A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits
angular misalignment. Typically these bearings support a rotating shaft in the [bore] of the inner ring that
may be misaligned in respect to the outer ring.   The misalignment is possible due to the spherical internal
shape of the outer ring and spherical rollers.

Despite what their name may imply,Spherical roller bearings are not truly spherical in shape. The rolling
elements of spherical roller bearings are mainly cylindrical in shape,But have a profile that makes them
appear like cylinders that have been slightlyover-inflated. Spherical roller bearing used in countless
industrial 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.
