Safety Warning
When using Lovejoy products, you must follow these instructions and take the following precautions. Failure
to do so may cause the power transmission product to break and parts to be thrown with sufficient force to
cause severe injury or death.

Refer to this Lovejoy Catalog for proper selection, sizing, horsepower, torque range, and speed range
of power transmission products, including elastomeric elements for couplings. Follow the installation
instructions included with the product, and in the individual product catalogs for proper installation of power
transmission products. Do not exceed catalog ratings.
During start up and operation of power transmission product, avoid sudden shock loads. Coupling assembly
should operate quietly and smoothly. If coupling assembly vibrates or makes beating sound, shut down
immediately, and recheck alignment. Shortly after initial operation and periodically thereafter, where
applicable, inspect coupling assembly for: alignment, wear of elastomeric element, bolt torques, and flexing
elements for signs of fatigue. Do not operate coupling assembly if alignment is improper, or where applicable,
if elastomeric element is damaged, or worn to less than 75% of its original thickness.

Do not use any of these power transmission products for elevators, man lifts, or other devices that carry
people. If the power transmission product fails, the lift device could fall resulting in severe injury or death.

For all power transmission products, you must install suitable guards in accordance with OSHA and
American Society of Mechanical Engineers Standards. Do not start power transmission product before
suitable guards are in place. Failure to properly guard these products may result in severe injury or death
from personnel contacting moving parts or from parts being thrown from assembly in the event the power
transmission product fails.
If you have any questions, contact the Lovejoy Engineering Department at 1-630-852-0500.

Lovejoy offers four types of elastomer designs to allow for additional
flexibility in addressing specific application requirements. One piece designs
are used in the “L” and “AL” models (referred to as spiders) and multiple
part “load cushions” are used in the “C” and “H” model couplings. The load
cushions are in sets of 6 to 14 pieces depending on coupling size.

The selection process for determining the proper jaw coupling size
and elastomer requires using the charts shown on the following
pages. There are three components to be selected, two hubs and
one elastomer. When the shaft size of the driver and driven of the
application are of the same diameter, the hubs selected will be
the same. When shaft diameters differ, hubs selected will differ
accordingly.

■■Environmental conditions (i.e. extreme temperature, corrosive
conditions, space limitations)
SP
Design Torque = Nominal Torque x Application Service Factor
Refer to the maximum RPM value (page JW-22) for this elastomer
torque capability to ensure that the application requirements are
met. If the requirement is not satisfied at this point, another type
of coupling may be required for the application. Please consult
Lovejoy engineering for assistance.
Step 6:Compare the application driver/driven shaft sizes to the maximum
bore size available on the coupling selected. If coupling bore size
is not large enough for the shaft diameter, select the next largest
coupling that will accommodate the driver/driven shaft diameters.
Refer to Chart 3 (page JW-9).
Step 7: Using the UPC number selection table (pages JW-11 or JW-12),
find the appropriate Bore and Keyway sizes required and locate the
Lovejoy UPC number.

in the appropriate column is greater than or equal to the Design

The Application Service Factor for an electric motor with standard
torque driving a rotary pump is 1.25. The value of 1.25 is found

Step 5: Using the Jaw Nominal Rated Torque Chart 3 (page JW-9),
the NBR elastomer column is used to determine the proper
coupling size. Scanning down the NBR column, the first entry to
accommodate the Design Torque value of 875.35 in-lb is the size
L150 with a nominal torque rating of 1,240 in-lb. Referring to page
JW-20, the maximum RPM of 1,800 on the electric motor of the
application does not exceed the 5,000 RPM maximum allowed for
the L150 size coupling with an NBR elastomer.
SP
The second bore size to be located is for the 1.75 inch shaft on
the pump. Scan down the Bore/Keyway column to the 1-3/4 inch
bore entry. Read across to the L190 column to locate the Lovejoy
UPC number of 12299. This number should be prefixed with the
Lovejoy UPC number of 685144.
T
The first bore size to be located is for the 2 inch shaft on the
electric motor. Scan down the Bore/Keyway column to the 2 inch
bore entry. Read across to the L190 column to locate the Lovejoy
UPC number of 12303. This number should be prefixed with the
Lovejoy UPC number of 685144.
Step 4: Using the Spider Performance Data Chart 2 (page JW-9),
select the elastomer material which best corresponds to your
application. Since there are no special environmental conditions,
the operating temperature is 72° F and less than 1° of angular
misalignment is required, the NBR elastomer material is selected.

Step 1: Determine the Nominal Torque:
Nominal Torque CJ
Step 6: Compare the application driver/driven shaft size to the maximum
bore available in the coupling selected (page JW-9). The electric
motor (driver) of this application has a shaft size of 2.0 inches
and the pump (driven) has a shaft size of 1.75 inches. The L150
coupling has a maximum bore less than the driver shaft size.
Continuing down the Maximum Bore column, in Chart 3 (page
JW-9), the L190 size is found to have a maximum bore size of
2.125 and is able to accommodate the driver/driven shaft sizes.
Therefore, the proper coupling size for this application is a
Lovejoy L190 with an NBR elastomer.
JIS
A coupling is needed to connect a 20 HP standard electric motor rated at
1,800 RPM to a rotary pump. The shaft size of the electric motor (driver)
is 2.0 inches and the pump (driven) is 1.75 inches. There are no special
environmental conditions and the general operating temperature is normal
room temperature of 72° F. Less than 1° of misalignment is expected.

URETHANE – Urethane has greater torque capability
than NBR (1.5 times), provides less dampening effect,
and operates at a temperature range of -30° to 160° F
(-34° to 71° C). Good resistance to oil and chemicals.
Not recommended for cyclic or start/stop applications.

SOX (NBR) Rubber – Nitrile Butadiene (Buna N)
Rubber is a flexible elastomer material that is oil
resistant, resembles natural rubber in resilience and
elasticity and operates effectively in temperature
range of -40° to 212° F (-40° to 100° C). Good
resistance to oil. Standard elastomer. (Also applies to
SXB Cushions.)
