For bearing mounting and dismounting applications, the required oil pressure is typically less than 100 MPa (14 500psi) and SKF hydraulic pumps can usually be used. However for applications such as couplings, gear and railway wheels, pressures of 300 MPa (43 500 psi) are more typical and SKF oil injectors are preferred.
