What are the lubricants for roller bearings

The lubricant inside the roller bearing can generally be divided into two types: oil and grease. Basically, most of the lubricants used in the production of roller skates are grease 

lubricants, and some products currently on the market use oil as a lubricant.

The selection of bearing lubricants mainly considers the use temperature, load, speed, and working environment, and distinguishes between rolling bearings or sliding bearings 

to choose grease or oil for lubrication. Most rolling bearings are lubricated with grease. Most sliding bearings are lubricated with oil. Generally speaking, low-speed bearings are 

suitable for grease lubrication, while high-speed bearings are suitable for oil lubrication.

1. Definition of equipment speed

List the criteria for defining high, medium, and low speeds during equipment operation, as well as the maximum operating speed limits for grease lubricated equipment. The 

speed limit of grease lubricated rolling bearings is 350000, the speed limit of lubricated sliding bearings is 5m/s, the speed limit of lubricated gears is 10m/s, and the speed limit 

of lubricated turbines is 5m/s. When the operating speed of the equipment exceeds the limit, grease lubrication should not be used.

2. Definition of Equipment Load

The definition of equipment load is listed, and extreme pressure grease lubrication should be selected for operating equipment with medium and high loads.
