China's Shandong bearing industry in-depth understanding

1) the surface of the raceway and roller surface is full of dents, keep on particulate matter and the raceway surface wear, grease (agent). Usually this kind of circumstance is the result of impurity in the installation process.When installation should keep clean, use the new grease, check whether the seal is in good condition at the same time.

Bearing ring raceway is bearing surface of workpiece, its quality is good or bad will directly affect the bearing performance and service life. In use process, we will often found some common quality problems on the surface of bearing ring, this quality problem is how to produce? Small make up many years of experience, to tell you bearing ring surface of the common quality problems and the cause.

"The fixed form of bearing which is the movement of the rolling bearing different ways, specific fixed form has the following several aspects.

Nylon cage is more of a bearing, nylon cage is mainly to prevent corrosion in special industrial varieties used greatly, therefore, nylon retainers are special, mainly adopts imported special material injection molding, and common material components are: glass fiber reinforced nylon and adding anti-aging agent, it has very good strength and elasticity , chemical resistance, anti-aging and good dimension stability characteristics.

Good adaptability, high low temperature performance, can be in indoor and outdoor, the north and the south.

Bearing as the main component of mechanical equipment, its types and with the development of the materials is different also, small make up explain common material use of deep groove bearings, deep groove bearings are the most common type of ball bearing, the basic model of deep groove ball bearing consists of inner ring and outer ring, ball and cage, lubricants, mainly depending on the use place we can be roughly divided into four kinds of materials .

Bearing ring raceway is bearing surface of workpiece, its quality is good or bad will directly affect the bearing performance and service life. In use process, we will often found some common quality problems on the surface of bearing ring, this quality problem is how to produce? Small make up for many years,Experience, to tell you bearing ring surface of common quality problems and the cause.

General with important cylindrical surface as a rough reference positioning, machining center hole, take the positioning precision of shaft center hole at the ends of the benchmark. As far as possible be unified benchmark, datum coincidence, as benchmark, and implement multiple surface processed once installed. Center hole is workpiece machining unified benchmark locating datum and inspection, its quality is very important, its preparation is relatively complex, often with supporting shaft neck positioning, car (drill) center cone hole; Again with central hole location, outside circle; Outside the circle positioning, coarse grinding taper hole; With central hole location, fine grinding cylindrical; Finally, supporting shaft neck cylindrical positioning, fine grinding (blow grind or grinding) cone hole, make the precision of the taper hole of the requirements.
