698zz bearing high precision miniature bearing 698ZZ Dimensions 8x19x6mm

698zz high precision miniature bearing 698ZZ dimensions 8x19x6mm, types are manufactured with metal shields inserted into the outer raceway, these fit in closely to the inner race providing protection against light mechanical damage, some protection against the ingress of moisture, dust and other foreign matter and serve to retain the pre-filled grease in the bearing.

• Metal Shielded Miniature Ball Bearing has an inside diameter of 8mm, an outside diameter of 19mm, and a width of 6mm.
• miniature ball bearing with smallest dimensions
• suitable for high radial loads and light axial loads in both directions
• suitable for high running accuracy, quiet running and very high speeds
• seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z) for higher speeds than with rubber seal
• good fixed bearing property, but can also be used as a floating bearing, each in both directions
