General Instructions
About the manual
This manual contains the technical instructions for the Black Bruin BB and BBC series
hydraulic motors. Take these instructions into consideration when planning the use
of the product.
All information given in this manual is current and valid according to the information
available at the time of publication. The manufacturer reserves the rights to
implement changes without prior notice.
Please visit www.blackbruin.com for the most recent version of this manual. The
product datasheets and the 3D-models are available from the manufacturer by
request.
Intended use
Black Bruin BB and BBC series hydraulic motors are designed to be used as hub
motors on vehicles. They can also be used in other applications that need torque for
rotary movement.
Warranty
Check the package and the product for transport damage when receiving goods. The
package is not meant for long term storage; protect the product appropriately.
Do not dismantle the product. The warranty is void if the product has been
disassembled.
The manufacturer is not responsible for damages resulting from misinterpreted, non-
compliance, incorrect, or improper use of the product that goes against the
instructions given in this document.

Safety Instructions
The following instructions apply to all procedures associated with the motor. Read
these instructions carefully and follow them closely.
• Use necessary personal protective equipment when working with the motor.
• Support the motor properly. Make sure the motor cannot fall over or turn around
by accident.
• Use only appropriate equipment and attachments for lifting and transferring the
motor.
• Do not use magnetic lifting devices.
• Always use the lifting equipment properly and check the load-bearing capacity.
• Prevent unintended use of the motor during installation and maintenance
procedures by preventing pressurization of the hydraulic lines.
• The operating temperature of the motor may be over 60 ºC (140 °F), which is hot
enough to cause severe burns. Beware of hot hydraulic uid when disconnecting
the hydraulic connections.
Warning symbols
The following symbols are used in this manual:

Motor Description
Working principle
BB and BBC series motors are rotary-housing. This means the motor shaft and the
cylinder block remain in place while the motor is running.
Figure 2. The main components of the motor.
1. Shaft
2. Distribution valve
3. Cylinder block
4. Piston
5. Cam roll
6. Cam ring
7. Bearings
8. Housing
9. Hub
10. Shaft sealing
The rotation of the motor is achieved by feeding pressurized hydraulic uid through
the motor shaft to the distribution valve. The distribution valve directs the ow to the
pistons which are on a power stroke. Pressure pushes the pistons and cam rolls
outwards against the cam ring on the housing. The waveform of the cam ring
transforms the force into torque. When the pistons reach the end of the power stroke,
the distribution valve closes the ow to the pistons and switches the pistons to a
return stroke.The cam ring pushes the pistons back into the cylinder block preparing
them for the next outward power stroke.
Figure 3. Flow to the pistons.

tons.
