Introduction:
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other
in the direction of the bearing axis. This means that these bearings are designed to accommodate combined
loads, i.e. simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The
contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways
in the radial plane, along which the combined load is transmitted from one raceway to another, and a line
perpendicular to the bearing axis.
The most commonly used designs are:
A. Single row angular contact ball bearings.
B. Double row angular contact ball bearings.
C. Four-point contact ball bearings.

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.
