Review on 6203 2RS 17X40X12Mm Double Bearings Pre Lubricated by Daniel Alires

The bearings are of poor quality .As a result of using this product, I found that they have a tendency to break apart and fail prematurely. This is a huge concern as it can cause damage to industrial and scientific equipment. The pre-lubrication does not last long either, leading to additional maintenance and replacement costs. The only advantage is that they are relatively inexpensive. However, I would not recommend them for any important application..
