The HDR Series worm gear reducers are
used in low to moderate horsepower
applications to reduce speeds and increase
torque. Worm gear reducers are available in
direct or indirect drive, direct drive models
are 56C flange mount with either right, left
or dual output shafts or a hollow bore
output. The indirect drive models are shaft
input-shaft output boxes for use with
sprocket or pulley drive systems. They
provide an effective low cost solution to
speed reduction and increased torque, with
higher tolerances for shock loading than
helical gear reducers.

Main gear is Albc3 which is
aluminum–bronze and much
harder than the normally
used phosphor–bronze.

Embedded oil seals
(double lip) prevent
leakage on both ends.

Two tapered
roller bearings
on both shaft ends.

Universally interchangeable

compact design assures you

better OEM replacement

In order to select a gearbox speed reducer,
you will need to determine the required
torque and service factor for the application.
The table to the right will assist in
determining the service factor. For service
factors above 1.0, multiply the required
torque by the service factor.

Example: Review the mechanical ratings
table (next page): A torque requirement of
675 in. lbs. and a ratio of 20:1 (88 RPM),
you would choose a box size 175 and it
would require a 1.26 input HP, or a 1.5 HP

motor. However, if the service factor is
determined to be 1.4, then your required
torque would be 1.4 x 675, or 945 lbs in. In

D-2

this case you would select a box size
237 rated at 1195 in. lbs and require an
input HP of 2.06, or a 2 HP motor.
