GQZ 4208-B-TVH Double Row Deep Groove Ball Bearing 40×80×30mm With Polyamide Cage For Industrial Gear Units

4208-B-TVH is double row deep groove ball bearing. B design represents enlarged ball complement for improved load capacity. TVH refers to lightweight solid polyamide cage. It can bear radial load and moderate bidirectional axial load simultaneously. Compact structure saves installation space compared with two single row bearings. Widely used in small gearboxes, textile machinery, fans and general industrial transmission assemblies.
