The Tokyo Keiki CR-08-4S4-30-D-JA-J is a 123 cm3/rev internal gear hydraulic motor designed for low-speed rotary drive systems requiring stable torque output and flange-mounted installation.
This CR-08 model provides a rated torque of 360 N.m at a rated working pressure of 21 MPa. With a rated flow of 60 L/min and rated speed of 395 min-1, it is suitable for hydraulic machinery where torque, speed and flow must be matched for dependable rotary motion.
The 4S4 configuration combines a four-bolt flange mounting arrangement, SAE O-ring hydraulic ports and a 1-1/4 inch parallel shaft with square key. This keyed shaft structure is suitable for coupling to sprockets, pulleys, gearboxes, drums and other mechanical drive components.
The D code identifies an external Rc1/8 drain port. The drain line should be installed with minimal restriction to control housing pressure and help maintain shaft-seal performance.

Installation and Selection Notes
Confirm the complete model code before replacement because CR Series motors differ in displacement, flange style, porting, shaft configuration and drain design. This model uses a four-bolt flange mount, SAE O-ring ports and a 1-1/4 inch keyed shaft. Connect the external drain line correctly and keep case pressure within the specified back-pressure limit. Verify hydraulic fluid compatibility, flow rate, pressure differential, rotation direction and shaft load before installation.
