Radial piston motor manufacturers include:

ITALGROUP

The team at Italgroup SRL have been producing radial piston hydraulic motors since 1985 with yearly production and worldwide distribution now exceeding more than 13,000 units.

Italgroup's hydraulic motor range varies from 20cc to 8500cc displacement, and units can be directly interchanged with Staffa hydraulic motors (Kawasaki Precison Machinery), Riva Calzoni hydraulic motors and Sai hydraulic motors. In addition, two-speed motors and specialised motors can be created to suit clients' applications including sub-sea applications, high and low (2 speed) and wheel motors. Italgroup hydraulic motors can also be asembled together with valves, brakes or gear reduction units. Click here for more information on Italgroup radial piston motors

SAI

 

SAI radial piston motors are available in an extensive range of displacements from 40 cc/rev through to 1200 cc/rev and in nine basic frame sizes. Options include variations on shafts, flanges, bearings, distributors, high pressure shaft seals, and competitor interchangeability.

The SAI Motor is of the eccentric crankshaft design with many exclusive features including:

  • Swivelling Cylinder - This enables the cylinder to remain aligned with the eccentric of the crank, thus eliminating any side loading between the piston and cylinder.
  • Double Piston Support Bearing - The pistons transmit their load to to the shaft via a hydrostatic bearing which reduces metal to metal contact, and a central roller bearing which minimises the sliding velocity between piston and the spherical support ring.
  • Piston Retaining Rings - These ensure that the piston remains in contact with the shaft under all operating conditions, including in cavitation.
  • Axial Flow Rotary Distributor - This ensures that the oil is distributed to the pistons with high efficiency due to short, large section oil paths. Many different distributor options can be fitted to any of the range of motors.
  • GM Series (fixed displacement), GS Series (high speed-high power), BD & GD series (dual displacement)

Other brands of radial piston motor include:

  • Calzoni (Parker Calzoni) radial piston motors; MRD and MRDE series radial piston motors with dual displacement and MRV and MRVE series radial piston motors with variable displacement

  • Denison (Parker Denison) radial piston motors; MR Type, MRD-MRV Type and MRT type

  • Dusterloh KM11 - KM110 type series (with polygon ring and gap ring control), RM80N - RM250N type series (with polygon ring and clearance adjusting control, RM250X - RM900X type series (in piston/connecting-rod-design), RM1000X - RM5000X type series in piston/connecting-rod-design
