Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways.
This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings
according to the number of rows of rollers installed.
Single row tapered roller bearings can withstand radial loads and axial loads in a single direction.
When the bearing is subjected to a radial load, an axial component will be generated, so that another bearing that can withstand
the axial force in the opposite direction is needed to balance.

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.
