OMSY series cycloidal hydraulic motors are used in rock drills.

1.Low-Speed, High-Torque Hydraulic Drive
BMSY orbital motors provide high torque at controlled rotational speeds, making them suitable for hydraulic drive systems used in rock drilling and mining equipment.

2.Roller Gerotor for Efficient Hydraulic Power Transmission
The BMSY motor uses a roller gerotor set with rolling contact between the working elements, providing an efficient solution for hydraulic rotary drives in demanding equipment.

3.Designed for High Axial and Radial Loads
A tapered roller bearing-supported output shaft allows the BMSY motor to handle substantial axial and radial forces, making it suitable for demanding hydraulic drive applications such as rock drilling equipment.

4.Flexible Displacement and Mounting Options
With nine displacement sizes and multiple shaft, mounting and port configurations, the BMSY series can be matched to different hydraulic circuits and mechanical layouts used in rock drilling equipment.

5.High-Pressure Operation with Shaft Seal Protection
BMSY motors support high-pressure hydraulic operation and incorporate a high-pressure shaft seal and case-drain design to help manage shaft seal pressure during operation.
