SG02

Toshiba SG02 hydraulic motor characteristics

The Toshiba SG02 hydraulic motor is an axial piston motor designed to drive the slewing mechanism (swing motor) in construction equipment, particularly in small and medium-sized excavators. It is part of a single unit that includes the high-speed hydraulic motor itself and a planetary gearbox that reduces the rotation speed and increases the torque on the output shaft. Such units ensure smooth and precise rotation of the excavator platform.

Technical specifications of the Toshiba SG02 hydraulic motor:

• Type: Hydraulic motor-reducer for platform rotation
• Construction: It is an assembly of two main parts:
  • Hydraulic motor: An axial piston motor with a swash plate or swash plate that converts the energy of the hydraulic fluid flow into the rotational motion of a shaft.
  • Gearbox: Multi-stage planetary gearbox that reduces speed and significantly increases torque.
• Working pressure: Approximately 170-210 bar (17-21 MPa)
• Platform rotation speed: 10-14 rpm. The rotation speed of the shaft of the hydraulic motor itself is much higher and depends on the gear ratio of the gearbox.
• Weight: approximately 35-50 kg
• Application: Used as the main tower rotation motor on crawler excavators weighing from 6 to 12 tons.
