CuW alloys are used where the combination of high heat resistance, high electrical and thermal conductivity, and low thermal expansion are needed. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks. As contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes for electrical discharge machining and electrochemical machining.
Copper–tungsten (tungsten–copper, CuW, or WCu) alloy is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy.

This type of bearing is equipped with a circular table-shaped roller; the roller is guided by the large rib of the inner ring. The poles of the conical surfaces of the inner ring raceway surface, the outer ring raceway surface and the roller tumbling surface are intersected on the bearing middle line. A little above. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Single row bearings can accept radial loads and one-way axial loads; double row bearings can accept radial loads and bidirectional axial loads.
Applicable to accept heavy load and impact load; according to the touch chest (α) is different; divided into small cone angle, middle cone angle and large cone angle three types; the larger the touch angle, the greater the axial load can be. It can be separated from the inner components (inner ring and roller and cage assembly); it is easy to assemble and disassemble; the bearing with the rear code "J" or "JR" has world interchangeability. This type of bearing also uses the British series.
The first applicable cage: steel stamping cage, synthetic resin forming cage, pin cage.
The primary use: car: front wheel, rear wheel, transmission, differential pinion shaft. Machine tool spindle, construction machinery, large agricultural machinery, railway vehicle gear reduction equipment, rolling mill roll neck and deceleration equipment.
Recommend to friends comments close window Bearing related knowledge The reason for the failure of the FAG bearing and the tumbling sound of the bearing in the field of use of the sounder: the smooth method of the rolling mill bearing handles the pump bearing and the seal is not resistant to wear and high temperature. The rolling bearing is diagnosed by the oscillation analysis method.
