How to run a high-speed rotary joint normally

If the bearing cannot withstand high-speed rotation, no matter how good the accessories are, the bearing should have good heat dissipation and load-carrying capacity. The sealing properties of the bearing material and bearing sleeve also affect the service life of the bearing. Poor heat dissipation or lack of oil in the bearing can cause clogging. Because the butter is not resistant to high temperature, the heat dissipation is not good, and the bearing temperature is too high, which causes the butter to melt. Don't underestimate this problem. It is recommended to separate the bearings, put more high temperature resistant butter in the middle, and drill more heat dissipation holes to ensure that the bearings are not short of oil and run at room temperature.
　　Sometimes, in order to reduce costs, when choosing a seal, only the end face of the hollow shaft is ground flat, which will cause high temperature due to friction with the graphite seal ring, and the end face of stainless steel will become soft, causing wear and tear, resulting in seal damage, or even scrapped high-speed rotary joints; Silicon carbide should be selected as the sealing ring, which can avoid the abrasion of the end face of the hollow shaft, and avoid the damage to the shaft head due to high temperature, and prevent leakage during high-speed rotation.
　　Nowadays, new types of rotary joints are emerging in endlessly, which also requires our rotary joint production and R&D companies to provide better quality and safer high-speed rotary joints.
