This listing is for 2 piece/s.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: 6 mm Outer Diameter: 19 mm Width: 6mm Shields: Primarily intended for applications where the inner ring rotates. Fitted in the outer ring and form a narrow gap with the inner ring Made of sheet steel. Available as standard with an extension in the shield bore. Protect from dirt and debris without friction losses.
