Hydraulic Motor Torque Calculator
Calculate theoretical hydraulic motor torque from pressure and motor displacement.
Enter Details
GuideTorque (Nm) = Pressure (bar) × Displacement (cc/rev) ÷ 62.83
Actual torque is adjusted by mechanical efficiency.
Use 100% efficiency for theoretical torque. Use lower values to estimate real-world output torque.

Actual Motor Torque— Nm— lb-ft
Theoretical @ 100%— Nm
Efficiency Used— %
Important NoteActual torque depends on motor design, pressure drop, leakage, speed, temperature, case drain and manufacturer specifications.
