1 Product Overview
General
Double row angular contact ball bearings provide the function of a pair of single row angular contact ball bearings, arranged back-to-back, but requiring less space.
Double row angular contact bearings provide very stiff, rigid bearing arrangements. They are also able to accommodate combined loads and are very suitable in supporting tilting moments.
Misalignment
Double row angular contact ball bearings must not be exposed to any misalignment.
Minimum Load
Bearings require a minimum load under all operating conditions to ensure kinematically correct rolling element function.
For double row angular contact ball bearings the minimum load must be 1% of the dynamic load rating.
