slewing bearing

Large thrust ball bearings are specially designed to withstand thrust loads and are particularly suitable for mechanical equipment with low rotational speeds but large axial loads. Characteristics of large thrust ball bearings: 1.Using ultra-clean steel that can prolong the service life of large thrust ball bearings. 2. When selecting the type of large thrust ball bearing, in order to allow installation error, the spherical self-aligning spherical seat cushion type or the spherical seat ring type can be selected. 3. High lubrication technology, NSK's lubricant technology can prolong the life of grease and improve the performance of large thrust ball bearings. 4. The steel ball is of high quality, which can make the large thrust ball bearing rotate quietly and smoothly.

We provide customizable special-shaped slewing bearings, which are tailored to meet the specific needs of different mechanical equipment. Our special-shaped slewing bearings have the characteristics of high precision, high load capacity and low friction coefficient, ensuring the stable operation of the equipment in complex environments.

Ultra-thin black slewing bearing is a high-quality product that combines lightweight, high strength and anti-rust properties. It is manufactured using advanced precision processing technology to ensure ultra-high precision and stability of the product. The surface has been specially blackened, which not only increases the wear resistance, but also makes the product have good anti-rust effect.

In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings.

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.
