Advantages and application of NTN bearing

Advantages and application of NTN bearing

The advantages and application of NTN bearings are as follows

  1. NTN bearing is a representative rolling bearing with a wide range of applications. It is suitable for high-speed or even extremely high-speed operation, and it is very durable and does not require frequent maintenance. Moreover, this kind of NTN bearing has the advantages of small friction coefficient, high limit rotation speed, simple structure, low manufacturing cost and easy to achieve high manufacturing accuracy.This is the advantages and application of NTN bearing.
  2.  The size range and form are varied. It is used in precision instruments, low noise motors, automobiles, motorcycles, general machinery and other industries. It is a widely used NTN bearing in the machinery industry. Mainly bear radial load, but also bear a certain amount of axial load.  
  3. The axial bearing capacity increases when the radial clearance is large, and the contact angle is zero when the radial force is pure. When there is axial force, the contact angle is greater than zero. Generally, punching wave cage, turning solid cage and sometimes nylon frame are used. This is the advantages and application of NTN bearing. 
  4. After the NTN bearing is installed on the shaft, within the axial clearance of the NTN bearing, it can limit the axial displacement of the shaft or the housing in two directions, so it can be axially positioned in both directions. In addition, this kind of NTN bearing has a certain self-aligning ability, and it can still work normally when it is tilted 2 ′ ~ 10 ′ relative to the shell hole, but it has a certain influence on the life of NTN bearing. NTN bearing cages are mostly steel plate stamped wave cages, and large NTN bearings are mostly made of car-made metal solid cages.This is the advantages and application of NTN bearing.
  5. NTN bearings are commonly used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, etc.This is the advantages and application of NTN bearing.
  6. As a kind of high-performance and high-reliability bearing, NTN bearing, with its help , many users can get strong rigidity, durability, low noise and environmental protection. Good performance.This is the advantages and application of NTN bearing.

Advantages of using NTN bearing

  1. NTN bearing has the ability to withstand high temperature, and it will not cause the bearing ball to expand due to the temperature in high temperature environment, which helps the equipment to run better. This greatly increases the service temperature of the whole bearing and prolongs the service life of the bearing products.This is the advantages and application of NTN bearing.
  2.  NTN bearing products are oil-free and self-lubricating, which improves the lubrication efficiency of the products and helps the equipment to be used better. The friction coefficient of NTN bearing is small, so the bearing has a high rotational speed and a relatively high service efficiency. The high lubrication efficiency of NTbearing products can help prolong the service life of products, reduce the lubrication cost of equipment and improve the service efficiency of equipment.This is the advantages and application of NTN bearing.
  3.  Another advantage of NTN bearing is that the product has a long service life and a very high cost performance, which helps users to improve the use efficiency of products and help equipment to produce better. Nt bearing can operate without adding any grease in use, thus avoiding the failure of lubricating oil in ordinary bearings. Long-term use of the lubricating oil of the bearing will also cause damage to the equipment, which can be effectively avoided by using NTN bearings.This is the advantages and application of NTN bearing.
  4.  NTN bearing also has a good insulation effect, which can insulate the inner and outer rings of the bearing, help the bearing to be used in a conductive environment, and expand the application range of the bearing.This is the advantages and application of NTN bearing.
  5. The use value of NTbearing products lies in that it can improve the operation efficiency of equipment, improve the use efficiency of equipment and reduce the friction generated by equipment in production.This is the advantages and application of NTN bearing.
  6. The bearing can bear radial and axial loads at the same time, so the structure of the bearing can be much simpler than that of multiple sets of combined bearings. Because of the high rotation efficiency and low heat dissipation of the bearing, the consumption of lubricating grease is small. The radial and axial dimensions of the bearing can be limited, so the space can be saved, and it can be used in high-precision and high-rigidity occasions with small dimensional requirements in space conditions.This is the advantages and application of NTN bearing.
  7. At present, the application of self-aligning roller bearings is not very extensive in China. In fact, bearings can be used in all walks of life, ranging from machine tools to robot joints, cameras, medical devices and so on.

The function and selection of NTN bearing

Advantages and application of NTN bearing
  1. NTN bearings are mainly used to support and reduce friction in machinery, so the accuracy and noise of NTN bearings are directly related to the use and life of machinery.This is the advantages and application of NTN bearing.
  2.  Generally, the NTN bearing model is selected by the user’s technicians according to the service conditions and load of the supporting products. If the NTN bearing can’t meet the use requirements, it should be recommended to re-select the model as soon as possible, but there is generally no problem in selecting the model unless it is a special product.This is the advantages and application of NTN bearing.
  3. NTN bearing is a high-precision product, and improper assembly can easily damage the NTN bearing channel, resulting in the damage of NTN bearing. Nt bearing should have a special mold during assembly, and it can’t be knocked at will. When it is pressed into the shaft, it can only be stressed in a small circle, and when it is pressed in a large circle, it can only be stressed in a large circle. When assembling, pneumatic or hydraulic pressure is required. When pressing, the upper and lower dies should be in a horizontal state. If there is any inclination, the NTN bearing channel will be damaged due to stress, and the NTN bearing will have a guide ring.This is the advantages and application of NTN bearing.
  4. The service life of NTN bearing is closely related to its manufacture, assembly and use, and every link must be done well to keep the NTN bearing in the running state, thus prolonging the service life of NTN bearing.This is the advantages and application of NTN bearing.
  5. Generally speaking, the seal of NTN bearing is more effective than the dust cover, and it is limited by flexible rotation and low speed rotation. The designer must consider the performance of lubricant, the conveying system and the expected working conditions when selecting the appropriate seal.This is the advantages and application of NTN bearing.
  6. Sliding bearings are used in high-speed or low-speed precision and high-precision CNC machine tools because of their good vibration resistance, high rotation accuracy and smooth movement.This is the advantages and application of NTN bearing.7.Under the action of periodic load, the contact surface of the bearing is easily exhausted and damaged, that is, cracking and peeling appear, which is an important damage situation of the bearing. Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.During the bearing task, not only rolling friction, but also sliding friction will occur between the ferrule, the rolling body and the support frame, which will make the bearing parts wear all the time. In order to increase the wear of bearing parts, maintain the stability of bearing precision and extend the service life, bearing steel should have good wear resistance.Hardness is one of the important qualities of bearing quality, which has indirect influence on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel in service should reach HRC61~65 individually, which can make the bearing obtain higher contact fatigue strength and wear resistance.
