1. Introduction to TOKYO KEIKI and the CR-Series

TOKYO KEIKI INC. has established a global reputation for manufacturing high-precision instruments and hydraulic components since its founding in 1896. Their commitment to quality, innovation, and reliability is embodied in every product, including the esteemed CR-Series of gerotor-type hydraulic motors.

The CR-Series is specifically designed as a compact, high-torque motor. The gerotor principle—using an internal gear (gerotor) set—is renowned for its high starting torque, smooth rotation at very low speeds, and exceptional durability. The model CR-04-2P0-30-JA-J is a specific configuration within this series, optimized for a wide range of industrial and mobile machinery.

2. Detailed Model Analysis: Decoding CR-04-2P0-30-JA-J

Understanding the model number is key to recognizing its capabilities. Let's break it down:

• CR: Denotes the series, which is the Gerotor (or Orbit) type hydraulic motor.

• 04: Indicates the frame size or the physical dimension series of the motor housing.

• 2P0: Specifies the displacement. In this case, it is 20 cm³/rev (20 cubic centimeters per revolution). This is a critical parameter defining the motor's torque output per unit of pressure.

• 30: Refers to the flange type and shaft specification. This code points to a specific mounting flange (e.g., SAE 2-bolt) and a keyed shaft design, ensuring compatibility with standard industry connections.

• JA: This suffix indicates the inclusion of keyed internal components, specifically the gerotor set and shaft, which are essential for handling high loads and resisting wear.

• J: The final "J" typically signifies a standard Japanese Industrial Standards (JIS) port thread, which is a crucial detail for procurement to ensure proper hydraulic line connectivity.

This detailed nomenclature provides a complete picture of the motor's core physical and performance characteristics before even reviewing the datasheet.

3. Technical Specifications and Performance Data

The following table provides a consolidated view of the primary technical specifications for the CR-04-2P0-30-JA-J. This data is essential for verifying compatibility with your system requirements.

4. Key Features and Operational Benefits for Your Applications

For a procurement professional, understanding the features that translate into operational benefits and long-term value is paramount.

• Exceptional Low-Speed, High-Torque Performance: The gerotor design is inherently superior for LSHT applications. The CR-04-2P0-30-JA-J provides high torque from the moment it starts, ensuring smooth and powerful operation even under substantial load at speeds as low as 1 rpm. This eliminates cogging and jerky motion, which is critical for precision tasks.

• Robust Construction and High Durability: The inclusion of the "JA" suffix signifies keyed internal elements. This design prevents the internal gerotor set from slipping on the shaft under high stress or sudden load changes, a common failure point in inferior designs. This directly translates to a longer service life, reduced downtime, and lower total cost of ownership.

• High Power Density and Compact Design: Despite its robust output, the motor features a very compact and lightweight design (Frame Size 04). This allows for easy integration into space-constrained machinery without compromising on power, enabling more streamlined and efficient equipment design.

• High Pressure Capability: With a maximum operating pressure of 210 bar, this motor is built to handle the rigors of demanding hydraulic systems. This high-pressure rating means it can deliver its rated torque in the most challenging conditions, providing a reliable power source for heavy-duty applications.

• Standardized Mounting and Porting: The specified flange (SAE) and port threads (JIS) are industry standards. This ensures straightforward installation and interchangeability, reducing engineering time and simplifying the procurement of ancillary components like couplings and hoses.

5. Target Industries and Application Examples

The versatility and reliability of the CR-04-2P0-30-JA-J make it an ideal choice for a multitude of sectors. Procurement teams in the following industries will find this motor to be a frequently requested component:

• Construction and Earthmoving: Track drives for mini-excavators, swing drives, auger drives, and conveyor systems.

• Agriculture: Drives for fertilizer spreaders, planter meters, conveyor chains in harvesters, and irrigation systems.

• Material Handling: Wheel drives for pallet trucks, order pickers, and drive mechanisms for conveyor rollers.

• Forestry and Recycling: Feed roller drives in woodchippers, and rotation mechanisms in compactors and balers.

• Industrial Machinery: Mixers, winches, and indexing tables where controlled, powerful rotation is required.

6. Sourcing and Quality Assurance
