NTN Bearing

We should check the surface of NTN imported bearing before using it, thus determining whether the bearing can meet our requirements and standards. The examination of bearing surface should be operated in astigmatism lamp, and we need to make a detailed inspection on the rift and surface of the bearing.

Problems and Solutions of NTN Bearing
We can use sound measuring device to reflect the rolling sound and quality of sound of NTU bearing even when bearing has minor stripping and other damage, and the sound measuring device can also distinguish abnormal sound and uneven tone.

Bearing vibration is very sensitive to the bearing damage, such as spall, indentation, corrosion, abrasion and crack of bearings. Therefore, we can use the NTN bearing vibration measuring device to measure detailed information of vibration and speculate the abnormal status. The measured value varies due to the differences of the use of bearing or sensor installation position, thus demanding a discrimination criterion before measuring.

The normal temperature of bearings varies due to the differences of mechanical heat capacity, heat flux, speed and load. Generally, bearing temperature rises along with the operation of bearing and remains in unchanged form after 1-2 hours. Thanks to the influence of smoothness, speed and load on temperature, NTN bearing has a limited range of temperature. Thermal sensor can monitor the bearing working temperature at any time and alarm actively or suspend bearing operation when the temperature exceeds the limited temperature.

Lubrication has important implications on the fatigue life and friction, wear, temperature and vibration of NTN imported bearing. Bearing will not work if there is no normal lubrication. The analysis of damaged bearings shows that about 40% of the damaged bearings have poor lubrication. Therefore, good lubrication of bearing is an effective measure to reduce friction and wear.

Main Products
  • NUP Type Cylindrical Roller BearingThe outer ring of NUP type cylindrical roller bearing has double outer walls while the inner ring has one fixed inner wall and the other is detachable flat ring. It can endure a certain amount of bidirectional axial load. The product can limit the axial displacements of two directions between the axle and bearing block, thus applying to be used as a stationary end bearing. NUP type cylindrical roller bearing has large radial load capacity and is applicable to bear heavy load and shock load. It is line contact between the roller and raceway
  • Full Complement Cylindrical Roller BearingFull complement cylindrical roller bearing is designed to bear heavy load. In the same width, the bearing has superhigh bearing capacity and small radial section and it can save space, but its speed is relatively low. In order to make the bearing working normally, the product must be subjected to a certain minimum load, namely C/P < 25, in continuous operation condition. Otherwise it will aggravates wear because of lack of lubrication and high speed operation. All multi-row cylindrical roller bearings has a lubricating groove ...
