Sliding bearing grease should be used when handling

1. When the bearing load is large and the speed is high, the grease with a large penetration degree should be selected. Otherwise, the penetration degree should be small. If it is a high-speed bearing, use a grease with a small penetration and good mechanical stability. Special attention is paid to the lower viscosity of the base oil of the grease.

2. The dropping point of the grease should generally be higher than the working temperature of 20-30 °C. In the case of continuous operation at high temperature, special care should be taken not to exceed the allowable operating temperature range of the grease.

3. If the sliding bearing is working in a water or wet environment, choose a calcium-based, aluminum-based or lithium-based grease with good water resistance.

4. Use grease with better adhesion.

Next, Xiaobian introduces the lubrication cycle for everyone. The cycle problem is also to attract everyone's attention. How often does it lubricate once? It is different according to different working conditions. The lubrication cycle of sliding bearing grease is as follows:

1. Continuous operation, working temperature 40-100°C, shaft speed <200r/min, lubrication cycle once per shift; shaft speed>200r/min, lubrication cycle twice per shift.

2, continuous operation, working temperature is less than 40 ° C: shaft speed <200r / min, lubrication cycle once a day; shaft speed > 200r / min, lubrication cycle once per shift.

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

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

The above is the introduction of the precautions for the use of sliding bearing grease. On the one hand, we understand the precautions when selecting the grease for the sliding bearing, and on the other hand, the cycle problem that should be paid attention to during the use of the grease. For these questions, if you still don't understand, you can also ask the professionals around you to avoid unnecessary troubles caused by your blind behavior.
