● Introduction



6203 long life bearing is single row deep groove bearing. The bearing is characterized by high precision, high speed, low noise and long life. Bearings are mainly subjected to pure radial load, and can also be subjected to radial load and axial load at the same time. Due to the existence of radial clearance of the bearing, the actual contact angle will be increased under the axial load, so the variation of contact angle should be considered when determining the axial load capacity. The bearing has small friction coefficient and high limiting speed. The noise of the bearing conforms to the national standard JB/T 7047-2006. The noise level of the bearings is divided into Z,Z1,Z2,Z3 and Z4. The common bearing is ZV group, and the common motor should generally reach Z1V1~Z2V2. Bearings are widely used in low-noise motors, motorcycles, automobiles, internal combustion engines, gearboxes and other fields.


Production Details



Annealing organization is also allowed to be evaluated at 450~600 times, but the effect of magnification should be taken into account. The etching agent is 2% nitric acid alcohol or 5% bitter alcohol solution. Check the longitudinal and lifting wedge of the tool holder when turning the collar, especially the lifting wedge, to be properly tightened, but not too tight, otherwise there will be "crawling" phenomenon. Check whether the taper of the wedge iron is suitable and whether it is in full contact with the guide rail, so that it is even and in full contact. Check whether the components of the lifting cylinder are tight, and check the tightness of other components such as the tool clamp. The soft grinding end face of the collar is generally processed with a single-head vertical axis surface grinder or a double-head surface grinder, and the processing efficiency is high with a double-end grinder. Demagnetization cleaning and quality inspection should be performed after grinding.

Noise and Vibration Level



Vibration of the rolling element. After bearing load, rolling body in the rotation, due to the location of the load changes, contact parts of different elastic deformation and vibration. The larger the radial clearance, the greater the vibration of the bearing; the number of rolling body increases, the vibration value will be reduced, and the vibration will increase at high speed.
