VANE CROSSING VANE
The Rineer patented vane crossing vane design produces much higher volumetric and mechanical efficiencies than is possible with a standard vane type design. This design provides a sealing vane between cavities to improve mechanical and volumetric efficiencies.
STARTING AND STALL TORQUE
The Rineer motor produces torque curves which are virtually flat with starting and stall torque equal to approximately 90-94% of theoretical torque.
SEALS
Buna N seals are supplied as standard on the Rineer 15 Series motors. Viton seals may be ordered as an option.
FILTRATION
25 micron minimum
FLUID
We suggest premium grade fluids containing high quality rust, oxidation and foam inhibitors, along with anti-wear additives. For best performance, minimum viscosity should be maintained at 100 SSU or higher. Fluid temperature should not exceed 180o F. Elevated fluid temperature will adversely affect seal life while accelerating oxidation and fluid breakdown. Fire resistent fluids may be used with certain limitations. Contact Rineer for additional information.
MOUNTING
The mounting position is unrestricted. The shafts, pilots, and mounting faces should be within .002 TIR.
ROTATION
The 15 Series Motor rotates equally well in either direction and smoothly throughout its entire pressure and speed range. Looking into the end of the shaft, rotation is clockwise when oil is supplied to port "A".

MORE POWER STROKES PER REVOLUTION
The 15 Series has four stator cavities and 10 rotor vanes. Each rotor vane works in each stator cavity once per revolution, which results in 40 power strokes per revolution. This helps produce higher mechanical efficiency and flatter torque curves.
BEARING LOADING
The bearings in the 15 Series can accept radial load per the radial capacity chart. Thrust load is not recommended under most conditions. Consult with a Rineer Application Engineer for optional bearing configurations to match your application.
ROTATING GROUP - 1S or 1H
Under most operating conditions, 1S (standard rotating group parts) should be used. Under some high speed conditions 1H can be specified.
HORSEPOWER LIMITATION
Maximum horsepower limitations may vary with different applications. When using the 15 Series Motor above 75 HP, consult a Rineer Application Engineer.
INTERMITTENT CONDITIONS
Intermittent conditions are to be less than 10% of every minute.
CASE DRAIN
The 15 Series Motor is designed for either internal or external case drain. Two case drain ports are supplied. When using internal case drain, simply plug the two ports. When using external case drain, use the port at the highest elevation. We recommend case drain pressure of 35 PSI or less when using the standard seals.
CASE DRAIN CIRCULATION
Fluid should be circulated through the case when a temperature differential exists between the motor and the system in excess of 50o F. Should this occur, contact a Rineer Application Engineer.
TECHNICAL INFORMATION - RETRACTABLE SHAFT MOTOR
RETRACTING THE SHAFT
The shaft is spring loaded into the engaged position. Pulling on the knob attached to the shaft at the rear of the motor will move the shaft 1.25 inches into the motor.
CAUTION: Retracting the shaft must be done when the motor and driven mechanism are not in operation and are unloaded.
RETAINING SHAFT IN RETRACTED POSITION
The shaft is retained in the retracted position by inserting a 2.0 inch wide spacer between the rear housing and the knob attached to the shaft. Depending on the application and mounting position of the motor, the spacer design may vary. Spacers are not supplied with the motor.
RE-ENGAGING THE SHAFT
This is accomplished by releasing the shaft, then rotating it clockwise until the splines of the shaft line up and engage the splines of the driven mechanism.
CAUTION: Re-engaging the shaft must be done when the motor and driven mechanism are not in operation and are unloaded.
BEARING LOADING
The 15 Series Retractable is not suitable for applications which require radial or axial loading of the shaft.
MOUNTING
The mounting position is unrestricted.
CAUTION: The shaft extension and knob at the rear of the motor rotates when the motor is in operation.
