Design Philosophy and Key Features

The CR Series motors are constructed with durability, compactness, and noise reduction as core principles. The CR-07-2P0-30-JA-J incorporates several advanced design elements that distinguish it from traditional hydraulic motors:

Cycloid Planetary Gear Mechanism: By utilizing a cycloid curve design, this motor achieves superior power transmission efficiency while maintaining a lightweight and compact structure. This design minimizes internal friction, reduces wear, and extends service life.

Robust Construction: The motor's housing and internal components are engineered to withstand high-pressure environments, shock loads, and cyclic stresses. Its simple yet rigid architecture ensures minimal maintenance requirements and reliable performance in harsh conditions.

Low Noise Operation: Precision-machined gears and optimized fluid pathways significantly reduce operational noise, making it suitable for noise-sensitive environments such as indoor industrial facilities, fishing vessels, and urban construction sites.

High Torque at Low Speeds: As an LSHT motor, it generates substantial torque directly at low rotational speeds, eliminating the need for additional gearboxes and simplifying system design.

Technical Specifications and Performance Data

The table below summarizes the core technical specifications of the CR-07 base model, which serves as the foundation for the CR-07-2P0-30-JA-J variant. The suffix "2P0-30-JA-J" denotes specific configurations for ports, shaft, mounting, and sealing, ensuring compatibility with diverse hydraulic systems.

Displacement and Pressure: With a 106 cc/rev displacement, the motor delivers high torque output per revolution, making it ideal for heavy-load applications. Its ability to operate at 21 MPa rated pressure and 28 MPa maximum pressure ensures reliability under peak loads.

Speed and Efficiency: The motor achieves optimal performance at 465 rpm, aligning with LSHT requirements for direct drive systems. Its efficient fluid dynamics reduce energy losses and heat generation.

Model Suffix Interpretation: The suffix "2P0" likely refers to port size and type, "30" to shaft specifications, and "JA-J" to sealing materials or special adaptations for corrosive environments.

Industrial Applications and Use Cases

The CR-07-2P0-30-JA-J is designed for versatility and is widely deployed in:

Construction Machinery: Powers track drives in excavators, winches in cranes, and mixing drums in concrete trucks, where high torque and ruggedness are critical.
