Observing with the naked eye, you can recognize genuine NSK bearings with laser markings, so the engraving is very clear and deep, although the font size is very small.

2. Check that the product name and code are correct with the manufacturer’s production batch

You can check on the container and just like scanning barcodes with packaged products, you can completely read the production lot number against the item code.

3. About the packing specification

For famous products with global brands, the manufacturer is very important in product packaging, providing full documents proving the origin (CO, CQ). As for fake products, the product packaging will be of lower quality to reduce costs and not have enough CO and CQ.

4. Deviation

The misalignment of genuine NSK bearings is very low, if any, the deviation is very low, no more than 1 micrometer, and does not cause abnormal noise when rotating. Meanwhile, if you have experience in evaluating bearings, you will notice that counterfeits will have a certain deviation and in some cases, you can see them.
