Performance details

Bearing Vibration

Measuring vibration is an effective method of ascertaining how well a bearing is manufactured. High-frequency vibration levels, often called spike energy, detect minute microscopic flaws in rolling element bearings. The results below show a typical wheel bearing after 4000km of use. Lower values indicate a superior life and reduced losses from friction losses.

Genuine Bearings, Counterfeits and B Grade

This is a 100% Genuine NTN Bearing. It has been sourced directly from NTN Europe in Annecy, France. It is not B graded, counterfeit or an NTN labelled product from a third party. You can read more about this in the article Counterfeit NTN and SKF Bearings

There have been widespread reports of counterfeit and substandard (B Grade) bearings being sold to unsuspecting customers in the media. Using these items often results in diminished performance, reduced life and sometimes injury to personnel.

Genuine NTN vs Other NTN

The pictures below show two NTN Bearings, the bearing on the left is from Hambini via NTN in France, and the one on the right was purchased from a well-known UK bicycle bearing distributor; they claimed to have sourced their bearings from NTN. From the outside, they both look to be identical, and the packaging that they came in appeared to be identical. Further inspection of the bearings revealed largely similar seals that would be indiscernible to the average consumer. However, upon disassembly, several discrepancies were noted; the most obvious was the 40% higher ball count on the Hambini supplied bearing. Additionally, the Hambini supplied NTN bearing had a riveted metal cage, the distributor's bearing was folded sheet metal. Folded metal cages have considerably poorer load and stiffness ratings. The distributor bearing had failed after only 600km, a root cause investigation was conducted, and the bearings were found to be of dubious quality with an unverifiable supply chain.

    Transformed my HED Wheels from quality to amazing. Make no mistake these are some of the best bearings on the market. Just be sure you know your bearing size. I thought the front hub was 6902 but was mistaken they are smaller 6900.
