High-speed rotating bearings need to be maintained with oil mist lubrication

It is understood that the amount of grease added and the time interval for the next lubrication need to be taken care of. Installing an automatic tanker and controlling the regular addition of a small amount of grease will facilitate maintenance and at the same time improve lubrication.

Sand producers believe that thin oil lubrication is good, because when the temperature or speed can not be used when the grease can not be used, it should be lubricated with lubricants. Oil bath lubrication at this time is a simple method. Sometimes circulating oils (and possibly cooling systems) are used, especially for large vibratory mills to control the bearing temperature. Oil mist lubrication is mainly used for small bearings that rotate at high speed, and positive pressure is very effective in preventing the entry of contaminants.

It is recommended to use an antioxidant mineral oil which has a viscosity of 40 to 80 mm/s (ie 40 to 80 cSt) at 40°C, and this oil must contain EP, preservatives and anti-foaming agents. The height of the oil level should be flush with the centerline of the lower roller. Self-aligning roller bearings recommended amount of fuel. The level of oil and the condition of the oil should be checked regularly. Usually, after working for 6 months, you should change the oil.
