The Kawasaki Staffa HMB030/S/21 is a compact fixed displacement radial piston hydraulic motor delivering 442 cc/rev displacement with a 17-tooth BS3550 splined shaft engineered for applications requiring positive torque transfer and simplified coupling installations in space-constrained environments. The splined shaft configuration eliminates keying operations and provides superior torque transmission capabilities compared to parallel keyed alternatives, while maintaining the compact form factor essential for installations where mounting space is at a premium.
