If you have a O.0025 in clearance between the shaft and 6203 bearing race. The shaft will spin at 750 rpm, the bearing is a press fit into a housing. What Loctite would be suitable to tighten up the shaft to race fit? Also, how difficult will be the removal of the Loctite at the next bearing replacement? Thanks

638 , removal by conventional methods like puller or by heating above working temp 250 degrees

@@johngamal141 Thanks so much for your response.....I read up on 638 and that's what I was hoping for. Ordered me a bottle. One more little question, without using activator or primer, about how much time before it's set? The inner race does not shoulder up on the shaft, so there is some adjustment that may be needed once the bearing has found home.

@@joad47 you are welcome, usually 638 does not need activator, but you should prepare the surface well regarding roughness use a very fine sand paper in squirel motion to take the most of the strength of loctite The initial curing time is 15 min and takes full strength in 24 hours and may give it a little bit more in cold temperatures like 2 days.
