SKF Bearings-Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.The bearing ring grooves are circular arcs made slightly larger than the radius of the ball.
Application :
They are widely used in metallurgy, power, petrochemical, construction machinery, railway, steel, papermaking, cement, mining and other industries. They are widely used of vehicles, motorcycles, home electrical appliances, electric tools and mineral machineries.
In accordance with the sizes of deep groove ball bearings can be divided into :
(1) miniature bearings ---- nominal diameter size range of 26mm bearings;
(2) small bearing ---- nominal diameter size range of 28-55mm bearings;
(3) small and medium-sized bearings ---- nominal diameter size range of 60-115mm bearings;
(4) large bearing ---- nominal diameter size range of 120-190mm bearings
(5) large bearing ---- nominal diameter size range of 200-430mm bearings;
(6) ---- large bearing diameter size range of 440mm or more bearings.
