GENERAL DESCRIPTION
Bell Cup Assembly
All bell cups are made of high strength Titanium.
They are available in 65mm serrated, non-serrated
for base coat applications and 55mm or 65mm
serrated for clear coat and primer applications. A
30mm and 55mm aluminum bell cup is available
Air Bearing Turbine Assembly
The air bearing turbine assembly with bell cup
is mounted to the air manifold assembly with a
turbine retaining ring.
Air Manifold Assembly
The atomizer extension is angled at 60° for robot
applications. The fluid feed tube and fiber optic
turbine speed emitter are threaded into the front of
the manifold. The turbine, fluid, and air manifold
are separated from the bell plate assembly by five
sup-port rods. Nested between the manifolds and
the bell plate is the high voltage cascade.
Bell Plate Assembly
The bell plate assembly is designed to be at ground
potential when mounted to the robot plate com-
ponent within the tubing bundle assembly. The
air and fluid ports are compactly oriented for use
in robotic applications. The interior air supplies
are ported through the five support rods and also
directly tubed to the air manifold assembly. On
the exterior side of the bell plate, the ports are
provided with o-ring seals so that the atomizer can
be quickly mated and secured to the robot plate.
Robot Plate
The robot plate is a component of the tubing bundle
assembly and intended to be permanently mounted
to the robot. A wrist adapter is also available, which
matches the robot's mounting configuration. The
incoming air lines, fluid lines, low voltage cable,
and fiber optic cable are connected to the fittings
provided on the back of the robot plate. The bell
plate of the atomizer assembly is secured to the
robot plate with a threaded retaining ring.
Valve Manifold
Configured to allow two colors to be loaded at one
time. The manifold can be converted for single
paint supply by installing valve port plugs (77620-
00 Valve Plug Kit).
Break-Away Feature (Optional)
The RMA-303 can be converted to have a break-
away feature, by replacing the five (5) stainless
steel screws with five (5) special designed plastic
screws (77524-00). This feature is meant to re-
duce the damage to the atomizer, robot, etc. If a
collision occurs, the five (5) plastic break-away
screws fail and the atomizer will break free. This
will leave the break-away ring and the mounting
ring attached to the robot.
