Reply To: SKF "CONCENTRA" Axle bearings

[brian downing]

Here are the release instructions from the SKF ConCentra PDF (easily found via search engine).

Lightly tap the sleeve edge on the mounting collar side of the bearing until the locking system releases the shaft. As an alternative, tap on the bearing inner ring side face on the side opposite the collar.

I’ve just installed mine and have not yet needed to either re-grease or release/remove, but when I do, I’ll use a plastic hammer or a piece of PVC with a steel hammer to protect the bearings. “Lightly tap” means these should free easily.
