1: Because the concentricity between the hollow shaft of the rotary joint and the rotating body used is not equivalent.
2: The installation machine has low precision and high vibration.
3: Slurry, dirt and other foreign objects enter the contact surface of the friction pair.
4: Use pressure, temperature, speed, etc. beyond the range of optional rotary joints.
5: Failure to add lubricating grease according to the prescribed time, failure to change the lubricating grease during high-temperature use of the rotary joint, abnormal or damaged sound of the ball bearings.
6: The friction surface of the sealing friction pair of the rotary joint is deformed, and the wear of the compensating ring is relatively large.
7: The sealing ring of the rotary joint is deformed, aged, cracked, and stuck.
8: The rupture and damage of corrugated pipes.
