The Tokyo Keiki CR-09-4P8-30-D-JA-J is a 153 cm3/rev hydraulic motor for high-torque, low-speed rotary drive applications. It is part of the CR Series internal gear motor range and is suitable for industrial and mobile hydraulic circuits that require stable torque output, compact flange mounting and a spline shaft connection.
This CR-09 motor operates at a rated working pressure of 21 MPa and delivers a rated torque of 460 N.m. With a rated flow of 60 L/min and rated speed of 315 min-1, it is suitable for hydraulic equipment where controlled low-speed rotation is required.
The 4P8 configuration includes a four-bolt flange mount, Rc1/2 tapered threaded main ports and a 1-1/4 inch involute spline output shaft. The spline shaft supports direct coupling with compatible hubs, gear drives and transmission components where a keyed shaft arrangement is not suitable.
The D designation identifies an external Rc1/8 drain port. Install the drain line with minimal restriction and maintain case pressure within the specified limit to support shaft-seal performance and reliable motor operation.

Installation and Selection Notes
Confirm the complete model code before replacement because CR Series motors vary by displacement, mounting pattern, port type, output shaft and drain arrangement. This version uses a four-bolt flange, Rc1/2 tapered ports and a 1-1/4 inch involute spline shaft. Verify hub compatibility, spline engagement length, system flow, pressure differential and rotation direction before installation.
Do not apply unverified radial or thrust loads directly to the shaft. For chain, belt or gear drive applications, confirm shaft-load suitability with the equipment designer.
