GQZ 6930 C3 Thin Section Deep Groove Ball Bearing 150×210×28mm For Precision Automation Equipment
6930 C3 belongs to thin-wall 69 series single row deep groove ball bearing. C3 represents larger-than-standard radial internal clearance. Ultra-slim radial cross-section effectively reduces overall structural size. It can bear radial load and minor bidirectional axial load simultaneously. Stable rotation with low friction characteristic. Widely applied in precision automation equipment, textile machinery, packaging machinery, robot auxiliary joints and light-duty rotating assemblies with limited installation space.
