30X47X17Mm Needle Roller Bearings-manufacture,factory,supplier from China

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.

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.

IKO is a well-known manufacturer specializing in the production of various types of needle roller bearings, and its needle roller bearing products enjoy a high reputation around the world. IKO's needle roller bearings have a variety of excellent characteristics, and the following will describe the characteristics and applications of its needle roller bearings in detail.First of all, IKO's needle roller bearings are made of high-quality materials, have extremely high wear resistance and corrosion resistance, and can operate stably in a variety of harsh environments.

Strong bearing capacity: Due to the large number of needle roller, needle roller bearings have a high bearing capacity, suitable for bearing large radial and axial loads. (2) Small starting torque: the friction inside the needle roller bearing is small, and the starting torque is small, making the starting speed of the bearing faster. (3) Simple structure: The structure of needle roller bearings is relatively simple, easy to install and maintain, and low cost.

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.

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.

One of the largest aspects of the needle curler bearing is the sketch of the needle roller. The needle roller has a smaller diameter than different sorts of rolling elements, so it can obtain a greater load carrying capability in a constrained space.

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.

Secondly, IKO's needle roller bearings are compact in structure, light in weight, easy to install, simple and stable in structure, which can effectively reduce the overall size and weight of mechanical equipment, improve the work efficiency and flexibility of mechanical equipment, and are suitable for various axial and radial loads.In addition, IKO 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 t

One of the biggest features of the needle roller bearing is the design of the needle roller. The needle roller has a smaller diameter than other types of rolling elements, so it can achieve a higher load carrying capacity in a limited space.

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.

1.KR design cam followers are fitted with a needle roller and cage assembly. They are also available with a full complement needle roller set, which is identified by the letter V at the end of the basic designation.

INA needle roller bearings have excellent quality and performance and are widely used in various industrial fields. It uses needle roller as the rolling body, compared to ball bearings, needle roller bearings have higher load capacity and smaller dimensions, suitable for limited installation space.

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.

Founded in Meguro-ku, Tokyo, THK pioneered the development of linear motion systems in the world with creative ideas and unique technologies. THK linear bearings are now more and more widely used in electronics, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles and other general or special machinery industries.Needle roller CAM guideThe needle roller CAM guide is a compact bearing with a high internal rigidity shaft and a built-in needle roller bearing.

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.

Conical roller bearing is a common mechanical transmission element, mainly used to carry axial and radial loads and can achieve rotation and swing motion. It is mainly composed of an inner ring, an outer ring, a roller and a cage, with large carrying capacity, low friction, suitable for high-speed rotation and high accuracy requirements, so it is widely used in construction machinery, automotive, aerospace, mining machinery, metallurgical equipment and other fields.

1. good assembly performance, and clearance adjustment can be omitted.2. light weight, compact structure and large load capacity.3. in order to seal the bearing, the lubricating grease can be installed in advance, the external hub seal can be omitted and the maintenance can be avoided.4.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.

Mainly bear a large unidirectional axial load, the greater the contact Angle, the greater the load bearing capacity. The cage material is steel plate, brass or engineering plastic, and the forming method is stamping or turning, depending on the bearing form or use conditions.

1: High load capacity and accuracyThe internal structure of the bearing is the same as that of the single row deep groove ball. While bearing a large radial load, it can bear axial loads in both directions.The accuracy of the bearing is the same as that of the general accuracy, and it has high rotation accuracy and good high-speed performance2: reasonable aligning structure and the most suitable cooperationThe bearing assembly has the aligning property through the spherical outer diameter bearing and the bearing seat with the spherical inner hole.

In industrial manufacturing and various mechanical equipment, rolling bearings with seats are widely used in heavy machinery, automobiles, aerospace, railway traffic and other fields. For example, in the automotive industry, rolling bearings with seats are used in engines, transmissions, steering systems and other components to support and transmit rotating forces.
