2. Collector Ring Maintenance
A. Lubrication
1. All bearings are lubricated for life at the factory.
Additional lubrication should not be required.
2. CAUTION: Do not apply any lubricants or
solvent cleaning agents to any part of the slip
ring.
B. Brush Holders
1. Make the first inspection shortly after installation
and before operation. Make continuing inspections
on a regular basis after every 200-400 hours of
operation under normal conditions.
C. Brush Holders
1. Inspect brush holders for proper alignment.
Locate brush holders so that the entire brush
contact surface rides squarely on the ring with the
brush moving freely in the brush holder. Position
brush holders so that the brush makes contact
with the middle of the conductor and is not offset.
2. Check brush holder clamps for tightness. Set
clamp bolts at 10 in-lb max.
3. To remove and replace the brush:
a) remove the clamp screw from the brush
holder
b) remove the screw from the brush lead
c) remove the brush holder
d) replace the brush
e) reassemble.
E. Brush Fit Inspection
1. Brushes must run at 90° ± 3° square on the rings.
If brush is not square, adjust position of brush
holder on brush post.
2. Brushes need not run on the center of the rings,
but there should be no forceful friction against the
insulators.
3. The brush spring cross-bar must be seated in the
brush slot.
Cross-bar Seated
in Brush Slot
Brush Holder
3. Inspect brush terminations at the holder to assure
that no external force is imposed on the holder.
We recommend flexible or soft wire leads for
these terminations. Use external clamps to
support the entire weight of the leads.
D. Brushes
1. Inspect for wear. If the distance from the top of
the insulator to the lower part of the brush spring
is 0.093" or less, replace the brush.

Maintenance
2. Collector Ring Maintenance (Cont.)
G. Rings
1. Inspect the ring surface for dirt, oxidation, or
other contaminants. A properly operating ring will
have a film that appears burnished in color with a
darker surrounding color where the brushes
track. If the ring requires cleaning, order Slip
Ring Polishing Kit #41286.
H. Electrical Connections
1. Inspect all electrical connections for corrosion
and tightness. Clean corroded parts with a wire
brush and/or muriatic acid. Loose and/or
corroded terminations will cause a concentration
of excessive heat.
I. Brush Rigging
1. Brush posts are supported between two outboard
bearings. The brush posts extend to the outboard
bearings and are secured by a notch in the
outboard
2. Spacing between the outboard bearings is critical
to assure the free rotation of the brush rigging.
The brush posts are cut to an exact length in
order to provide the proper spacing. Locate the
outboard bearings against the insulator and have
a 0.20" clearance without deformation of the
material. CAUTION: Do not over-tighten the
outboard brush post jam nuts. Make a final check
to assure there is no binding of the outboard
brush rigging or binding of brushes with insulator
barriers.
3. Periodically perform an inspection by removing the
enclosure and checking for condensation, water
and dust collection. If contaminants are found,
wipe the enclosure and the assembly with a lint
free cloth. If the problem persists, take steps to
remedy the leakage or condensation problem.
K. Slip Ring Storage
1. When storing the slip ring, keep it at room
temperature in a clean, dry, protective place.
Place self-contained or bagged absorbent material
in the collector ring enclosure during extended
periods of storage. Remove absorbent material
before putting collector ring into operation.
L. Serial Number
1. Make the following information available when
ordering replacement parts or discussing the slip
ring with the factory by recording the information in
the spaces provided here. This information is
located on your packing slip, factory invoice, and

J. Enclosure Inspection
1. Moisture is a major cause of slip ring
deterioration. Water will corrode parts and
breakdown insulation. Dust and dirt present
within the enclosure will effect the proper
operation of the assembly. Most dusts cause
excessive brush and slip ring wear, and
conductive dust, if allowed to accumulate, will
form a path for short circuiting.
2. A properly designed NEMA 4 enclosure will be
dust tight and watertight. However, NEMA 4
enclosures do not eliminate internal
condensation. Condensation can be eliminated
with the addition of a breather , drain, and a
thermostatically controlled heater.
