Method Of Limiting Nsk Bearing Life From Wear

Limiting Nsk Bearing 

Grinding burns and grinding cracks are not allowed on the finished Limiting Nsk Bearing bearing ring, especially on the mating surface of the inner ring with taper change. If the ferrule is pickled, it shall be fully inspected to remove the burned products.

The severely burned ones cannot be repaired or the unqualified ones shall be scrapped. The ferrule with grinding burn is not allowed to enter the Limiting Nsk Bearing assembly process After the steel is put into storage and before the ferrule grinding, each process must be strictly managed to strictly distinguish GCr15 and GCr15SiMn materials and products

Whether NSK bearing can be judged is based on the degree of damage to be considered according to various Limiting Nsk Bearing needs. In this regard, the main consideration is the effect of damage. For mechanical performance, importance and installation conditions, they need to be considered until the next maintenance period.

However, for the case that the defect cannot be used, it must be replaced with a new bearing. For the inner ring Pay attention to any crack notch on the outer ring, rolling element and Limiting Nsk Bearing cage, which is also an effect of maintenance in this regard. So there are skills in the sense. Here are the eight points to introduce the rules.

Method Of Limiting Nsk Bearing Life From Wear

After bearing load, the rolling bearing produces plastic deformation at the contact between rolling element and raceway.

When the load is too heavy, plastic deformation pits will be formed on the raceway surface, resulting in strong Limiting Nsk Bearing vibration and noise of NSK bearing in summer.

Due to the relative movement of the rolling element and the raceway and the invasion of dirt and dust, the Limiting Nsk Bearing surfaces of the rolling element and the raceway are worn.

When the wear is large, the bearing clearance, noise and vibration increase, which reduces the operation accuracy of NSK bearing, thus directly affecting the accuracy of some main Limiting Nsk Bearing engines. Therefore, for some NSK Bearings Used in precision machinery, the wear amount can be used to limit the service life of NSK Bearings.

A method to improve the accuracy of fag bearing

A precision instrument is trial produced in a factory. The main shaft uses 6202 / P2 bearing, but its accuracy still can not meet the requirements. After that, the journal is thickened and a raceway is made on it to replace the inner ring, and the steel balls are accurately measured.

Each group of steel balls is divided by three particles in size, and each group of steel balls is separated by an interval of nearly 120 °. Due to the reduction of one heavy machining surface and one heavy fitting surface,

At the same time, the stiffness of the shaft bearing system is improved, and the nearly equidistant distribution of large three particles and small three particles improves the rotation accuracy of the shaft, so it meets the accuracy requirements of the instrument.
