Lightweight Spherical Roller Bearing industrial robot includes Bearing, Roller Spherical Lightweight thin Lightweight Spherical Roller Bearing crossed cylindrical roller, harmonic reducer Lightweight Spherical Roller Bearing and Lightweight Spherical Roller Bearing joint, but the main is Lightweight Spherical Roller Bearing crossed roller. Welding robot joint in Lightweight Spherical Roller Bearing cross roller structure: Lightweight Spherical Roller Bearing in cylindrical roller cylindrical raceway vertical arrangement, a single Lightweight Spherical Roller Bearing can also bear radial force, two-way axial force and overturning moment of common load. Lightweight Spherical Roller Bearing has the advantages of large load capacity, good rigidity, high rotary accuracy, easy installation, saving space, reducing weight, reducing friction, and providing good rotary accuracy. It is possible to make the light and miniaturization of the main engine possible. So whether you will identify the robot Lightweight Spherical Roller Bearing quality is good or bad, the following we and technical personnel together to discuss how to choose a good Lightweight Spherical Roller Bearing.
1, first look at the use of Lightweight Spherical Roller Bearing steel material, Lightweight Spherical Roller Bearing products are produced by their own professional steel mills, hardness and precision are higher than the fake Lightweight Spherical Roller Bearing.
2, using high input marking equipment, in order to establish a corporate brand image, to prevent counterfeit products are Lightweight Spherical, Roller Bearing manufacturers have adopted the laser marking machine, hope to establish a corporate image, and the international community at the same time, with high input to control the products being counterfeited, however, because the use of computer controlled laser marking machine, labeling, font the size of the editor convenient, not only can effectively prevent counterfeiting, but to increase the difficulty of counterfeiters.
3, observation method. Lightweight Spherical Roller Bearing rolling observation with the naked eye, both inside and outside the raceway there should be no signs of peeling and serious wear, and there is a circular groove; all the rolling surface should be no spots, cracks and peeling; cage should not be loose, no damage, no wear, and the rolling body but the big gap.
4, handle method. The gap between the inner and outer race of the normal Lightweight Spherical Roller Bearing and the rolling body is between 0.005 and 0.010 millimeters. For a rolling Lightweight Spherical Roller Bearing that has been used for a period of time, no obvious open motion should be observed when the inner seat is pinched by hand for axial sway.
5, rotation method. The Lightweight Spherical Roller Bearing inner ring is clamped with one hand and the outer seat ring is rotated by the other hand. The Lightweight Spherical Roller Bearing should be flexible and should not be able to feel radial sway.
6, of course, depends on the price, if the price is much lower than normal, it may be false, it is not recommended to buy, after all, a penny of goods, after all, the cost is high, so the import is very expensive.
The above method is only a simple identification method, of course there are other ways such as can be judged from the color, precision, also can do from the brand choice, this is not one by one example, I hope these methods can help to you, our company is a professional production and sales of Lightweight Spherical Roller Bearing, product variety, quality assurance and welcome to our company to buy.
