When we opened the box we were surprised to see that someone else had already taken it apart for us. It was completely dismantled. The first thing we had to do was sort through the box to ensure that none of the critical components were missing. After this we turned our attention to the reason the spindle failed. The #1 bearing was destroyed! Evidence suggested that cutting fluid and particulate had migrated into the front bearing over time and eventually resulted in its failure. The shafts taper was also dented and well worn! We were able to repair this shaft surface with a Kiss grind. Of course we also replaced all of the bearings and seals with new. We offered to rebuild the drawbar assembly but the customer respectfully declined because they were confident the Belleville\u2019s and Gripper still had some life in them.<\/p>\n<div id=\"attachment_6471\" class=\"wp-caption alignleft\" style=\"width: 365px;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6471\" src=\"\/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_lube-washed-out-from-bearings.jpg\" sizes=\"(max-width: 355px) 100vw, 355px\" srcset=\"\/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_lube-washed-out-from-bearings-89x75.jpg 89w, \/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_lube-washed-out-from-bearings-178x150.jpg 178w, \/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_lube-washed-out-from-bearings-200x169.jpg 200w, \/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_lube-washed-out-from-bearings.jpg 355w\" alt=\"Mitsui Seiki Spindle Repair and Rebuild_lube washed out from bearings\" width=\"355\" height=\"300\" aria-describedby=\"caption-attachment-6471\" \/><\/p>\n<p id=\"caption-attachment-6471\" class=\"wp-caption-text\">Lube washed out and degraded.<\/p>\n<\/div>\n<div id=\"attachment_6472\" class=\"wp-caption alignright\" style=\"width: 365px;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6472\" src=\"\/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_shaft-ID-needing-kiss-ground.jpg\" sizes=\"(max-width: 355px) 100vw, 355px\" srcset=\"\/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_shaft-ID-needing-kiss-ground-89x75.jpg 89w, \/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_shaft-ID-needing-kiss-ground-178x150.jpg 178w, \/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_shaft-ID-needing-kiss-ground-200x169.jpg 200w, \/wp-content\/uploads\/2018\/02\/Mitsui-Seiki-Spindle-Repair-and-Rebuild_shaft-ID-needing-kiss-ground.jpg 355w\" alt=\"Mitsui Seiki Spindle Repair and Rebuild_shaft ID needing kiss ground\" width=\"355\" height=\"300\" aria-describedby=\"caption-attachment-6472\" \/><\/p>\n<p id=\"caption-attachment-6472\" class=\"wp-caption-text\">The shaft taper ID will need a kiss grind.<\/p>\n<\/div>\n<p>Once this Mitsui Seiki spindle was assembled we ran it up on our test bench for 8 hours.
