Nov 22, 2017 · In each application, the grit size, the hardness grade and the structure of the grinding wheels are dependent on the ball size. For example, for small balls (4-9 mm) grit sizes between 200 and 280 (FEPA-F) are recommended, while grit sizes between 120 and 150 (FEBA-F) are better for big balls (60-80 mm).


MANUFACTURING BEARING BALLS Steel balls produced for the bearing industry are often made in standard bearing steel 100Cr6 – AISI 52100 (HRC = 60-66) and are produced through a standardized process, of which grinding is a key operation. The diameter of balls range from very small (0.05mm) to large (300 mm), with a majority of 20-30mm. RAW MATERIAL

How ball bearing is made - manufacture, making, used ...

This article will describe only ball bearings. In these bearings, the rolling part is a ball, which rolls between inner and outer rings called races. The balls are held by a cage, which keeps them evenly spaced around the races.

Race (bearing) - Wikipedia

In the case of ball bearings, the bearing has inner and outer races and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point.


pressures of grinding bearing balls, ball grinding wheels are ex-tremely hard. Available in both vitrified and resin bond systems with aluminum oxide and silicon carbide blends, each specifi-cation is tailored to specific customer requirements. Machine Ball grinding is done on specially designed machines with horizontal or vertical axis.
