BEARING NTN-SNR MLE 7008HVUJ84S F65 K 008 IRT

BEARING NTN-SNR MLE 7008HVUJ84S F65  K 008 IRT

High-precision angular contact ball bearing, ML series sealed, laminated phenolic resin cage, outer ring centred

High-precision radial ball bearings increase machine reliability through optimised rigidity, speed, load carrying capacity and precision. They are ideal for applications where precision is particularly important, such as machine tool spindles. In addition to the standard range, there is a range of bearings to meet specific requirements for speed, seals, lubrication features, etc.
