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.

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.

High load carrying capacity    The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers  High stiffness    The increased number of rollers increases radial stiffness.    High speed capabilityThe cage designs are suitable for high speeds, rapid accelerations and peak loads.  Long service life  The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:     

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.

The design of the roller and raceway contact line of all thrust cylindrical roller bearings is optimized to avoid the generation of edge effects.

1.Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations, which can withstand heavy loads and vibration loads without difficulty.2. this kind of bearing can bear a large axial load in a single direction, but can not bear radial load, they do not have automatic aligning ability.3. the thrust cylindrical roller bearing can be divided into thrust cylindrical roller and cage assembly, shaft ring and seat ring.4.

Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations that can withstand heavy loads and vibration loads without difficulty. Such bearings can withstand large axial loads in a single direction, but they cannot withstand radial loads, and they have no automatic aligning capability.

Applications: Cross roller bearings are widely used in many fields, including machine tools, engineering machinery, medical equipment, food packaging machinery, etc. On machine tools, cross roller bearings are often used to support the spindle and the turntable to ensure the high-speed and high-load operation of the equipment.

Linear motion bearings have the characterized of smooth movement,low friction,high rigidity and long life span,economical and easy to maintain or replaceMotorized linear slides such as machine slides, XY tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand.

1.Needle roller bearings for stamping outer rings. There are two kinds of bearings: perforated type and sealed type. The needle roller bearing has no inner ring, and the needle roller directly contacts the surface of the shaft, so the processing accuracy and heat treatment hardness of the shaft should be the same as that of the bearing inner ring.2. Solid ring needle roller bearings solid ring needle roller bearings, commonly used solid ring needle roller bearings are NA type and RNA type.3. Roller needle bearing4. Needle roller and cage assembly.

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.

Even if the production of the motor is strictly controlled during the manufacturing process, it is difficult to completely avoid the magnetic asymmetry of the armature and rotor. This asymmetry creates a voltage between the stators, which creates a current through the bearings, especially in AC motors. This current will cause corrosion pits, melting marks, electrical corrosion file lines and discoloration, wear and other damage on the bearing raceway and rolling surface.

Product Description:For some industrial products with high moisture and oxidation requirements, such as precision mechanical parts, electronic products, etc., 3003 aluminum alloy coil can be used to make packaging materials.

Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy loadRolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down.

Loaders: Loaders are used to load and unload various materials, and their working conditions require the wear and impact resistance of bearings. Cylindrical roller bearings or bi-directional thrust ball bearings that are resistant to high speed work are usually used on loaders.Cranes: Cranes are used to lift and move heavy goods and are required to withstand high tensile and compressive loads.

First of all, one of the characteristics of FAG deep groove ball bearings is a simple structure, consisting of an outer ring, an inner ring, a steel ball and a cage. This simple structure makes the installation and maintenance of deep groove ball bearings more convenient and fast.Secondly, the bearing capacity of FAG deep groove ball bearings is large and can withstand both radial and axial loads.

The separation bearing is composed of a racetrack ring, a needle roller and a cage assembly, and can be used in any combination to thin or thick racetrack rings. The non-separable bearing is an integral bearing composed of precision stamped raceway ring, needle roller and cage assembly that can withstand unidirectional axial loads. This bearing occupies a small space, which is conducive to the compact design of the machine.
