Aftermarket Replacement Vane Motors

Vane motors are fixed-displacement hydraulic motors: a rotor with sliding vanes runs inside a cam ring, which makes them reversible, tolerant of stall under load and smooth at speed. They drive fans, conveyors, augers, winches and steering systems on mobile and industrial machines. We supply them as new aftermarket replacements across three series — the M3 · M4 · M5 motors, the 25M · 35M · 45M · 50M motors (standard and heavy-duty bearing versions 26M / 36M / 46M / 51M), and the MV037 high-torque motors. Further series are added as they are released. If yours is not among them, send us the nameplate code and we will match it. All units are quality checked before shipping.

M3 · M4 · M5 SeriesM3 · M4 · M5 SeriesM3 · M4 · M5 replacement vane motors — M3B (8.0 kg, 9.2-37.1 cm³/rev), M4C / M4D / M4E (15.4 / 27.0 / 45.0 kg, 24.4-222.0 cm³/rev) and M5B / M5BS (18.5 kg, 12.0-45.0 cm³/rev, up to 290 / 320 bar). All units are new aftermarket replacements, quality checked before shipping.MV037 Vane MotorsMV037 Vane MotorsHigh-torque vane motors, MV037 series — single-rotor 197-606 cm³/rev (12-37 in³); the two-port double stack (1,049-1,213 cm³/rev) and four-port (393-1,213 cm³/rev) versions carry two rotating groups. Rated Code 61 (207 bar continuous) and Code 62 (310 bar continuous), up to 1,000 rpm, with a ten-item ordering code. All units are new aftermarket replacements, quality checked before shipping.25M · 35M · 45M · 50M Series25M · 35M · 45M · 50M SeriesThe 25M / 35M / 45M / 50M frames - twelve nominal torque ratings from 42 to 300 lb·in per 100 psi, 43.9 to 317.1 cm³/r; each also available as a heavy-duty bearing version (26M / 36M / 46M / 51M).

Selection notes

Match three things first: the displacement (cm³/r) or torque rating the machine needs, the mounting flange and port connections, and the shaft. Vane motors are reversible — rotation is set by the direction of flow — and they can be stalled under load without damage when the circuit is protected by a relief valve. Continuous and intermittent ratings differ, so tell us the duty cycle; case drain lines must stay unrestricted. Ratings are per series, so confirm them against the full model code or the nameplate.

Ordering

Send the complete model code from the nameplate — series, displacement or torque rating, mounting and port connections, shaft, port position and any suffix. Every maker uses its own code system and they are not interchangeable, so we identify the series first and confirm the fit before you order.
