SNR - MLCH71917HV

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 ML range has been specially designed to withstand very high speeds. All MACHLINE® spindle bearings are produced to the P4S precision specification, which incorporates ISO 4 dimensional tolerances and ISO 2 dynamic tolerances. Specally designed geometry: reduction in ball diameter, increase in number of balls and optimization of cage guidance on outer ring. Different variations according to contact angle (C for 17° and H for 25°) and preload. The CH ceramic ball bearing versions increase speed (+30%) and rigidity (+10%) compared to the standard versions. 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. increased rigidity and service life.
