Congratulations on purchasing an Original Line Electric actuator from
Bimba. Our OLE and OLET actuators are designed, built, and tested to
provide the longest life, greatest durability, highest speed, and greatest
thrust per dollar. We look forward to serving your electric actuator needs
with the same responsiveness and engineering expertise you are accus­tomed to receiving for our pneumatic products.

Every OLE and OLET actuator is backed by a one-year warranty. Extend
it to a two-year warranty by registering on our website at

www.bimba.com/pdf/OLEwarrantyregistration.pdf.

1. Actuator-only Models

Installing your motor

a. Remove plug to provide access to
coupler. Use a 1/8 inch allen key.

b. Turn the actuator coupler so the clamp screw is aligned with the
access hole. Loosen coupler setscrew using allen key. Allen key

sizes are identied in Table 1.

Only loosen the clamp screw until it no longer secures the
motor shaft. Loosening it too much may result in the screw

!

falling out of the coupler, or binding against the actuator’s

inside wall.

Table 1

Actuator Allen Key Torque

75 5/64" 3.8 in-lbs.
150 3/32" 8 in-ibs.
350 3/32" 8 in-lbs.

Note: Torque range is ± 10%.

c. Mount motor to actuator, slip shaft into coupler. Secure motor to
actuator using 4 screws provided. Allen key sizes and torque values
are provided in Table 2. Be careful not to turn the coupler.

Table 2

Actuator Allen Key Torque

75 9/64" 12 in-lbs.
150 9/64" 12 in-lbs.
350 5/32" 35 in-lbs.

Note: Torque range is ± 10%.

d. Tighten coupler clamp screw so motor shaft is secured (refer to

Table 1 for torque specication). The coupler clamps around the
circumference of the motor shaft. The orientation of any at (or key-
way) on the shaft does not matter.

Tighten the coupler clamp screw to the torque value in Table 1.

!

e. Replace the coupler access plug.

DO NOT screw the plug in to a hard stop. Only screw it in far

enough so that the top of the plug is ush with the outside

!

surface of the actuator.
