Ronzio motor MW4-**-RE

Ronzio W4 series gear motor, with cast iron body and covers, for heavy duty. It has axial compensation by pressure-balanced bushings and an average volumetric efficiency of 95 to 97%.

In the options, choose the displacement (90, 110 or 130) and, for 90 and 110, the version with SAE C flange. According to the W4 catalogue, the maximum pressures are:

• 90 (88.7 cm³/rev): 250 bar continuous, 280 bar intermittent
• 110 (105.4 cm³/rev): 240 bar continuous, 260 bar intermittent
• 130 (127.5 cm³/rev): 220 bar continuous, 240 bar intermittent

For bidirectional motors, the manufacturer says to reduce these pressures by 15%. Before ordering, check the flange, shaft and ports on the motor nameplate.
