ML71905CVUJ74S - SNR


High precision angular contact ball bearing, high speed series ML, laminated resin cage centred on outer ring

In the ball bearing and high precision bearing ranges, the high precision angular contact ball bearing solves the maximum reliability constraints with increased performance in terms of rigidity, speed, capacity and precision. This bearing is recommended for demanding applications in terms of precision such as machine tool spindles. NTN-SNR is getting under ranges dedicated to requirements of speed, sealing, specific greasing, etc.
