The Tokyo Keiki CR-04-5G4-30-D-JA-J is a CR Series internal gear hydraulic motor built for low-speed, high-torque hydraulic drive applications. It converts hydraulic pressure and flow into stable rotary output, making it suitable for equipment that requires smooth torque delivery, controlled speed, and reliable hydraulic performance.

This model has a displacement of 62cm³/rev, rated working pressure of 21MPa, maximum working pressure of 28MPa, rated torque of 185N·m, and maximum torque of 245N·m. With a rated speed of 790min⁻¹, it is suitable for medium-duty hydraulic drive systems where compact size and reliable output are both important.

The CR-04-5G4-30-D-JA-J configuration includes 4-bolt square flange mounting, flange piping in the body, a 1-1/4 inch keyed shaft, and an external drain port. This structure is suitable for hydraulic systems that require secure mounting, stable piping connection, and improved drain management.

This hydraulic motor can be used in conveyors, winches, material handling equipment, industrial machinery, mobile hydraulic equipment, agricultural machinery, marine deck machinery, and production line auxiliary systems. It is also commonly used for hydraulic motor replacement, machine repair, and spare parts maintenance projects.

For replacement applications, the complete model number CR-04-5G4-30-D-JA-J should be checked carefully. Similar CR Series motors may have different displacement codes, mounting types, porting styles, shaft ends, drain configurations, rotation directions, and sealing options. Before ordering, please confirm the original motor label, shaft dimensions, mounting flange, port connection type, hydraulic pressure, flow requirement, and drain line arrangement.

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.
