Nachi PCR Series

Nachi PCR series hydraulic motors are popular axial piston hydraulic motors (swing motors) primarily used for swing and rotary drives in construction equipment.

Main Characteristics of NACHI PCR Series

Type

Axial piston hydraulic motors with integrated planetary gear for swing drives (swing motors).

Purpose

Rotation of tower/platform of heavy equipment (excavators, etc.) with high precision and reliability.

Compact Design

Efficient component layout ensures reduced dimensions and allows installation under the operator's seat or in confined spaces.

No Need for Transmission Oil Changes

The gearbox/transmission is lubricated by the working hydraulic oil, which simplifies maintenance.

Built-in Holding System

Some models feature an integrated holding system that prevents unintended rotation of the mechanism when the machine is stopped.

Smooth Switching

Standardized motor equipment provides shockless relief, which softens sharp hydraulic shocks during start/stop movement.

Main Advantages of Nachi PCR Series Hydraulic Motors

• Compact and efficient design — allows motor integration in narrow spaces and reduces external equipment dimensions.
• Minimal maintenance — no need to service separate transmission-gearbox oil.
• Enhanced reliability — Japanese quality of construction and materials ensures long service life.
• Operational safety — built-in parking brakes and smooth shock load reduction system.
• Application flexibility — the series includes models with different load parameters and torque, allowing selection of solutions for specific machines.
• Standard characteristics for heavy equipment — designed for working pressures and loads typical of professional heavy machinery (data for specific models depends on application).

Applications of Nachi PCR Series Hydraulic Motors

• Rotation of tower platforms (swing) in excavators, cranes, manipulators.
• Systems requiring high positioning accuracy and smooth braking.
• Harsh operating conditions — low temperatures, high loads, frequent start/stop cycles.
