Jintai composite bearings are mainly the following materials:
Model: CHB-1
Modified PTFE (PTFE) and lead (Pb) of the sliding bearing mixture 0.01 ~ 0.03mm, a wear-resistant materials, the operation process can form a transfer film to protect the grinding shaft.
Copper powder layer 0.2 ~ 0.3mm PTFE / Pb to improve the bonding strength with steel, with good load capacity and wear resistance. At the same time copper is a composite bearing a good thermal conductivity material, can quickly transfer the heat generated during the operation of the bearing.
Low carbon steel 0.7 ~ 2.3, to improve the bearing capacity and thermal transfer effect.
Copper / tin plating, copper coating 0.008mm, tin plating 0.005mm, so that the bearing has a good corrosion resistance.
Application features: suitable for oil-free work. Static friction coefficient close to, to prevent the "crawling" phenomenon. Wide operating temperature range, can work in the -195 ° C ~ + 270 ° C temperature range. Wear resistance, friction coefficient is small, long service life. Good corrosion resistance, can be in a variety of corrosive media (including liquid and gas) work. High mechanical strength, can withstand greater stability and dynamic load. Can reduce the vibration of the machine, reduce noise, improve the working environment.
Model: CHB-2
1. Modified POM (POM) and lead mixture 0.3 ~ 0.5mm, with high wear resistance, even in the case of an instant lack of oil also has a low coefficient of friction. Bearing surface with a regular arrangement of the spiral angle with the oil pit, assembly, must be coated with grease.
2. Copper powder layer 0.2 ~ 0.3mm, has a good carrying capacity and wear resistance, good thermal conductivity can be transferred in time to run the heat generated during the operation of the bearing. The composite material can penetrate into the gap of the copper powder ball to improve the bonding strength.
3. Low carbon steel 0.4 ~ 2.2mm, to improve the bearing capacity and heat transfer effect.
4. Copper / tin plating layer, copper coating 0.005mm, tin plating 0.002mm, tin layer has rust-proof function.
Application Features: It is suitable for room temperature conditions, low-speed in the place, to replace the traditional copper sets, both to reduce costs and extend the service life. In special cases, the use of rolling mill, but also save the fuel frequency, simplify the replacement process. The product has been widely used in automotive chassis, forging machine tools, metallurgical mining machinery, engineering machinery, hydropower, rolling industry and other fields.
Model: CHB-800
CHB-800 bimetallic bushing with carbon steel as the base, the inner surface of the sintered hemispherical bronze layer; for high load low speed under the swing movement, rotary motion, with a low coefficient of friction, wear resistance, long life, Performance and other characteristics of good; copper alloy layer surface can be processed according to the needs of various types of oil tank, oil storage pit, etc., to be suitable for refueling or difficult to refuel the occasion. Products are widely used in engineering machinery with wheel hub, with wheel sleeve, tension wheel sleeve, automotive balance shaft bushing, steel Shaw bushing, steering knuckle Shaw Shaft, connecting rod sleeve, the valve rocker Bushings, camshaft bushings, differential bushings, thrust washers, plunger pump side panels, gear pump side panels and so on.
