● Introduction



6208 ZZ high precision bearing is single row deep groove bearings. It is produced by our company in accordance with the national standard GB/T 276-2013. The company is equipped with advanced processing and testing equipment, equipped with professional testing department and has a perfect quality control system to ensure the material, dimensional tolerance, clearance, noise and vibration of the bearings meet the standards. The material of bearing cage is 08Al, and the cage is generally made of steel plate by stamping at normal temperature with a mold. The processing of stamping cage generally includes punching, bending, stretching, forming and other processes. The precision grade of bearings conforms to the standard GB/T 307.3-2017. The precision grade of bearing is P0,P6,P5,P4 and P2. The P0 grade bearings can meet most of the applications, the P5 grade bearings are generally precision bearings, the P4 grade bearings are high precision bearings. The P2 grade bearings are ultra-precision bearings, such as those used in machine tool spindles, disk drive spindles, precision instruments, etc. 

Bearings are widely used in tractors, household appliances, construction machinery, pumps, transportation vehicles, industrial pumps and other fields.


Production Details



◆ Cold treatment process after quenching of workpiece, cold treatment insulation, although the transformation of the largest most martensite is completed in a moment when cold to a certain temperature, but for a batch of collar surface and heart are uniformly reach the cold treatment temperature, need a certain insulation time, generally 1 ~ 1.5h. Carburizing equipment for bearing parts, extra-large bearing parts are produced by large scale inlet type gas carburizing furnace. Small batch production of rolling body can use multi-purpose furnace or well gas carburizing furnace processing. Small and medium-sized rolling body can use rotary furnace carburizing. The choice of the grinding bond is mainly related to the grinding method and the quality of the processed surface. The choice of hardness is mainly determined by the material of the workpiece to be ground and the grinding method. It is more common to choose medium-soft hardness grinding wheels.

◆ Suitable for medium and small batches and single piece production, easy to organize production, simple and economic lathe, jigs and fixtures, easy to change bearing type, low cost. If a single machine is connected into an automatic line, it is also suitable for mass production; it can be processed by a special lathe with good rigidity and high power, which is easy to select the best industrial parameters and can be used for high speed cutting with large cutting tools.

Bearing Quality



Cracks in raw materials, forging cracks, heat treatment cracks, grinding cracks, etc. will become a source of stress concentration and expand rapidly during the subsequent operation of the bearing, causing the bearing to rupture and affecting its service life and work safety. In fact, for the important use of bearing products, bearing manufacturers will be 100% magnetic or radiographic flaw inspection of its component parts.

Noise and Vibration



The sources of bearing noise are mainly the following: one is caused by the inherent factors such as the structure type of the bearing, original clearance, cage shape and the number of rolling bodies: another is caused by various defects in the manufacturing of bearing parts (such as the ripple degree of the working surface of the collar and rolling body, geometric shape deviation or residual magnetism, etc.), which causes impact when the bearing is running: another is caused by improper installation and use, such as The installation process is unreasonable, the choice due to improper installation and use, such as: installation process is unreasonable, choose the type of fit is not appropriate, bearing clearance is too small, cleaning is not clean, etc. For general purpose bearings, usually in the inspection of rotational flexibility at the same time to check the noise, the test method is also the same as the inspection of rotational flexibility.
