SNR - MLECH7020CV

Details

MACHLINE is the SNR range of high precision bearings. It combines high speed and increased load capacity to meet the ever increasing demands of your machines. The sealed MLE range has lifetime lubrication, eliminating the need for periodic lubrication. The CH ceramic ball bearing versions increase speed (+30%) and rigidity (+10%) compared to the standard versions. In a spindle, when it is not necessary to install an oil lubrication circuit and when grease lubrication is sufficient, SNR offers a technically adapted and economically advantageous solution. In this case, we recommend the use of bearings from the MLE family, consisting of the 71900 and 7000 series. 4S manufacturing accuracy as standard, Nitrile seals fixed to the outer ring, which allows the same limiting speed to bemaintained as in an open bearing. Variants depending on contact angle (C for 17º and H for 25º) and preload. Available for all ML, MLE and 7000, 71900 and 7200 series, with silicon nitride balls and steel bushings, combining the best properties of both materials: Reduced thermal level and increased limiting speed. Reduced lubrication requirements compared to an «all steel» bearing. Significantly increased rigidity and service life.
