Introduction to the TOKYO KEIKI CR-Series Gerotor Motor

For procurement specialists sourcing reliable and efficient hydraulic drive components, the choice of motor directly impacts equipment performance, operational uptime, and total cost of ownership. This product introduction provides a detailed examination of the TOKYO KEIKI Hydraulic Motor, model CR-04-2P4-30-JA-J, a standout unit in the renowned CR-Series of gerotor motors. Renowned for their exceptional low-speed, high-torque (LSHT) characteristics, these motors are engineered for demanding applications where compact power, smooth operation, and unwavering durability are non-negotiable. This document will dissect the motor's technical specifications, decode its model number for precise identification, and highlight its key advantages to empower your component selection process.

Decoding the Model: CR-04-2P4-30-JA-J

A critical skill in procurement is understanding manufacturer nomenclature to ensure exact component matching. The model number CR-04-2P4-30-JA-J provides a complete blueprint of the motor's identity:

• CR: Identifies the product series, in this case, the Gerotor (Orbit) type hydraulic motor.

• 04: Specifies the frame size, indicating the motor's physical dimensions and housing configuration.

• 2P4: Denotes the displacement. This code corresponds to a 25 cm³/rev (cubic centimeters per revolution) capacity. This is a higher displacement compared to the 20 cm³/rev model, directly translating to greater torque output.

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

• JA: Signifies the inclusion of keyed internal components (gerotor set and shaft). This is a critical feature for high-stress applications, preventing internal slippage and ensuring long-term reliability.

• J: Designates the port thread standard, in this instance, JIS (Japanese Industrial Standards) taper threads, which is essential for proper hydraulic hose and fitting compatibility.

This precise naming convention eliminates ambiguity, ensuring that the motor you source meets the exact technical requirements of your application.

Key Features and Procurement Advantages

When evaluating hydraulic motors, the CR-04-2P4-30-JA-J offers a compelling set of features that translate directly into operational benefits and long-term value.

1. Enhanced Torque Output for Demanding Tasks: With a displacement of 25 cm³/rev, this motor generates approximately 25% more theoretical torque than a 20 cm³/rev model under the same pressure. This makes it ideally suited for applications requiring higher rotational force to overcome heavy loads, such as driving larger wheels or powering heavy-duty augers.

2. Superior Durability with Keyed Internals (JA): The integrated keyed gerotor and shaft assembly is a hallmark of robustness. This design ensures that torque is transmitted positively, eliminating the risk of internal slippage that can occur under high shock loads or during frequent direction changes. For procurement, this means reduced failure rates, less downtime, and a lower total cost of ownership.

3. Optimized Low-Speed Performance: The gerotor design is inherently capable of providing exceptionally smooth rotation at very low speeds, even under one revolution per minute. This precise control is essential for applications like conveyor indexing, precise positioning, and mixer drives, where jerky motion is unacceptable.

4. High Power Density in a Compact Frame: The motor delivers significant power from its compact Frame Size 04 housing. This allows OEMs to design more powerful machinery without increasing the envelope size, a critical factor in competitive markets like compact construction and agricultural equipment.

5. Global Standard Compliance for Easy Integration: The use of SAE flanges and JIS ports, both widely accepted standards, ensures straightforward installation and integration. This simplifies the procurement of ancillary parts and reduces engineering time for machine builders.

Target Applications and Industry Use Cases

The robust performance profile of the CR-04-2P4-30-JA-J makes it a versatile component across multiple industries. Procurement teams will encounter demand for this motor in sectors including:

• Construction Machinery: Wheel drives for compact track loaders and skid-steer loaders, swing drives for mini-excavators, and drive units for vibratory rollers.

• Agricultural Equipment: Auger drives on grain carts, feed mixer mechanisms, hydraulic fan drives, and planter row unit drives.

• Material Handling: Drive wheels for electric pallet jacks and walkie stackers, as well as powered roller drives in conveyor systems.

• Specialized Industrial Applications: Winches, capstans, and rotation devices for packaging, recycling, and forestry machinery.
