Lead In Chamfer for spherical bearing?

Lead In Chamfer for spherical bearing?

(OP)
I have a question and since i do not have access to a handbook i guess i will start here. I have a spherical bearing MS14101-3P in which will be installed in .218 thk alum arm. one person at work is telling me the lead in chamfer should be .040-.045 x 45 deg. and the other person is telling me it should be .020-.025 x 45 deg. when i use the first chamfer on both sides of the arm it looks like there is alot less radial material for the bearing to hold. I think it should be .020-.025 x 45 deg. can someone help me with this. sorry but im a new designer.

RE: Lead In Chamfer for spherical bearing?

When I install or assemble things, whether with interference or clearance I prefer a shallow angle. More like 15 degrees. And, the corner where the lead meats the cylindrical bore needs to be deburred, smoothed, and even polished to an organic profile. A machined chamfer can have a sharp edge that is an effective cutting tool, skiving a series of golden whiskers off the OD of a bronze bushing. With careful deburring of the steel housing and a little lubrication or even Loctite the same bushing can be pressed into hole with 0.003 inch interference or more with the OD perfectly intact.
