Product Description

Deep Groove Ball Bearing - 6210 for Machine tool gearboxes, General Machines, Tools
Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are
optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in
both directions, are easy to mount, and require less maintenance than other bearing types.

Q4 - How to customize bearing(non-standard) from your company?

 A -We offer OEM,Customized(Non-standard) service and you need to provide drawing and detailed Technical Data.

Q5 -   What should I care before installation?

 A   - Normally, the preservative with which new bearings are coated before leaving the factory does not need to be

        removed; it is only necessary to wipe off the outside cylin­drical surface and bore, if the grease is not compatible

        with the preservative, it is necessary to wash and carefully dry the bearing.

      -Bearings should be installed in a dry, dust-free room away from metal working or other machines producing

        swarf and dust.

Q6 - How to stock and maintenance my bearings right? 

 A   - Do not store bearings directly on concrete floors, where water can condense and collect on the bearing;

      -Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity

       or sudden and severe temperature changes that may result in condensation forming;

      -Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.
