swing bearing

1.The three row roller type rotary bearing has three seat rings, with the upper, lower, and radial raceways separated, and the load of each row of rollers can be accurately determined 2.Capable of withstanding various loads simultaneously, with large axial and radial dimensions and a sturdy structure

The slewing bearing of the shield machine has become an indispensable key component of the shield machine due to its strong bearing capacity, compact and reliable structure, convenient and quick maintenance, various structural forms, suitability for harsh environments, accurate selection calculation, high safety and wide application fields. We can design and produce according to customer requirements.

Slewing ring bearing is widely used in construction equipment like excavators. It is wear parts. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. If you need replacements of the steel balls, rollers or spacers, it is also available. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. If you have old slewing bearing in hand, we can instruct you to measure the detailed size to make a professional drawing and then manufacture it for you.

Large toothless slewing bearing is a large bearing that can withstand comprehensive loads. It has the characteristics of simple structure, strong load-bearing capacity, and smooth operation. We have a professional technical sales team to guarantee both quality and service. We can design and produce according to customer requirements. , repair, replacement and other services.

A crane refers to a multi action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. Also known as bridge crane, high-altitude crane, or crane. The slewing bearings used in cranes are mainly heavy-duty slewing bearings, which need to withstand large axial forces and overturning moments. The main function is to support the upper mechanism and control its rotation. The electric motor or reducer drives the small gear to rotate, and the small gear drives the slewing support to rotate, causing the upper mechanism connected to it to rotate accordingly.
