Hydraulic cylinder wheel bearings

Hello forum, I need mla your help: Who can tell me where I get a tool for pressing wheel bearings on the vehicle. I have a mounting kit wheel bearings from BGS and want to do the whole hydraulically by hand pump. Unfortunately, I don’t know what I need here for a tool / hydraulic cylinder. Can anyone help me here? (P.S. Payable should all this also be) Thanks Thomas
