26M65A 1C20

The 26M65A 1C20 motor belongs to the Vane Motors series from Vickers and serves hydraulic automation systems by converting pressurized fluid into controlled rotary motion. A balanced cartridge design keeps internal forces symmetric, reducing shaft side load and prolonging seal life. Heavy-duty bearings carry elevated radial and thrust loads encountered in high-pressure circuits. The bidirectional rotation capability lets the same unit drive or brake in either direction without reconfiguration. Ten vanes distribute load evenly around the rotor, which minimizes torque ripple for smoother machine movement. A ring torque rating of 65 in-lb per 100 psi quantifies the rotor ring’s ability to transmit force under system pressure. Design number 20 identifies the internal geometry used for this performance level, and four selectable cover positions let installers align the housing to fit confined mounting envelopes.

An external case drain located on the cover lets excess leakage escape, preventing pressure buildup that could damage the shaft seal. The SAE 2-bolt mounting flange provides a common footprint for quick substitution into existing manifolds, while SAE 4-bolt flange port connections withstand high working pressures and simplify rigid piping. Fluid entry and exit are arranged through ports on both the body and the cover, and the port location is kept inline with the body port to streamline hose routing. When assembled, this configuration keeps flow paths short, reducing energy loss and heat generation. These interface details complement the cartridge design by making the motor adaptable to varied installation requirements without altering core hydraulic performance.
