tools.As with ordinary steel, the distance of the machine is about 0.3 mm during rough milling.When milling/roughing, use low feed rate and low cutting depth.

Application characteristics


Jdb-1 is a universal basic product, regardless of high pressure, low pressure, high temperature, low temperature, oil lubrication, oil free lubrication or water lubrication.They all apply.The matrix of the product is high-strength brass, which is twice as hard as the general copper cover.Wear resistance increased more than twice.Therefore, the continuous casting machine, rolling mill, conveyor in the metallurgical industry can be used.Also used for plastic injection molding machine locking mechanism, extrusion mechanism.Automatic switch of high voltage, lifting support of construction machinery, and arc door support of water conservancy project.Pulley and drive wheel parts.There are also paper dryer, automobile mold, ship anchor sliding parts and so on.
JDB 1 2 is mainly suitable for low load, high temperature and medium speed applications, such as fireplace door hinges, oven raceway, light industrial machinery, machine tool industry, etc.
The internal material of jdb-3 is the same as that of jdb-2. In addition to the function of jdb-2, it also reflects the functions of saving cost, improving compressive strength and welding and installation of end face and matrix. It is suitable for non-oil lubricating parts in construction machinery, metallurgical machinery and conveying machinery.
 
Jdb-4 is a typical material - saving product where mechanical properties are not required.It can be used as a substitute material for jdb-2.Can greatly reduce the cost, to meet the use of requirements, such as: mold guide sleeve, injection molding machine mold frame.
 
Jdb-5 is an enhanced product.It has very high compressive performance, especially suitable for supporting parts of the crane, such as excavator support, winch support, crane support, etc.But because the matrix is steel.So should not be used in water or acid, alkali occasion.
