LOW SPEED, HIGH TORQUE MOTORS
working together for better solutions
Wide range of hydraulic motors & valves
The hydraulic motors have an advantage of small volume, high efficiency, low noise,
etc. and can be used in a wide field of application such as: Construction equipment,
Agricultural equipment, Plastic equipment, Mining equipment, Material Lifting
equipment, Forestry equipment, Lawn and turf equipment, Machine tools and
stationary equipment, Marine equipment,etc.

Usage Guide
Dear consumer,
In order to make the hydraulic motor work in optimal situations, we sincerely recommend the following:
1. A simultaneous max speed and max pressure is not recommended.
2. The motor can be used in parallel or series. But the installation of a drain line is necessary when back pressure is over 5 Mpa (72 PSI).
3. Filtering and oil cleanliness: a return filter should be installed in the system with a rating in the range of 10~30 um. The ISO level of the oil is to be no more than 19/16.
4. The optimum operating situation should be at the 1/3~2/3 of the continuous operation.
5. Make sure the motor is always filled with oil before operating.
6. In order to obtain longer life of the motor, we recommend to operate the motor at first for 30 minutes under 30% of rated pressure.
7. Maximum operating temperature: 80°C.
8. Recommended fluid: Anti-wear type of hydraulic oil. Viscosity: 37-73cst. Filtration: ISO19/16

BM1 Motor
BM1 series motor is a small volume,
spool valve gerolor gearset, economical
type motor.
Characteristic features
• Compact design of spool and gear set, which provide
small volume, high power and low weight.
• Credible design of our shaft seal, which can bear high
pressure and be used in parallel or in series.
• Direction of shaft rotation and speed can be controlled
easily and smoothly.
• Best combination of efficiency and economy in
medium load applications.

Notes 1. Continuous data: The Max. Value of operating motor continuously.
2. Intermittent Data: The Max. Value of operating motor is 10 % per minute.
3. A simultaneous max. RPM and max. pressure is not recommended.
4. The Conversion Factors are on page 4.
5. Optimum operating situation should be at the 1/3~2/3 of the continuous operation.

BM2 Motor
BM2 series motor is a medium, spool valve type
motor, that can bear higher pressure than BM1.
Characteristic features
• I t adopts the gerolor design. Has higher efficiency than our
BM1 series.
•C
redible design for shaft seal, which can bear high pressure
and can be used in parallel or in series application.
• Direction of shaft speed can be controlled easily and smoothly.
• Best efficiency and economy in medium load applications.

Notes 1. Continuous data: The Max. Value of operating motor continuously.
2. Intermittent Data: The Max. Value of operating motor is 10 % per minute.
3. A simultaneous max. RPM and max. pressure is not recommended.
4. The Conversion Factors are on page 4.
5. Optimum operating situation should be at the 1/3~2/3 of the continuous operation.

BM5 Motor
The BM5 is a large volume, disc valve, high
pressure motor with radial bearings design
and can bear greater load.
Characteristic features
• Advanced design in disc distribution flow, which can
provide better performance at low speed.
• The valve can automatically compensate for the
wear, so the volumetric efficiency is higher.
• Double taper roller bearings permit high radial
loads. The motors can be used on heavier vehicles in
traction drive applications.

BM5S Bearingless Motor
The BM5S is the bearingless motor of BM5 family,
large volume disc valve, high pressure motor.
Characteristic features
• Advanced
design in disc distribution flow, which can provide
better performance at low speed.
• The valve can automatically compensate for wear, so a higher
volumetric efficiency can be obtained.
Main Specification
The main specification and performance data are same as BM5, please refer to the
BM5 section on page 34-37.

LOW SPEED, HIGH TORQUE MOTORS
| 49
4K Motor
The 4K is a large volume that is between
our BM5 and BM6, disc valve, high
pressure motor with radial ball-bearings
design and can bear greater load.
Characteristic features
• The motor can be used in high pressure and high
torque applications.
• Advanced design in disc distribution flow,which can
provide improved performance at low speed.
• The valve can automatically compensate for wear, so
the volumetric efficiency is higher.
• Double taper roller bearings permit high radial
loads. The motors can be used on heavier vehicles in
traction drive applications.

Notes 1. Continuous data: The Max. Value of operating motor continuously.
2. Intermittent Data: The Max. Value of operating motor is 10 % per minute.
3. A simultaneous max. RPM and max. pressure is not recommended.
4. The Conversion Factors is on page 4.
5. Optimum operating situation should be at the 1/3~2/3 of the continuous operation.
50 | LOW SPEED, HIGH TORQUE MOTORS
BM6 Motor
The BM6 is a large volume, disc valve, high
pressure motor with a radial ball-bearings
design and can bear greater load and has
higher torque rating than our BM5.
Characteristic features
• The motor can be used in high pressure, so it’s max.
torque is higher than our BM5 motor.
• Advanced design in disc distribution flow, which
provides improved performance at low speed.
• The valve can automatically compensate for wear, so
the volumetric efficiency is higher.
• Double taper roller bearings permit high radial
loads. The motors can be used on heavier vehicles in
traction drive applications.

BM6S Bearingless Motor
The BM6S is the bearingless motor of
our BM6 family, large volume, disc valve,
high pressure motor.
Characteristic features
• Advanced design in disc distribution flow, which can
provide better performance at low speed.
• The valve can automatically compensate for wear, so
the volumetric efficiency is higher.
• Double taper roller bearings permit high radial
loads. The motors can be used on heavier vehicles in
traction drive applications.
Main Specification
The main specification and performance data are same as BM6, please refer to the
BM6 section on page 51-53.
