SKF 61904-2RZ Single Row Deep Groove Ball Bearing- Non Contact Seals On Both Sides 20mm I.D, 37mm O.D

Deep Groove Ball Bearings

Deep groove ball bearings are versatile. They are simple in design, non-separable, suitable for high speeds and are robust in operation, requiring little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes.

Product Application Information

SKF single and double row deep groove ball bearings have deep, uninterrupted raceway grooves. These raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions.
Single row deep groove ball bearings are available open or capped (with seals or shields).
Double row deep groove ball bearings are only available as open bearings (without seals or shields).
