Needle Bearing Removal Q's
Yowza... Not a big problem for me as we have a work around... But I sure
could use a better process... So... Some of my multiple spindle heads have small needle bearings installed to support the shafts laterally while they drill vertically... Some of these are as small as .250" ID up to around .400" ID. Most are installed in aluminum and steel blind holes with no way of pushing them out from behind. Anyone know of a tool or method of removing these without damaging the housing (esp. aluminum) that they are mounted in? In some cases, they are double stacked and are of either the same size or two sizes - larger ID and OD unit on top of a smaller one in a blind hole below, etc. When stacked, they have thrust bearings between or a step in the housing if thrust is not an issue. Any ideas, assistance, etc would be greatly appreciated. ...Especially if it is a tool or manual process rather than EDM, etc. Regards, Joe Agro, Jr. (800) 871-5022 (908) 542-0244 Automatic / Pneumatic Drills: http://www.AutoDrill.com Multiple Spindle Drills: http://www.Multi-Drill.com V8013-R |
