Under normal circumstances, double row deep groove ball bearing temperature should be around 30 ℃, the maximum temperature not exceeding 70 degrees Celsius, otherwise, because of bearing temperature caused deformation, in severe cases cause direct damage jaw crusher and more worse, directly cause the machine to explode. Therefore, be vigilant jaw crusher bearing temperature, especially in the summer season, more urgent.

One, bearing wear or damage cage. Second, bear in the hub axial movement occurs. Third, bearing off the oil or oil injected too much. Fourth, the crusher fly counterweight sheave position deviation, rack beating. Five hole clogged oil plus not enter. Six non-bearing heat up, but moving the jaw glands and cover friction heat or rack bearing double fitted lid rotates together with the spindle friction heat.

1. Keep clean and lubricated bearings

Former double row deep groove ball bearings should be checked before cleaning the bearing surface, and then carefully check the bearing seal and the surrounding parts, if the poor have shown symptoms, be sure to replace the lost, poor seal can cause damage, bearing cloud caused by abnormal equipment downtime.

2. Note the cover exposed bearings

Do not let the double row deep groove ball bearings are exposed to environmental contaminants or moisture check bearings. If the work is interrupted, should be oiled paper covered plastic sheet or similar material has been machine. If cleaning without masking the bearing under check is performed without disassembly possible circumstances, to coat with a brush to coat with oil solvent cleaning, then a lint-free cloth or compressed air (be careful not to let start rotating bearing assembly).
