The Tokyo Keiki CR-07-2S4-30-JA is a CR Series internal gear hydraulic motor designed for low-speed, high-torque rotary drive applications. It converts hydraulic pressure and flow into stable mechanical rotation, making it suitable for systems that require smooth torque output, controlled speed, and reliable hydraulic drive performance.

This model has a displacement of 106cm³/rev, rated working pressure of 21MPa, maximum working pressure of 28MPa, rated torque of 310N·m, and maximum torque of 415N·m. With a rated speed of 465min⁻¹ and approximately 11.0kg body weight, the CR-07-2S4-30-JA provides a practical balance of torque output, compact installation, and hydraulic system reliability.

The model code provides important configuration information. The “2” indicates 2-bolt oval flange mounting, the “S” indicates straight thread ports in the motor body, and the “4” indicates a 1-1/4 inch parallel keyed shaft. Because this model does not include “D” in the code, it is normally treated as an internal drain configuration. This structure is useful for hydraulic systems that require compact mounting, strong shaft transmission, and straight thread port connection.

The CR-07-2S4-30-JA can be used in conveyors, winches, material handling systems, industrial machinery, mobile hydraulic equipment, agricultural machinery, marine deck equipment, and production line auxiliary systems. It is also suitable for hydraulic motor replacement, machine repair, and spare parts maintenance projects.

For replacement applications, the complete model number CR-07-2S4-30-JA should be checked carefully. Similar CR Series motors may have different displacement codes, mounting types, porting styles, shaft ends, drain configurations, rotation directions, and seal options. Before ordering, please confirm the original motor label, shaft diameter, mounting flange, port thread, hydraulic pressure, flow requirement, drain arrangement, and machine installation space.

Dengfeng supplies Tokyo Keiki hydraulic motors, hydraulic pumps, valves, servo drives, PLC modules, industrial control components, and automation spare parts for machine repair and production line maintenance. Before shipment, we can check the model label, shaft condition, port condition, mounting surface, appearance, and packaging according to your request.
