China wheel ball roller rolling bearing 6300 series high precison Centrifuge Axle bolt CNC punch deep groove ball bearings

Deep groove ball bearings are the most widely used and representative rolling bearings. The raceways of the inner and outer rings of this type of bearing are arc-shaped deep grooves, which can bear radial, axial and composite loads. Simple structure, easy to obtain high precision, suitable for high-speed rotation.

Deep groove ball bearings generally use steel stamping cages, but for larger sizes that are not easy to be stamped and formed or used for high-speed rotation, turning forming cages are used. Such bearings usually have a dust cover, a seal ring, a non-contact rubber cover, a contact rubber cover or a stop ring bearing.
