7860C-RS Radial Spinner System
Installation Guide
Introduction
The 7860C-RS radial spinner system is a precision, air-actuated spinner
device that produces a narrow radial output band ideal for coating the
interior walls of cylindrical shaped parts. Air pressure is released to the
colleted air motor to spin the radial disc and shaft assembly. During this
radial spin cycle, fluid is dispensed onto the spinning disc, causing it to
be distributed in a narrow band-like pattern onto the side wall.
The spinner disc and shaft assembly have a shaft length of 70mm
(2.75"), with disc sizes ranging from 9mm (0.354"), 12mm (0.473"),
15mm(0.590"), and 19mm (0.745"). The radial spinner system is easy to
use and will operate for many millions of cycles without maintenance.

Installation
Prior to installing this
system, read the associated
reservoir and ValveMate™
7160RA controller operating
manuals to become familiar
with the operation of all
components of the radial
spinner system.
NOTE: Refer to the
ValveMate 7160RA
controller operating
manual for air connection
instructions.
1. Mount the radial spinner bracket using
the rod provided or bolt it onto an
appropriate mounting fixture. Follow
these steps to install the radial spinner
valve:
a. Slide the valve up into the bracket
opening until it bottoms out at
the actuating air fitting. Secure in
place.
b. Install the special bent tip in the
rotating luer lock adapter. Make
sure the tip end is in the vertical
position.
c. Slide the air motor into the bracket
opening. Make sure the motor
collet does not make contact at
the bend of the dispense tip.

d. Insert the shaft into the collet.
Set the tip approximately
0.5mm (0.20") from the spinning
disc surface. Tip alignment
should be 2.5 mm (0.100") away
from the radial spinner shaft.
e. Realign the valve and motor
in the bracket as needed
to achieve recommended
clearances.
2. Connect the fluid feed hose to the
reservoir outlet and the valve inlet
port using the appropriate fittings
(supplied).
To pressurize
3. Connect the 4 mm diameter
air hose from the valve to
the 7160RA controller. The
white connector goes to the
ACTUATING AIR port. Make
sure the nozzle air is OFF and
set to 0 bar (0 psi).
NOTE: The NOZZLE AIR port
is not used for radial spinner
installations.
4. Connect the white and black
6mm diameter air hoses to
the air motor assembly: white
connects to the motor speed
control and black connects to
the F fitting (actual markings on
air motor).

NOTE: Set the tip approximately 0.5mm (0.020")
from the spinning disc surface. Tip alignment should
be 2.5mm (0.100") away from the radial spinner
shaft.
5. Connect the white and black
6mm diameter hoses to the filterregulator-lubricator assembly.
White connects to the oil recovery
bowl and black connects to the
control valve.
6. Fill the fluid reservoir. After filling,
secure the cover and connect the

the air tee using the flexible air
line (supplied). Attach the male
quick-connect in the air line to
the reservoir regulator and then
attach the white quick-connect
to the air tee. To pressurize the
system, slide the shut-off valve
in the air line toward the fluid
reservoir.
7. Set the reservoir pressure regulator
according to fluid viscosity: low for
thin fluids [0.07 to 0.2 bar (1 to
3 psi)] and higher for thicker fluids.
8. Set the 752V-UHSS valve (or other
appropriate valve model) stroke
control to achieve a desired flow
rate onto the spinning disc. Set the
flow to approximately one drop per
second.
9. Adjust the air motor RPM
using the speed control knob.
Turn the speed control knob
clockwise to reduce RPM and
counterclockwise to increase
RPM.
