SG08-13T Hydraulic Swing Motor for Sumitomo SH200 SH210 Excavator

Premium SG08-13T Nabtesco Swing Motor (13-Tooth)

The SG08-13T swing motor is the legendary hydraulic rotational drive built on the Nabtesco SG08 architecture, specifically configured with a 13-tooth output pinion. Widely equipped on 20-ton class excavators like the Sumitomo SH200 and Case CX210, this motor ensures precise, high-torque slew movements under severe excavation loads.

Compatible with: Sumitomo SH200-5、SH200A3、SH210-5、SH210A3、SH210-6 CASE CX210、CX210B、CX225、CX225B

Critical Fitment Warning: 13-Tooth vs 14-Tooth

Please physically count the splines/teeth on your old motor's output shaft before ordering. The SG08-13T features exactly 13 teeth. It is NOT interchangeable with the SG08-14H (14-tooth) variant. Using the incorrect motor will cause catastrophic ring gear failure.
