The bearing is a main oil site of the generator, long-term running temperature is reachable over 80 ℃, summer is penetrated in the wilderness area directly by the sun, the temperature will be higher. So, requiring the bearing grease of generator keeps the good lubrication under the high temperature without running off, and the generator capacity is relatively large, require the grease to have good resisting and rubing and pressing characteristic, anti-oxidant characteristic and characteristic of antirusting very much. Mainly recommend the load which uses 2 # - consistency No. 3 to ...

Choice of lubricant A, lipoprotein lubricate and the comparison of the oil lubrication The bearing lubricated method is roughly divided into lipoprotein lubricating and two kinds of oil lubrication. In order to give full play to the function of the bearing, the more important thing is according to the service conditions and use the purpose, adopt the lubricated method. B, lipoprotein are lubricated The grease is lubricant composed of base oil, thickening agent and additive. While choosing the grease, should choose to be very suitable for the grease of the bearing service conditions. Even ...

The unit of the hub bearing must meet increasingly severe and lightweight, energy-conservation and modularization requirement. In addition, it is safe and reliable when in order to guarantee to brake, anti-lock brake system ABS Also popularize day by day. So the demand for the built-in type hub bearing unit of the sensor of the market is greater and greater. NSK relies on first-class original new and high technology and various rigorous platforms of bearing producer to drive the testing data, have succeeded in developing and having high-quality small-scale, lightweight, built-in type hub ...

The markets of different mechanism, instrument,etc. which use the antifriction bearing require the characteristic to be strict day by day, the required condition, characteristic as to bearing are diversified day by day too. In order to choose the most appropriate bearing from numerous structure, size, need studying from various angles. While choosing the bearing, generally, consider difficulty or ease degree, bearing acceptable space, marketability of the size and bearing,etc. that the bearing as line shafting is arranged, installed, dismantled, roughly determine the bearing structure. ...

The washing of the bearing: While dismantling the lower bearing to overhaul, record the appearance of the bearing at first, confirm the remaining quantity of lubricant, after the lubricant used for taking a sample to check, wash the bearing. As cleaning agent, use the petrol, kerosene ordinarily. The washing of the bearing dismantled, divide thickly and wash and thin washing, put in the container respectively, put the metallic network and lag behind first, make the bearing not contact the dirt of the container directly. Thick while washing, if make the bearing take the dirt to rotate, will ...

First, the installation of the bearing: The installation of the bearing must go on under the dry, clean environmental condition. Should check matching the end, cannelure on the surface, shoulder and connecting externally and processing quality of axle and outer cover carefully before installing. All cooperation connecting surface must be washed and eliminated and debured carefully, the crude surface of the casting must clean-out the molding sand. Bearing should wash before the installation, use after being dry, and guaranteed to lubricate well, the bearing generally adopts the lipoprotein ...

In order to maintain the original characteristic of the bearing with the good state as for a long time as possible, must maintain, overhaul, so that accident proof on right, guarantee reliability that turn round, improve productive, economy. Maintain the operation or work standard of the condition of operating of preferably corresponding machinery, go on regularly. The content includes the inspection that monitors the running condition, supplements or changes lubricant, dismantles regularly. As overhauling the item in operation, there are rotatory sound, the states of the vibration, ...

Characteristic of the products The electrical insulation bearing that ZWZ produces adopts the special spraying craft, in the high-quality membrana tectoria of outer surface plating of the bearing, membrana tectoria and matrix binding force are strong, good insulating property, can avoid the induction current is applied the electrolytic corrosion of the bearing, the damage of preventing the electric current from causing to the grease, rolling element, ball track, raise the life time of the bearing. Suitable for electrical machinery, generator, especially the frequency conversion electrical ...
