* Intermittent operation: the permissible values may occur for max. 10% of every minute.
** Peak load: the permissible values may occur for max. 1% of every minute.
*** For speeds lower than given, consult factory or your regional manager.

1. Intermittent speed and intermittent pressure must not occur simultaneously.

2. Recommended filtration is per ISO cleanliness code 20/16. A nominal f iltration of 25 micron or better.
3. Recommend using a premium quality, anti-wear type mineral based hydraulic oil HLP(DIN51524) or HM ( ISO 6743/4).
If using synthetic fluids consult the factory for alternative seal materials.
4. Recommended minimum oil viscosity 13 mm²/s [70 SUS] at 50°C [122°F].
5. Recommended maximum system operating temperature is 82°C [180°F].
6. To assure optimum motor life fill with fluid prior to loading and run at moderate load and speed for 10-15 minutes.

Hydraulic motors type MR...T with tacho connection

MR motors are available in version with tacho drive shaft. With tacho connection the
speed of the motor can be registered. Tacho shaft has a 6 times higher revolution
speed than output shaft and opposite direction of rotation.

Notes:
Radial or axial load on tacho shaft must be avoided. Max. torque on tacho shaft 0,1 daNm [.885 lb-in].
Max. cont. return pressure without drain line 20 bar [290 PSI].
Tacho option for MR motor is available only for shafts with sealing diameter ø28,56 with shaft seal
type D (up to 150 bar).
It is not allowed for Q-flange.

The main technical features correspond to the standard motors series MR. There are no changes in
the overall and mounting dimensions. For detail technical and mounting data please refer to MR
catalogue.
