Thanks to its special design, this bearing lasts significantly longer than many other ball bearings on the market. The balls run through a specially deepened groove. This makes the ball bearing less susceptible to lateral loads. The groove contains very small channels through which the oil can flow much more easily. This means better lubrication and less friction. The shields fit smoothly and still protect the bearing from dust. The cage keeps the balls perfectly separated, ensuring optimal lubrication. Nitrogen is used during packaging to prevent oxidation in the packaging, so the bearings are fresh until unpacked.
