What are the precautions for bearing protection at the connection between the cam-opening connecting rod and the lifting arm?

Due to its special location, the bearing at the connection between the cam-opening connecting rod and the lifting arm is difficult to maintain routinely. Prolonged exposure to a humid environment can easily lead to moisture intrusion, causing bearing corrosion. Simultaneously, the internal grease will gradually evaporate, accelerating the wear and damage of the YS629 bearing and the short connecting rod. For the cam-opening device, it is recommended to evenly apply No. 3 lithium-based grease to the bearing and surrounding connecting rod before the equipment is put into use, and establish a regular maintenance system, checking and replenishing the grease at least every six months to effectively isolate moisture, reduce friction, and extend the service life of key components of the cam-opening device.
