Jaw crusher connecting rod bearings, eccentric shaft bearings, thrust plate elbow head lubricating oil. The 70 # mechanical oil is more suitable in summer. Mechanical oil No. 40 can be used in winter. If the crusher works continuously and has oil in winter, and the ambient temperature is not too high in summer, 50 # mechanical oil can be used to lubricate the crusher.
In addition, the jaw crusher lubrication should be noted:
1,Always pay attention to and do the lubrication work of friction surface in time to ensure the normal operation of the machine and prolong the service life of the equipment.
2,The grease used is general purpose lithium grease or compound calcium grease, or grease required by manufacturer.
3, The grease added into the bearing seat is about 50% of its space volume, every nine classes are added and replaced once every 3-6 months. Apply clean gasoline or kerosene to clean the raceways of ball bearings when changing oil.
4, Between the elbow plate and the elbow seat should inject the proper amount of grease.
