A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permitsangular misalignment. Typically these bearings support a rotating shaft in the [bore] of the inner ring thatmay be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internalshape of the outer ring and spherical rollers.Despite what their name may imply,Spherical roller bearings are not truly spherical in shape. The rollingelements of spherical roller bearings are mainly cylindrical in shape,But have a profile that makes themappear like cylinders that have been slightlyover-inflated. Spherical roller bearing used in countlessindustrial applications, where there are heavy loads, moderate speeds and possibly misalignment.

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.
