In contrast, let's take a look at the benefits of lubricating grease commonly used in Yangzhou NSK bearings.
（1）扬州NSK轴承润滑油与润滑油相比，具有良好的附着性、不损失、不掉落、耐压性好、密封性好、耐腐蚀等优点。由于润滑脂不易泄漏，所以润滑脂几乎是永久性润滑，特别是对于立式或倾斜机床，使用油脂润滑来实现连续润滑效果。然而，其扬州NSK轴承主要缺点是，与油润滑耐磨性相比，功率损失较大。此外，它不能起到良好的摩擦和散热作用。影响油脂选择的主要因素有三个。
(1) Yangzhou NSK bearing lubricating oil compared with the lubricating oil, has good adhesion, no loss, no falling, good pressure resistance, good sealing, corrosion resistance and so on. Because the grease is not easy to leak, so the grease is almost permanent lubrication, especially for vertical or inclined machine tools, using grease lubrication to achieve continuous lubrication effect. However, the main disadvantage of the NSK bearing in Yangzhou is that the power loss is larger than that of oil lubrication and wear resistance. In addition, it can not play a good role in friction and heat dissipation. There are three main factors affecting the selection of oil and fat.
（2）扬州NSK轴承工作速度是润滑脂选择的重要因素。它可以由公式DN测量，其中D（mm）表示轴承内圈的直径，而n（r/min）表示速度。对于NSK轴承，润滑脂的DN值约为0.3×106。
(2) the working speed of NSK bearings in Yangzhou is an important factor in the selection of grease. It can be measured by formula DN, where D (mm) represents the diameter of the bearing inner ring, while n (r/min) indicates speed. For NSK bearings, the DN value of grease is about 0.3 * 106.
（3）扬州NSK轴承选用高粘度润滑脂和润滑脂，润滑脂过小，在接触面之间形成良好的润滑膜。随着轴承载荷的减小，润滑脂的粘度降低。
(3) Yangzhou NSK bearings choose high viscosity grease and grease, the grease is too small, in the contact between the formation of a good lubrication film. As the bearing load decreases, the viscosity of the grease decreases.
（4）润滑脂的选择受温度的影响。温度的变化会引起轴承粘度的变化，从而影响润滑性能。扬州NSK轴承润滑脂的粘度不应低于20平方毫米/秒。在选择润滑脂时，应注意润滑脂的滴点、渗透性和低温性能。
(4) the selection of grease is affected by temperature. The change of temperature will cause the change of bearing viscosity, thus affecting the lubrication performance. The viscosity of Yangzhou NSK bearing grease should not be less than 20 mm2 / sec. When choosing grease, attention should be paid to the dropping point, permeability and low temperature performance of the grease.
（5）这些是影响润滑脂选择的主要因素，但在许多实际条件的影响下，它们也根据润滑脂的不同性质，如润湿或润湿条件而选择。不溶性油应是首选。扬州NSK轴承水溶性润滑脂应用于干燥潮湿的环境中。
(5) these are the main factors affecting the selection of grease, but under the influence of many practical conditions, they are also chosen according to the different properties of the grease, such as wetting or wetting conditions. Insoluble oil should be the first choice. Yangzhou NSK bearing water-soluble grease should be used in dry and moist environment.
