634-2Z DEEP GROOVE BALL BEARING

Self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products are of simple design, durable in operation and easy to maintain. Shielded type with metal shields inserted into the outer raceway, these fit in closely to the inner race providing moderate protection against mechanical damage, and against the ingress of moisture, dust and other foreign objects. The shields also retain the pre-filled grease in the bearing. Shields can be easily removed for applications that only require one shield. Also available are open and rubber sealed types.
