Product Overview

 

The BMRS series 250cc cycloidal hydraulic motor is a shaft-distribution hydraulic motor adopting advanced Geroler® roller stator-rotor technology, with a geometric displacement of 253.3 cm³/rev (approximately 250cc). This model is equipped with an SAE 2-bolt mounting flange, a 1-inch (25.4mm) cylindrical straight shaft, and 7/8-14 SAE O-ring oil ports, which are internationally universal standard configurations. The motor features an axial oil distribution structure and an inserted column type stator-rotor pair design, boasting the characteristics of high starting torque, stable operation, and a compact structure. It is an ideal alternative to international brand models of the same specification such as Danfoss OMR and Eaton 2000 series. It is widely used in fields such as agricultural machinery, engineering machinery, material handling, and industrial equipment.
