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.

NSK automotive hub bearing is a key component used to support the rotation of automotive wheels. It uses high-quality bearing steel materials and advanced manufacturing processes to ensure the durability and performance stability of the bearing. NSK automotive hub bearings are usually composed of inner and outer rings, bearing balls (rollers), cages, sealing rings, etc. They can withstand the weight of the vehicle, reduce friction, improve rotation efficiency, and resist vibration and impact forces to ensure safety and stability when the vehicle is running.

The deep groove ball bearing with dust cover and sealing ring has been filled with appropriate grease during assembly, and should not be heated or cleaned before installation. No further lubrication is required during use, and the operating temperature is between -30 ° C and +120 ° C.NSK deep groove ball bearings generally consist of two bearing rings with complete raceways. The rolling element is mounted between the rings and rolled on the raceway. The rolling parts can be balls, cylindrical rollers, needle rollers, tapered rollers, or barrel rollers.

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:     

Hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings, it will be two sets of bearings as one, with good assembly performance, can be omitted clearance adjustment, light weight, compact structure, large load capacity, for sealing bearings can be loaded in advance grease, omit the external hub seal and free from maintenance and other advantages, has been widely used in cars, There is also a trend of gradual expansion of applications in heavy-duty vehicles.1.

The ball screw pair has the characteristics of high precision, reversibility and high efficiency, which is the further extension and development of the ladder screw, and the important significance of this development is to change the sliding action of the ladder screw into a rolling action.

Advantage of 7020C BearingWhen using the bearing, pay attention to make the raceway on one side without ball loading notch bear the main load.The locking port of this kind of bearing is on the outer ring.Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial load and the axial load in one direction.The ability to bear axial load is determined by the contact angle.The larger the contact angle, the higher the ability to bear axial load.Angular contact ball bearings are mainly divided into single row angular contact ball bearings and double row angula

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.

The main role of wheel bearings is to bear the weight and provide precise guidance for the rotation of the wheel, which is subject to both axial and radial loads. Traditionally, bearings for automotive wheels are made of two sets of tapered roller bearings or ball bearings combined, and the mounting, oiling, sealing and clearance adjustment of the bearings are carried out on the automotive production line.

The structure of the thrust roller bearing is generally composed of an inner and outer ring, a thrust roller, a cage and a sealing ring. The inner and outer rings are annular structures, which are installed on the shaft and the housing to carry the axial load. The thrust roller is cylindrical or conical, arranged between the inner and outer rings, and can effectively withstand and transfer the axial load. The cage is a structure that supports and holds the thrust roller, usually made of steel or copper.

During use, CAM bearings need to pay attention to maintenance and maintenance to ensure their normal operation and extend their service life. It is important to keep the camshaft surface clean to avoid dust and impurities entering the bearing parts. Regular oil changes are also essential to maintain good lubrication between the camshaft and the bearing.The role of CAM bearings in the engine is crucial. A high quality CAM bearing can effectively reduce friction and wear, improve engine performance and efficiency.

The main role of automobile hub bearing is to load and provide accurate guidance for the rotation of the hub, which is a very important component to bear both axial and radial loads. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are carried out on the automobile production line.

Cam Follower Needle Roller Bearings are also referred to as track follower. They are designed to follow a sliding or rotating piece (cam) and they use rollers or needles as the rolling elements. Cam Follower Bearings are therefore able to replicate a specific motion because they are highly versatile. They have thick-walled outer rings that run on a track.

Tapered roller bearings are widely used in various mechanical fields, such as automobiles, aviation, machine tools, etc., because of its large bearing capacity, high precision, good reliability and other advantages, it has been widely concerned and applied in the industrial field.

The standard drive system for stud CAM follower is usually a slot, suitable for flat head screwdrivers. However, for some special cases, such as eccentric CAM follower or where higher torque capacity is required, the socket can also be used in the drive system. The hex socket has a larger contact area and can withstand greater torque, so it is very useful for some applications with higher loads, especially for those that need to be driven in blind holes.

The important construction modes of the turntable bearing seat are: four-point contact ball bearing seat, double-row angular contact thrust ball bearing seat, interpenetrating cylindrical roller bearing seat, interpenetrating tapered roller bearing seat, and three-row cylindrical roller with turntable bearing seat.According to whether the gear can be carried and the spread of the gear is divided into: toothless, external or internal gear and other different structures.The four-point contact ball turntable bearing seat has a higher static bearing capacity, the interspersed cylindrical roller be
