How to Distinguish SKF Bearings
If you're looking to identify genuine SKF bearings, there are several key factors you should check. Here's a detailed guide to help you distinguish authentic SKF bearings from counterfeits. 1. **Original Quality Certificate**: Genuine SKF bearings come with an original quality assurance certificate. This document confirms the product’s authenticity and origin. Always ask for it before making a purchase. 2. **Packaging Color and Anti-Counterfeit Label**: The packaging of genuine SKF bearings is typically light green. Additionally, each bearing has a unique anti-counterfeit label with a fixed pattern. If you have the number on the label, you can verify it directly with SKF. 3. **Wooden Packaging**: Original SKF bearings are packed in wooden boxes that must remain unopened. These boxes are fumigated for customs clearance and are sturdy, well-constructed, and free from any signs of damage or deformation. The corners of the box should not be warped or bent. 4. **Inner Rust Protection**: Inside the bearing bag, the rust protection should be colorless and odorless. Counterfeit products often contain impurities that may emit a strong, unpleasant smell. 5. **Paper Packaging and Glue Test**: Bearings packaged in paper can be tested by burning a small part of the package with a lighter. Genuine SKF uses imported glue, which burns differently from domestic glue. The paper should also be easy to open without tearing. 6. **Marking and Lettering**: When opening the package, check the markings on both the inside and outside of the bearing. English letters on genuine SKF bearings have specific meanings. In contrast, counterfeit products may use sulfuric acid to engrave text, which is not standard. 7. **Steel Quality**: SKF bearings are made using high-quality steel produced exclusively by SKF-approved steel mills. This ensures superior durability and performance. Always look for this detail when inspecting the product.
