Description
Coupling: For connecting an encoder to a 3/8” shaft
Coupling package: For connecting an encoder to 1/4”
or 5/16” diameter shaft*
*Package includes: One flexible coupling (1/2” I.D.) and three
reducing inserts (1/4”, 5/16”, 3/8”).
Flexible Shaft Couplings
The one-piece flexible coupling connects
the shaft of a cube-style encoder to an ancil-
lary equipment shaft without worry of mis-
alignment of rotary frequency. The coupling
ensures minimum windup, minimum rotary
oscillation, and no hysteresis.
Chariot
The Chariot is used to mount most cube-
style quadrature encoders and measuring
wheels. Made of anodized aluminum, the
chariot includes mounting hardware and
selectable pivotal points. Wheels, tires,
and flexible shaft couplings are sold sepa-
rately.

Tire Durometer
A Simpson 12” anodized aluminum measuring wheel is the right
choice to complete the setup of a length measurement system.
Whether the application requires one or two, Simpson’s measuring
wheels will perform accurately and reliably throughout the measuring
process. Also included on the measuring wheel is a printed align-
ment scale which assists in the installation and measurement of the
length measurement system. Simpson offers four replaceable
durometer tires that consist of a black tire that has a longer life span
and three non marking tires. The three non marking tires are for deli-
cate materials such as plastics, textiles, wood, metal and paper to
prevent tearing, damage or marking of delicate materials.
80A, black tire; longer service life for plastics, metals
83A, non-marking tire for textiles, medium textures
92A, non-marking tire for plastics, metals, coarse wood
70A, non-marking tire for soft textiles
