Double Row Roller Bearing NN3032K/W33 Cylindrical Roller Bearings-manufacture,factory,supplier from China

According to whether the ring has a rib or not, NSK cylindrical roller bearings are divided into NU, NJ, NUP, N, NF and other single-row bearings, and NNU, NN double-row bearings. The bearing is a structure with separable inner ring and outer ring. Cylindrical roller bearings with inner or outer rings without rims, the inner and outer rings can be axially moved relative to each other, so they can be used as free-end bearings.

The different types of cylindrical roller bearings are designated based on their structural features and intended applications: N..EM: Cylindrical roller bearing with a standard inner ring without any ribs, suitable for radial loads. NU..EM: Bearing with aremovable inner ring and two integral flanges on the outer ring, designed for high radial loads and accommodates axialdisplacement. NJ..EM: Features a removable inner ring and one integral flange on the outer ring, primarily used for applicationswhere axial displacement is required.

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.

Slewing bearing has four series of toothless, external and internal toothed four-point contact ball bearings, double row angular contact ball bearings cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller composite bearings, of which four-point contact ball bearings have higher static load capacity, cross cylindrical roller has higher dynamic load capacity, The pre-interference of cross-tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy.

Single row tapered roller bearing is a common rolling bearing, which is composed of an inner ring, an outer ring, a roller and a cage. Its structure is similar to a conical shape, which is why it gets its name.The contact points on the inner and outer rings are conical and suitable for bearing large loads in both radial and axial directions.

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

Double-row tapered roller bearings are usually used in applications that require large loads and high-speed rotation, such as wind turbines, metallurgical equipment, rolling mills and heavy machinery, etc.

Single course thrust ball bearings: consist of two washers with raceways and balls guided b a cage. Washers have flat seating surfaces, and that is why they need to be supported so that all balls can be evenly loaded. Bearings lift the axial load solely in one direction. They are no longer capable to lift radial forces.Double path thrust ball bearings: have two cages with balls between the central shaft washer and two houding washers with flat seating surfaces.

Axial (Thrust) needle roller bearings are units comprising axial needle rollers and cage assemblies and axial bearing washers with a centring spigot. Axial (Thrust) needle roller bearings are able to accommodate heavy axial loads. They are insensitive to shock loads and provide a high degree of bearing units stiffness within a minimum axial space. They represent unidirectional bearings and can accommodate axial loads acting in one direction only.Using axial (thrust) needle roller bearings, it is possible to make compact bearing units.

Linear bearings with flanges Performance: Linear bearings are a linear motion system produced at a low cost for use with unlimited travel and circular shafts. Because the bearing ball is in contact with the shaft dry point, the load is small. The steel ball rotates with very little friction resistance, thus achieving smooth motion with high precision.Flanged linear bearing series Specification classification :LME, LMK series LMH series LMFP, LMKP series with flanged linear bearing LMHP series with flanged linear bearing LME.LLMK.L series LMH.L series LMFP...

According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same, and it is necessary to carefully check the selection according to the design when using.1 Classification according to the shape of the bearing seat:1.1 Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. 1.1.1.1 The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series.

FAG bearings-Deep groove ball bearings are the most popular of all ball bearing types because they have a variety of seals, dust caps, and stop ring arrangements to choose from. The groove of the bearing ferrule is an arc, slightly larger than the radius ball of the bearing ring.FAG bearings are a very famous brand.

The cone, cup and rollers carry the load while the cage spaces and retains the rollers on the cone. The cone, rollers and cage components of our tapered roller bearings are referred to as the cone assembly.

The structure of one-way thrust ball bearing is relatively simple, mainly composed of outer ring, inner ring, steel ball, cage and cover.The outer ring is the outermost part of the thrust ball bearing, usually made of steel material. The inner ring is located inside the outer ring, and the gap between the outer ring is the movement space of the steel ball. The steel ball is the key component connecting the outer ring and the inner ring, which can provide the function of carrying the thrust load.

In general, INA needle roller bearings have the advantages of high load carrying capacity, high-speed operation, low friction, lightweight and compact, and are widely used in industrial automation, machine tool equipment, automotive transmission systems and other fields.
