What should we know before choosing turntable bearings?

The turntable bearing is widely used. Construction machinery is the first and most widely used place of turntable bearing, such as earth moving machinery, excavator, disintegrator, stacker reclaimer, grader, roller, dynamic compactor, rock drilling machinery, roadheader, etc. For more information, please read the following words.

How to properly maintain the turntable bearing?

However, if the turntable bearing is worn by the ball or the track, simply replacing the spare parts will not solve its use problem. Because the wear of the balls will inevitably increase the gap, the track will be damaged in the long run, and the track has a quenched thickness of about 3-5mm and a hardness of HRc55-62. If the hardened layer is damaged, it will soon become unusable after reinstallation.

Therefore, if the internal damage of the turntable bearing needs to be re-turned and re-quenched with steel balls, this is the best solution. Professional processing equipment is required. If it is confirmed that the track or the steel balls are damaged, it is recommended to consult professional turntable bearing manufacturers and supplier.

How to grade turntable bearing?

After the water spray test of the turntable bearing is done, wipe the slewing drive dry, remove the seal of the slewing drive housing and the seal of the turntable bearing, and check whether the tooth meshing part and the turntable bearing channel have water. Level 5 waterproof level, if water enters, it means that it has not been reached and needs to be improved.

The turntable bearing is used outdoors all day long, and generally it can reach the protection level of IP54, that is, it is dustproof and prevents the intrusion of water splashing from all directions. In order to improve the reliability of the slewing drive and minimize the maintenance frequency, we pursue longer use. Life, through reasonable design and precise coordination, the protection level of the rotary drive of the transmission has reached IP65, which will bring you a different experience.

What are the industrial applications of turntable bearings?

1. Special vehicles: bridge inspection vehicles, fire trucks, window cleaning machines, flat beam transport vehicles, aerial work vehicles, self-propelled aerial work platforms;

2. Light industrial machinery: beverage machinery, blow molding machine, packaging machinery, filling machine, rotary bottle unscrambler, injection molding machine;

3. Marine cranes: floating cranes. In addition to various construction machinery, the application range of turntable bearings has gradually expanded, and equipment platforms such as port equipment, metallurgical equipment, drilling platforms, etc. have begun to use turntable bearings instead of original bearings on a large scale.

4. Port equipment: port cranes, reach stackers;

5. New energy equipment: wind power generation equipment, solar power generation equipment;

6. Metallurgical equipment: metallurgical crane, ladle turntable, steel grabber, mud gun, oxygen blowing device, etc.
