Description
Char-Lynn J Series motors provide a lot of power from a
very small package. Up to 5 kW [6 1/2 HP] of power. These
motors are 61 mm [2.4 in] in diameter and 104 to 130 mm
[4.1 to 5.1 in] in length.
The J Series motor shaft and seal allows high case pressure
up to 76 bar [1100 PSI] return line pressure without case
drain line. When a case drain line is used a 220 bar [3190
PSI] peak pressure is allowed in the return line.

* Maximum pressure at
motor inlet port is 220
Bar [3190 PSI] without
regard to ∆ bar [∆ PSI] and/
or back pressure ratings or
combination thereof.
Note:
To assure best motor life,
run motor for approximately
one hour at 30% of rated
pressure before application
to full load. Be sure motor is
filled with fluid prior to any
load applications.
∆ Pressure:
The true ∆ bar [∆ PSI]
difference between inlet
port and outlet port.
See individual shafts for
maximum torque recom-
mendation. Splined shafts
are recommended for those
applications subject to
frequent reversals.
Continuous Rating:
Motor may be run
continuously at these ratings
Intermittent Operation:
10% of every minute
Peak Operation:
1% of every minute
Recommended Fluids:
Premium quality, anti-wear
type hydraulic oil with
a viscosity of not less
than 70 SUS at operating
temperature.
Recommended System
Operating Temp.:
-34°C to 82°C
[-30°F to 180°F]
Recommended Filtration:
per ISO Cleanliness Code

The hydrodynamic bearing
has infinite life when
shaft load ratings are not
exceeded. Hence, the shaft
side load capacity is more
than adequate to handle
most externally applied
loads (such as belts, chains,
etc.), providing the motor to
shaft size is applied within
its torque rating.
Allowable side load chart,
shaft load location drawing
(right) and load curves
(below) are based on the
side or radial loads being
applied to shaft at locations
A, B, and C, to determine
the shaft side load capacity
at locations other than those
shown use the formula
(shown below). For more
information about shaft side
loads on Char-Lynn motors
contact your Eaton repre-
sentative.

The J Series now offers check
valves in the motor as a
standard feature. This addition
reduces the case pressure
in the motor to the return
pressure of the system when
the case drain is not used.
For return pressures higher
than the rated pressures (see
chart) the external case drain
can be connected. If the case
drain line is needed, connect
drain line to assure that the
motor will always remain full
of fluid.
Case Drain Advantage
In addition to providing
lower case pressures for
motors connected in series,
there are advantages for
adding an external case
drain line to motors with
normal case pressures as
well. These advantages are:
Contamination Control —
flushing the motor case.
Motor Cooler — exiting oil
draws motor heat away.
Extend Motor Seal Life —
maintain low case pressure
with a preset restriction
installed in the case drain line
Example:
A 14 Bar case pressure will
cause a load of 40 kg, so
the allowable thrust load will
be 82 kg plus 40 = 120 kg
kg pushing inward on shaft.
Tension load is 82 kg under
all case pressure conditions.
Example:
A 200 PSI case pressure will
cause a load of 88 lbs, so
the allowable thrust load will
be 180 lbs plus 88 = 268
lbs pushing inward on shaft.
Tension load is 180 lb under
all case pressure conditions
Note:
J Series motors can be
connected in parallel or in
series.
Case pressure will add to
the allowable compressive
thrust load. Case pressure
will push outward on the
shaft at 20 kg/7 Bar [44
lb/100 PSI].

The following 16-digit coding system has been developed
to identify all of the configuration options for the J motor.
Use this model code to specify a motor with the desired
features. All 16-digits of the code must be present when
ordering. You may want to photocopy the matrix below to
ensure that each number is entered in the correct box.
