The worm gear screw jack may experience vibrations during operation, generally including the following situations:

Screw jack lead is uneven

2. The screw jack worm gear head is unevenly distributed.

3. Purchased substandard plain bearing and tapered bearing products in the market, which did not meet quality standards.

4. The upper and lower protective sleeves of the ball screw are too tight, causing a vibration.

When the screw's load-bearing capacity is less than the actual load value, the screw will bend under the weight of the load, resulting in a vibration.
