The Design of Rolling Bearing Mountings Part 2 docx

... pres- sure in the rolling contact area of the bearing is rela- tively low (p 0 ≤ 2, 000 N/mm 2 ), and the bearings are failsafe. Consequently, the service life of the bearings is dictated by the grease ... sealing The bearings are greased for life with the FAG rolling bearing grease Arcanol L74V. Approximately 35% of the spindle bearing cavity and approxim...
