Angular Contact Ball Bearings Nsk Global The actual question (almost) the "standard" machined 800mm length 1605 ballscrew is mounted at the motor end using a modified bk12 ballscrew mount block (corners cut and filed to fit in the channel) with the standard 6001zz bearings replaced by 7001dbf angular contact bearings. the question is about how best to mount the far end of the ballscrew. There should be at least 2 ac bearings "back to back" on the motor pulley end. and, a journal bearing at the other end pulling the ballscrew and stretching it by approx o.1mm (0.004"). the pull should be fixed using a ground spacer adjusted to do the job. the bearings should be at least p4 quality. Power off and lock out the machine. remove the necessary covers to access the axis with the problem. remove the axis motor cover. install the coupler installation tool [1] on the motor coupling. turn the ballscrew so you can see the screw [4] for the motor coupling clamp. remove the motor screws [2]. Could be has simple as change of bearings to pair of angular contact if they fit in same space but could also mean completely different approach and need some bearing blocks making or buying.? 02 08 2013 #4.
