Bogus Bearings Look More Real Than the Real On
Bogus Bearings Look More Real Than the Real Ones A recent onslaught of bogus after-market bearings in China has created a major headache for legitimate bearing makers like SKF and Timken , who say that it's often very difficult to distinguish the fakes from the non-fakes.
Where are your bearings coming from? - skf.c
real SKF bearing – but your machine will! Fig. 1 Fig. 2 Fig. 3 Fig. 1. Fresh out of “production line” the Fig. 4 counterfeit bearings looks good on the surface. Fig. 2 and 3.

Axial (thrust) bearings support loads parallel to the axis of the shaft, such as those exerted by a table supporting a weight. Radial bearings support rotating wheels and other applications where the force of the load is perpendicular to the shaft. Ball bearings are used with applications that have high axial loads and low-to-moderate radial loads.
