Product Details
SKF
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).
Suffixes
2RS1 - Contact seal, NBR, on one or both sides
2Z - Shield on one or both sides
C3 - Radial internal clearance greater than normal
2RZ - Non-contact seal, NBR, on one or both sides
