● Introduction



6209 ZZ bearing belongs to single row deep groove bearings. It is produced by our company in accordance with the national standard GB/T 276-2013, and the bearing‘s groove is super-finished. The company is committed to providing customers with stable and competitively priced high quality bearing products. The precision grade of the bearing conforms to the standard GB/T 307.3-2017. The precision grade of the bearing is P0,P6,P5,etc. Choosing the corresponding precision grade of the bearing according to the use environment and requirements. The bearing mainly bears pure radial load, the load is mainly carried from one ring to another through the rolling element. The value of bearing load and design parameters are related to the type of bearing load. Bearings are widely used in motorcycles, industrial pumps, transmissions, motors and other fields.


Production Details



Tempering of the ring, the quenched steel heated to a certain temperature, holding a certain time after cooling to room temperature heat treatment process is called tempering. The purpose of tempering is to reduce the quenching stress to prevent cracking, stabilize the organization, thereby stabilizing the size and improving toughness. The theory of rounding in external centerless grinding is to study under what conditions the workpiece becomes more round as it is ground. Due to the unevenness of the workpiece surface, it is not theoretically round. If more metal is ground away from the workpiece in a few starting parts, i.e., the workpiece moves a little more distance to the grinding wheel, and a little less is ground away from the workpiece in the crater part, even if the workpiece turns its back to the grinding wheel, so that the workpiece becomes more round. Bearing steel internal defects are mainly shrinkage, bubbles, white spots, overburning, loosening and segregation, etc. In addition to mild loosening and segregation are allowed to exist, other defects are not allowed to appear. External defects mainly refer to surface slag, cracks, burrs, folding, scars and thick oxide skin, these defects are not allowed to exist.
