About Hydraulic Motor

[umairnazar]

hello dear
I have to install a hydrauic motor over a support coulumn Jack.The support column jack is a screw jack. Now we have to install/couple a hydraulic motor over it in order to rotate the sxrew jack so that the jack moves up and down
Which motor will be most suitable (operationally and economically) for my application. Tell me any model from Bosch Rexroth. the support column will not be operated frequently. they will only be used in order to lift the Crane Chassis.

Specifications:
RPM : 0 to 50
Torque: 1800 Nm
Pump Flow: 35 lpm
System Pressure: 210 bar
Waitig for your kind reply
Regards.

You have all your specs, and brand preference, I would call up your local Bosch Rexroth dealer. The problem will be finding something that runds smooth at low end RPM.

hello dear;
thanks for the reply
Why have u chosen a Radial motor, why not a fixed axial bent motor?? Can't we get the required Torque (Nm) from the pressure and flow our system.

[Doug Hanson]

I suggested the radial piston motor, because the speed you specified was 0 - 50 rpm, which rules out an axial piston motor, they don't like running that slow, and the displacement required would make an axial piston motor very expensive. For torques and speeds as spec'd you should look at a a "Low Speed High Torque Motor"

Sir thanks a lot for your guidance and i will bothering you in future as well, I hope you dont mind;
Regards and Thanks once again
