IBC WALZLAGER GMBH - HM 71911.E.T.2RSZ.P4A.UL

Details

UL = Universal, Light Preload. P4A = Bearing With Extreme High Running Accuracy (Abec9) And Form Tolerance (Abec7), T = Cage Of Machined Phenolic Resin, Located On Rolling Elements. The HM design combines the advantages of the other two versions. It achieves almost as high speeds as the H version and at the same time has load ratings that are only slightly below the standard version. The high speed increase is made possible by an optimized internal design. In addition to the slightly reduced rolling element diameter compared to the standard design, the HM design has a more open raceway curvature, which ensures less friction and thus lower heat generation in the rolling bearing. The high precision of the components, especially the raceways, also reduces the running noise in the operating condition. The optional sealing on one or both sides with non-abrasive sealing washers (2RSZ), which do not restrict the suitability for high speeds, give the sealed high precision angular contact ball bearings the ideal protection against contamination and air flows.
