工业润滑油主要有液压油、齿轮油、汽轮机油、压缩机油、冷冻机油、变压器油、真空泵油、轴承油、金属加工油（液）、防锈油脂、气缸油、热处理油和导热油等。此外，还有润滑油为基础油，并加有稠化剂的润滑脂。
Industrial lubricants mainly include hydraulic oil, gear oil, turbine oil, compressor oil, refrigeration oil, transformer oil, vacuum pump oil, bearing oil, metalworking oil (liquid), antirust grease, cylinder oil, heat treatment oil and heat transfer oil. In addition, there are lubricating oil base oil, and add thickener grease.
工业润滑油的用户是各行各业的企业，一般使用的品种多、用量大，不仅取决于产品的价格，而且取决于产品的质量和技术特性，同时更取决于技术服务的好坏。
The users of industrial lubricants are enterprises from all walks of life. Generally, they use many kinds of lubricants with large consumption, which not only depends on the price of products, but also depends on the quality and technical characteristics of products, but also depends on the quality of technical services.

工业润滑油的基本性能和主要选用原则是粘度。
Viscosity is the basic performance and main selection principle of industrial lubricating oil.
1.在中转速、中载荷和温度不太高的工况下，选用中粘度润滑油；
1. Medium viscosity lubricating oil is selected under the working conditions of medium speed, medium load and low temperature;
2.在高载荷、低转速和温度较高的工况下，选用高粘度润滑油或添加极压抗磨剂的润滑油；
2. Under the working conditions of high load, low speed and high temperature, choose high viscosity lubricating oil or lubricating oil with extreme pressure and antiwear agent;
3.在低载荷、高转速和低温的工况下，选用低粘度润滑油；
3. Choose low viscosity lubricating oil under low load, high speed and low temperature;
4.在宽高低温范围、轻载荷和高转速，以及有其它特殊要求的工况下，选用合成润滑油。
4. Under the conditions of wide range of high and low temperature, light load, high speed and other special requirements, synthetic lubricating oil should be selected.
