Ray Minder | Some tips for greasing the SJC series jaw breaker

April 13, 2023

Equipment lubrication is an important part of daily maintenance.。Lubricate the equipment on a daily basis，Yes, reduce failures，And that wear of the machine part is reduced,Extending the service life of equipment plays a vital role.。So what is the right way to use grease?？

The position should be correct

First，We need to find the right lubrication point.

SJCThe jaw Crusher has lubrication points on each of the four bearings

The amount should be just right.

Too much or too little grease for maintenance equipment，None of them！！

Too littleGrease，Increases dry friction due to insufficient lubricationToo muchGrease，The heat generated by the operation of the bearing is wrapped by the grease and cannot be dissipated，Resulting in an increase in temperature.！

Lubricating grease consumption for different types of jaw Crusher

*Notice：The proper amount of grease should occupy 30% of the total free space inside the bearing%～50%

The timing is right，Oil products are not mixed

Before lubricating the bearings，Thoroughly clean the area around each grease joint after closing the jaw Crusher，If the bearing is still warm, please add grease immediately. Different brands of grease should not be mixed.

There are several grease recommendations as follow：

A #2General Purpose Lithium Grease

Operating temperature alert:The normal operating temperature of the bearing is 40ºC-70ºCIf the bearing temperature exceeds 75ºCOr the temperature rise is higher than 35ºC，The machine must be shut down and the cause found If the temperature of one of the bearings is 10% higher than the other three bearingsºCTo 15ºC，The cause must be found out as soon as possible.
