What series of turntable bearings are common in the market?

Cross roller turntable bearing

The cross roller turntable bearing is similar to the single volleyball turntable bearing. There is only one row of rolling elements. The rolling elements are cylindrical rollers. The axes of the adjacent rollers are arranged in a 90 °cross. The inner and outer rings have two raceways respectively, and the raceway section is linear. Half of the rollers bear the downward axial force and half bear the upward axial force.

Double row reducing ball turntable bearing

The double volleyball turntable bearing has three seat rings. The steel balls and isolation blocks can be directly discharged into the upper and lower raceways. According to the stress condition, the upper and lower rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient. The bearing angle of the upper and lower arc raceways is 90 °, which can bear great axial force and overturning moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The axial and radial dimensions of double volleyball turntable bearing are relatively large and the structure is fastened. It is especially suitable for tower cranes, truck cranes and other loading and unloading machinery requiring medium or above diameter.

What should I pay attention to when repairing the turntable bearing by myself?

Generally, the quality guarantee time of the turntable bearing is calculated from the date of delivery, and the quality assurance of the turntable bearing ends after 12 months. After some users purchase the turntable bearing, due to equipment or other reasons, the turntable bearing needs to be placed for several months before being activated. Once the turntable bearing fails at the time of the warranty, equipment maintenance costs will be incurred. For example, can the turntable bearing be repaired by itself? What problems do you need to pay attention to when repairing yourself?

In fact, the structure of the turntable bearing is very simple. The main thing is to put the balls in the two circles. It is not impossible to repair the turntable bearing by yourself. If it is a simple damage, such as the nylon spacer inside is broken, take it apart and reinstall it.

What should be paid attention to when transporting turntable bearing?

Packaging, transportation and storage of turntable bearing: Before packaging the turntable bearing, the inner and outer raceways need to be coated with anti-rust and lubricating grease, then wrapped with plastic film, compounded with kraft paper, and then wrapped with industrial wrapping tape for inner packaging. The outer packing adopts special wooden box or iron box.

During transportation, the bearing should be placed horizontally on the vehicle, and there should be measures to prevent sliding and vibration, and auxiliary support should be added if necessary.

Due to different fields and different types of turntable bearing, they are widely used in many industries. To meet these growing demands,LYXQL Slewing Bearing Co., Ltd. Founded has committed to providing the increasing of turntable bearings, and make them more effective, reliable, and consistent.
