Double Row Deep Groove Ball Bearings 4308 are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate. For the same bore and outside diameter, double row bearings are slightly wider than single row bearings in the 62 and 63 series, but have a considerably higher load carrying capacity. Double row bearings have deep, uninterrupted raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions.
Applications and Industry: AGRICULTURE, AUTOMOTIVE, CEMENT INDUSTRY, CRUSHER INDUSTRY, HEAVY MACHINERY EQUIPMENTS, HOME APPLIANCES, MINING SECTOR, METAL INDUSTRY, FLUID MACHINERY, TEXTILE INDUSTRY
