What kind of lubrication is used for sliding bearings?

Today, I will introduce what kind of lubrication is used for sliding bearings. Let's take a look at it together.

　　 Lubrication cycle of grease for sliding bearing:

　　 Unintentional accidental work, unimportant parts: shaft speed <200r/min, lubrication cycle once every 5 days; shaft speed >200r/min, lubrication cycle once every 3 days.

　　 Interruption of work: shaft speed <200r/min, lubrication cycle once every 2 days; shaft speed> 200r/min, lubrication cycle once a day.

Continuous work, working temperature is less than 40℃: shaft speed <200r/min, lubrication cycle once a day; shaft speed> 200r/min, lubrication cycle once per shift.

　　 Continuous work, operating temperature 40-100 ℃: shaft speed <200r/min, lubrication cycle once per shift; shaft speed> 200r/min, lubrication cycle twice per shift.

　　 Sliding bearings can also be lubricated with grease. The following points should be considered when choosing grease:

　　1) The selector has a grease with good adhesion.

　　2) The dropping point of the selected grease is generally higher than the working temperature by 20-30℃. In the case of continuous operation at high temperature, be careful not to exceed the permitted use temperature range of the grease.

　　3) When the bearing load is large and the speed is low, the grease with small penetration should be selected, otherwise, the grease with large penetration should be selected. For high-speed bearings, use grease with a smaller cone penetration and good mechanical stability. Special attention should be paid to the lower viscosity of the base oil of the grease.

　　4) When the sliding bearing is working in a water-drenched or humid environment, choose calcium-based, aluminum-based or lithium-based grease with good water resistance.
