How often do you add grease to the slewing ring?

The lubrication of the slewing ring generally uses grease, lithium-based grease is very commonly used. The most commonly used is No. 2 lithium based grease. According to the different working conditions of the slewing ring, such as temperature, speed, load, etc, also choose special greases, such as low temperature grease, high temperature grease, food grade grease,etc. The main function of grease is to form an oil film on the surface of the slewing ring and teeth, reducing friction coefficient, reducing friction, preventing wear of the slewing ring, at the same time preventing the raceway and teeth from rusting and it also has a certain dust-proof effect. The maintenance of the slewing ring bearing is very important. The installation and use should be in accordance with the installation manual. Need special attention, the slewing ring can not lack grease.

The slewing ring raceway has been filled with grease before leaving the factory, but the grease should still be filled after the first 50-100 hours of operation. After running for about 400 hours, check and add an appropriate amount of grease to ensure that the slewing bearing is in a good lubrication state. Under special working environment, such as high humidity, dust and continuous work, the lubrication period should be shortened and maintenance records should be made. 2# lithium-based grease is commonly used, but suitable grease should be selected according to the actual use environment.

The geared slewing ring needs to clean the oil on the gear surface and replace the grease regularly to prevent hard foreign matter such as sand and stone from entering the gear meshing area to damage the slewing ring to ensure that the gears are fully lubricated. Regularly check whether the seal of the slewing bearing is complete. If the seal is found to be off, it should be restored in time. If it is damaged, it should be replaced in time to prevent foreign matter or rain from entering grease and causing damage to the slewing ring.

Running under the condition of lack of lubrication is one of the most common causes of damage to the slewing ring. Whether it is grease failure, loss or contamination, if it is not replenished or replaced in time, it will cause the slewing ring to run without lubrication, which will cause serious damage to the raceway and gears of the slewing ring. If the slewing ring is not corrected in time, it will cause the slewing bearing to be scrapped, so when you use the slewing ring, it’s necessary to maintain it regularly and make records. Standard operation can make the slewing ring run stably and have a longer service life.
