Needle roller bearing is a common mechanical part, which is mainly used to support the movement of the rotating shaft. The working principle of the needle roller bearing is to use the rolling body (needle roller) to roll between the inside and outside, thereby reducing friction and resistance, so that the bearing can withstand larger loads and rotational speeds.The structure of the needle roller bearing is relatively simple, consisting of an inner ring, an outer ring, a needle roller and a cage.

The outer ring double guard (or double lock ring) with cage needle roller bearing NA, NKI type, can be installed respectively inner ring and outer ring (with lock ring, a full set of needle roller and cage), high speed, divided into single and double row two. Such needle roller bearings with inner rings may be used if the shaft cannot be used as a raceway, i.e.

Rotary bearing is an important mechanical component, which is widely used in various industrial equipment and mechanical devices. It bears the radial load, axial load and moment load under the rotating motion, and plays the role of support and rotation. The following will introduce the structure, working principle, application field and maintenance of the rotary support bearing in detail.Rotary support bearings are usually composed of an inner ring, an outer ring, a rolling element (ball, roller, etc.) and a cage.

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.

Needle roller bearing is a common rolling bearing, using needle roller as the rolling body, can withstand the radial and axial load.Structure: Needle roller bearings are mainly composed of outer ring, inner ring, needle roller, cage and seal. The shape size of the needle roller bearing is small, saving space, suitable for limited space design.

IKO's needle roller bearings have high bearing capacity and fatigue resistance, can run stably for a long time, extend the service life of the equipment, reduce the frequency of maintenance and replacement of bearings, reduce the maintenance cost of the equipment, and improve the reliability and stability of the equipment.IKO's needle roller bearings are widely used in various industrial equipment and mechanical devices, such as automobile engines, aircraft engines, high-speed trains, construction machinery, agricultural machinery and other fields.

Structural features: The roller inside the cross roller bearing is combined in a cross arrangement, which makes the bearing able to withstand both radial and axial loads. There is a certain gap between the inner and outer rings, which can make the bearing maintain high rigidity when it is subjected to high torque load, and also has good rotation accuracy and stability. The design of the seal ring and cage of the cross roller bearing is also very important, which can effectively prevent dust and foreign matter from entering the bearing interior and extend its service life.

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.

Combined needle roller bearings, a special type of bearing, can be added between the inner and outer rings of the needle roller components to achieve balance accuracy, reduce vibration and noise effects.

Rolling bearing with seat is a common and widely used in various mechanical equipment bearings, which support and transmit rotating motion through rolling elements, with high load capacity and stability. Below I will describe in detail the structure, working principle and application areas of rolling bearings with seats, hoping to help you better understand this knowledge.A rolling bearing with seat is usually composed of several basic parts, such as an inner ring, an outer ring, a rolling element (such as a steel ball, roller, etc.) and a cage.

The working principle of needle roller bearings is to use rolling friction to reduce friction and resistance. When the bearing is subjected to axial or radial load, the needle roller rolls between the inner and outer rings, thereby reducing friction and resistance.

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.

Needle roller bearings are equipped with thin and long rollers (roller length is 3 to 10 times the diameter, the diameter is generally not greater than 5mm), so the radial structure is compact, its inner diameter size and load capacity are the same as other types of bearings, and the outer diameter is the smallest, especially suitable for radial installation size limited support results.

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.
