For procurement teams tasked with sourcing components that offer both power and operational flexibility, this motor represents a superior solution. It builds upon the robust foundation of the CR-Series with the added benefit of a dual-displacement design, making it a versatile choice for complex machinery. This guide will decode its model number, present its full technical specifications, and elucidate the unique advantages it brings to demanding mobile and industrial equipment.

Model Number Breakdown: Understanding CR-04-2S0-30-D-JA-J

Accurate component identification is the first step in the procurement process. The model number CR-04-2S0-30-D-JA-J reveals critical information about the motor's design and capabilities:

• CR: The series designation for TOKYO KEIKI's Gerotor (Orbit) type hydraulic motors, known for high torque and smooth low-speed operation.

• 04: The frame size, indicating a compact physical housing consistent with other models in the CR-04 series for easy integration.

• 2S0: This is a crucial differentiator. It signifies a dual-displacement motor. The "S" indicates a switching function, allowing the motor to operate at two different displacement settings—in this case, a high-displacement and a low-displacement mode.

• 30: Defines the output shaft and flange type, specifying a keyed shaft and a standardized SAE 2-bolt mounting flange.

• D: This suffix often denotes a specific port configuration or a design revision. In this context, it typically means the hydraulic ports are positioned on the side of the motor, which can be critical for plumbing and installation space.

• JA: A key feature indicating keyed internal components. This robust design locks the internal gerotor set to the shaft, preventing slippage under high shock loads and ensuring long-term durability.

• J: Specifies the use of JIS (Japanese Industrial Standards) taper threads for hydraulic ports, a critical detail for ensuring leak-free connections with the correct fittings.

This detailed nomenclature highlights that the CR-04-2S0-30-D-JA-J is not a standard single-displacement motor but a more advanced, versatile unit.

Distinctive Features and Operational Benefits for Procurement

The CR-04-2S0-30-D-JA-J offers a unique set of advantages that differentiate it from standard hydraulic motors and provide significant value in machine design and operation.

1. Dual-Speed and Dual-Torque Capability (2S0 Code): This is the motor's most significant feature. It can be switched between a high-displacement mode (for high torque at low speed) and a low-displacement mode (for higher speed with lower torque). This allows a single machine to perform both high-power, slow-moving tasks and low-power, fast-moving tasks without requiring a complex transmission or oversized components.

2. Robust Keyed Internal Construction (JA): Consistent with the quality of the CR-Series, the JA designation ensures the internal gerotor assembly is keyed to the shaft. This is a critical durability feature for a motor designed to handle varying loads, as it provides a positive drive connection that resists wear and failure under strenuous conditions.

3. Side Port Configuration for Flexible Installation (D-code): The side-mounted hydraulic ports offer distinct advantages in machinery with limited axial space. This configuration can simplify hose routing, reduce potential for hose abrasion against the frame, and enable a more compact overall system design.

4. Enhanced System Efficiency and Versatility: By allowing the machine to operate in an efficient high-speed mode when full torque is not needed, this motor can contribute to overall system energy savings. It effectively provides two motors in one, simplifying inventory for OEMs and offering end-users greater operational flexibility from their equipment.

5. Proven Gerotor Performance: It inherits all the inherent benefits of the gerotor design, including excellent starting torque, very smooth rotation at ultra-low speeds, and high tolerance to hydraulic system contamination, leading to extended service life.

Ideal Applications and Industry Use Cases

Procurement specialists will find demand for this specific motor in applications where operational flexibility is critical. Key industries and uses include:

• Construction Equipment: Drive systems for mini-excavators and compact loaders, where high torque is needed for digging/loading and higher speed for quick travel between sites.

• Agricultural Machinery: Feed mixer wagons, conveyor drives, and fertilizer spreaders that require different speeds for filling, mixing, and spreading operations.

• Material Handling: Drive units for pallet trucks that need high torque for lifting and ramp climbing but higher speed for long, flat warehouse travel.

• Specialized Vehicles: Aerial work platforms and other utility vehicles that benefit from a "high" and "low" range for drive wheels.

Conclusion: A Strategic Component for Advanced Hydraulic Systems

The TOKYO KEIKI Hydraulic Motor model CR-04-2S0-30-D-JA-J is more than a power source; it is an integrated efficiency and versatility solution. Its dual-displacement capability, combined with the proven durability of the JA construction and the practical side-port design, makes it a strategically advantageous component for procurement. By specifying this model, you enable the design of more capable and efficient machinery, ultimately providing greater value to the end-user.
