Hydraulic Motors, TB Series, 7/8" SAE

Low speed, high torque hydraulic motors from Parker. Ideal for a wide range of medium to light-duty applications. Common replacements for CharLynn and TRW/Ross motors. (Note: Other TB series motors are available, call for pricing/availability.)

Features Include:

• High pressure shaft seal so external drains are not required
• Roller vane technology for automatic wear compensation
• Full flow internal cooling and flushing
• 4-Bolt mounting flange
• 1” shaft with keyway
• 1/2” NFPT O-ring ports
• Standard motors with AAAC have two coats of paint, AAAA motors have one coat.

Formula for sizing hydraulic GPM requirements for proper operation of specific equipment.
GPM = Cubin In of Displacement x Equipment RPM
231 Cubic Inches
Example: 4.0 Cu In motor x 120RPM brush = 480 divided by 231 constant - 2.078 GPM
Multiply GPM x 10% service factor, 2.078 x 10% = 2.29 GPM required for this application
