Deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and very high speeds and are robust in operation, requiring little maintenance. SKF single 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. Specifications: Dimension Standards: ISO 15. Tolerances: ISO 492. Internal Clearance: ISO 5753-1. Permissible Misalignment: ≈ 2 to 10 minutes of arc. Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline values these effects become particularly noticeable. Inner Diameter: 65 mm Outer Diameter: 120 mm Width: 23mm Contact Seals: Made of sheet steel reinforced NBR.
