I bought new bearings for the ball screws on my mill, SKF 7204 BECBP. http://www.skf.com/skf/productcatalogue/Forwarder?action=PPP&lang=en&imperial=false&windowName=null&perfid=123002&prodid=1230020204
I have read conflicting information on how to install them. It appears the best way would be installing them back to back, but I have read the inner rings should be clamped tight and also read the outer rings should be clamped tight when there back to back. I am not sure I understand the proload either and can't decipher what it is form the SKF website. This is what I think I need to do, find what the preload is (weight) and measure the defection of the outer race when this weight is placed on the bearing. Take this measurement X 2 and shim between the the races of the two bearings and clamp tight the inner rings and I will have the correct preload. Do I have this right. How do I find the preload Your help is greatly appreciated, Bruce ------------------------------------------------------------------------------ RSA® Conference 2012 Save $700 by Nov 18 Register now! http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
