What Is Slewing Bearing Without Gear

With the rapid development of society, the rapid development of machinery has brought great convenience to human life. More and more mechanical products are being put into people's lives, and with the machinery there must be bearings called "mechanical joints." A slewing bearing without gear is one of the bearings, which is classified into one class because of its distinctive characteristics. This article will detail the information on slewing ring without gear to help readers understand it.

This article contains the following:

• Definition of slewing bearing without gear 

• Application of the slewing bearing

• maintenance of the slewing ring bearing

1、Definition of the slewing bearing

Slewing bearing without gear are made of chrome, carbon and stainless steel. It has an inner ring, an outer ring and a steel ball. Slewing ring without gear are used in a variety of rotating machines with or without eccentric loads. Such as reducers, pumps, cranes and jacks. We offer different types of the slewing bearing according to your requirements. Different types of the slewing bearing have different load carrying capacities. Among all these types, the gearless three-row roller slewing bearing has maximum load and is particularly suitable for heavy machinery such as wheeled excavators, wheeled cranes, marine cranes, ladle turrets and heavy duty mobile cranes.

2、Application of the slewing bearing

1) Rotary conveyor

2) Welding manipulator

3) Light car

4) Excavator and other construction machinery

3、Maintenance of the slewing ring bearing

Under normal working conditions, after the slewing bearing is operated for 100 hours for the first time, the inside of the raceway should be refilled with new grease once (the tower crane that has been shut down for a long time must also pay attention to the new new grease once). Check every 400 hours after the operation and apply proper amount of grease to keep the slewing bearing in good lubrication. In special working environments, such as tropical, humid, dusty, temperature differential, and continuous operation, the lubrication cycle should be shortened. Maintenance records should be made after each lubrication.

The slewing bearing tooth surface should be cleaned and replaced once every 10 working days to prevent the hard objects such as iron filings, sand and graves from approaching or entering the tooth meshing area.

After the slewing bearing is operated for the first time for 100 hours, the pre-tightening force of the bolt should be checked. After every 500 hours of operation, the pre-tightening force must be maintained.

Always check the integrity of the seals. If the seals are found to be damaged, they should be replaced in time. If the seals fall off, they should be reset in time to prevent the rain from entering the raceway and causing the grease to fail.

Greases of different manufacturers or different types of greases cannot be mixed to avoid premature failure of grease.

To add grease to the raceway: first remove the four M10x1 oil cups on the inner ring of the slewing ring and the grease nipple on the oil gun. Fill the oil gun filled with grease through the oil pipe directly to the inner ring of the slewing ring. The M10x1 oil injection hole is screwed, and while the slewing bearing is slowly running, the grease is injected into the slewing bearing raceway through the oil gun to ensure uniform filling of the grease. During normal maintenance, observe the upper surface of the slewing bearing and fill it until the grease oozes along the upper sealing belt. When using for the first time or after long-term deactivation, you need to add 1.5 to 2.0 liters according to the above method to complete the original grease. Extrusion replacement.

The characteristics of the slewing bearing without gear are as described in this article. It has the characteristics of most bearings and also has its own characteristics. The length of the ruler is short, and the slewing ring without gear has the corresponding advantages and disadvantages of different structures. Therefore, when selecting, it is necessary to find a suitable bearing according to the demand.
