Description

● Introduction



6024 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. Bearing clearance is an important technical parameter, it directly affects the bearing load distribution, vibration, noise, friction, service life, mechanical movement accuracy and other technical performance. The dynamic load rating of bearing varies with the amount of clearance. Bearing rated load is the value of the load when the working clearance of the bearing is zero. The material of bearing cage is 08Al. The cage is generally made of steel plate by stamping at normal temperature with the use of mold, and the shape, dimensional accuracy and surface quality of the cage can be guaranteed by stamping molding processing. Bearings are widely used in motorcycles, automated office machinery, precision instruments, pumps, roller skates and other fields.


Production Details



The process type of press forging ring forgings can be divided into extrusion process, extrusion rolling expansion (plastic) process, set forging rolling expansion (plastic) process, tower extrusion rolling expansion (plastic) process and free punching rolling expansion (plastic) process 5, after rolling expansion, if you increase the plastic process, can further improve the quality, accuracy and productivity of forgings. The quality of double endface grinding includes two categories: machining accuracy and surface quality. In machining accuracy, the main quality indicators are the variation of collar width, perpendicularity such as S (the variation of the inclination of the outer diameter surface bus to the reference endface) and the size of the grinding margin on both endfaces, and in surface quality, the main ones are surface roughness and surface burns. Defects in the forging process include defects arising from heating and internal and external defects during processing. Defects arising from heating are oxide, oxide not only loses a lot of steel, but also reduces the surface quality of forgings and the service life of forging dies, if pressed into the metal inside, resulting in scrap forgings. Do not remove the oxide skin will affect the turning process.

Quality Standards



Bearing clearance is not the larger the better. If the clearance is too large, bearing rotation will produce vibration and noise, but also make the internal load distribution deterioration, early damage. Therefore, the selection of clearance must be appropriate and just right.

Noise and Vibration



Divided into V, V1, V2, V3, V4 five quality levels. Various ball bearings quality level from low to high for V, V1, V2, V3, V4; roller bearings (cylindrical, tapered) quality level from low to high for V, V1, V2, V3 four quality levels. It is to detect the vibration speed of the bearing in different frequency bands to reflect the quality of the bearing. It can roughly analyze whether there are geometric dimensional problems, quality problems of raceways/rolling bodies, quality problems of cages in bearings, which is a significant progress than examining the quality of bearings by vibration acceleration.
