Product Overview

 

The BMR series 2-bolt hydraulic motor is a compact power unit designed to offer excellent compatibility and convenience for direct replacement. This product is specifically optimized to be compatible with the widely used WR series, 151 series hydraulic motors on the market, as well as standard OMR (Oildyne®) interface slide valves. Its core adopts mature gerotor/geroler technology, inheriting the classic advantages of this technology such as stable low-speed operation and high starting torque. Meanwhile, through the standardized 2-bolt flange interface, it provides users with a highly flexible and space-saving solution during equipment maintenance, upgrading, or OEM design, simplifying the inventory and installation processes.

 

Features and Advantages

 

1. Excellent compatibility and interchangeability
◦ Plug-and-play replacement: The core value of this product lies in its direct physical and hydraulic interface compatibility. Its mounting flange, port positions, and valve connection bolt patterns are all designed to perfectly match the specified WR series, 151 series, and OMR slide valves. Replacement can be completed without modifying the mounting plate or pipeline layout, significantly reducing maintenance downtime and the complexity of retrofitting.
2. Compact and efficient space utilization
◦ 2-bolt flange design: Compared with traditional 4-bolt or larger flanges, it greatly saves installation space, enabling the motor to be easily integrated into equipment with limited space. It is particularly suitable as an auxiliary function drive or the main drive of compact machinery.
3. Reliable cycloid technical performance
◦ Low speed and high torque: The cycloid gear pair design ensures the motor runs smoothly at low speeds and can provide high starting torque, suitable for directly driving loads such as drums, winches, and conveyor belts.
◦ High volumetric efficiency and durability: Precise internal design and wear-resistant materials ensure efficient energy conversion and a long service life. It can perform reliably even under working conditions of frequent starts and stops or continuous operations.

 

Application fields

 

Thanks to its compact size, high compatibility, and reliable performance, this series of motors is widely used in fields requiring standardized replacement or compact design:
• Agricultural machinery: drives for augers and grain unloading tubes of combine harvesters, metering devices of seeders, and hydraulic drive accessories of tractors (such as spray pumps).
• Material handling equipment: drive rollers of conveyors, small winches or hoists, and rotating mechanisms of packaging machinery.
• Industrial and construction equipment: drives for discharge doors of concrete mixers, drives for augers or fans of snow sweepers, and drives for brushes of industrial cleaning equipment.
• Marine and special vehicles: deck machinery (such as small windlasses), and drives for auxiliary functions of sanitation vehicles.
