According to the classification principle of rolling bearing manufacturing shape size

According to the classification principle of rolling bearing manufacturing appearance size source: bearing | last updated: - 2020 09 - 08, according to the classification principle of rolling bearing manufacturing appearance size: 1, the miniature bearing - — Nominal diameter size range D < 26 mm bearing; 2, small bearings - — Nominal diameter size range of 26 D or less < 60 mm bearing; 3, small and medium-sized bearings - — Nominal diameter size range for 60 D or less < 120 mm bearing; 4, large bearing - — Nominal diameter size range for 120 D or less < 200 mm bearing; 5, large bearing - — Nominal diameter size range for 200 D or less < 400 mm bearing; 6, oversize bearings - — Nominal diameter size range 400 D or less < 2000 mm bearing; 7, large bearing - — Nominal diameter D size range of 2000 mm or more bearings; The characteristics of the rolling bearing manufacturing: small friction coefficient, less energy consumption, high mechanical efficiency. Mixer dimension has been standardized and interchangeable, installation, disassembly, and d is very convenient; Axial structure is compact, has greatly reduced the axial size of machine; High precision, wear small, long service life, and in a relatively long time insourcing a hold shaft installation accuracy; With automatic self-aligning bearing features, when the main shaft deflection or slightly with a closed parts can still work normally when different heart; Specialization of mixer is suitable for mass production, the quality is stable, reliable, high production efficiency, low cost.
