● Introduction
6203 ZZ ball bearing belongs to single row deep groove bearings. The bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cage. The material of the bearings is GCr15, which has structural and dimensional stability and is capable of stable performance at the required working temperature. Bearing cage is used to isolate the rolling element, guide the rolling element and keep it in the bearing. The material of bearing cage is 08Al. The cage is generally made of steel plate by stamping with mold at normal temperature, the stamping cage has high strength, and the surface treatment can reduce the friction wear. Bearings are widely used in internal combustion engines, instruments, agriculture, motorcycles and other fields.
● Production Details
Ring blank final forging temperature is too high, coarse grains, precipitation of carbide in the cooling process, if the cooling rate is too low will form a coarse carbide network, reducing the strength of steel. The final forging temperature is as low as 800℃, the carbide precipitated along the grain boundary will be elongated along with the grain in the deformation process and form stripes, which will cause the strength of the steel to drop sharply. High-precision cylindrical collar profile sample cutter and carbide mechanical clamping type cutter are widely used in bearing turning processing. As well as carbide prism sample cutter and circular machine-clamped carbide dental cutter for sealing groove, etc., all have many advantages and play a good role in stabilizing machining quality, improving productivity and reducing machining cost. In addition, carbide tools with coating have been developed recently to improve tool life. Although the reaming process can get high precision forgings, the consistency, roundness and cylindricity of collar size are still not good enough for automatic clamping of turning process due to the accuracy of billet feeding, rolling and reaming temperature, rigidity and adjustment of reaming machine, etc. Nowadays, it is common to add a shaping process after rolling and expanding process to correct the geometric deviation such as roundness and cylindricity and unify the inner and outer diameter size through the whole outer diameter or inner diameter.
