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.

    There is something about these bearings that make then stand out from others I have bought from different outlets in the past! This might sound strange but there is a feel of exceptional quality. I contacted Hambini for advice on a Friday evening using the online contact form and 22 mins later I had a full and very informative reply. Placed the order and shortly after recieved a message saying that my order was processed and on it’s way! The service I recieved from Hambini is nothing short of exceptional and from now on I will be purchasing my bearings from Hambini and I’d recommend that you, the reader of this review does so also! Check out his YT videos also! Entertaining and very informative 🙂 You are rare find Hambini – Thank you!
