Notes About This Catalog
 Wherever escalator types are shown, the standard escalator of that type is
assumed unless otherwise specified. For example, “J” means J escalators,
whereas “J Escal-Aire®” is used to indicated that specific sub-type.

 Most measurements are provided in both Imperial units (for the United States)
and metric units (for Canada, Mexico, etc.). If only one form of a measure-

Otis Elevator, January 2008

ment is provided, assume Imperial units (generally inches) unless otherwise
stated.

 Most Imperial measurements are rounded to the nearest tenth or hundredth

of an inch and most metric measurements are rounded to the nearest mil-
limeter.

©
 The size of early escalators (Imperial/pre-Metric) is obtained by measuring
between the balustrade panels or the glass panels. On Otis units, the step
width is 8 inches narrower than the escalator width. For example:

• A 32 R is 32 inches between the balustrade panels and has 24-inch

wide steps.

• A 40 UB or 40 J escalator is 40 inches between the balustrade panels

and has 32-inch wide steps.

• A 48 R escalator measures 48 inches between the balustrade panels

and has 40-inch wide steps.

 Escalators and Trav-O-Lators® designated 1000 mm, 900 mm, 800 mm, and
600 mm have steps or pallets that are exactly that width (there is no need to
add 8 inches on these units).
 Many of the pages in this catalog refer to Spare Parts Leaflets (SPLs) and the
older C-Leaflets where you can find additional information. You can access
these documents electronically through OtisWave or in paper form by calling
the OSC Library at (860) 286-6305. To facilitate your search, we’ve also
included the component code in which each C-Leaflet is found (for example:
c.c. 50).

Escalators are designated by either a metric measurement, an imperial measurement, or

both. This picture shows how those measurements are determined. Note that the imperial
measurement (shown top) is from the left balustrade panel to the right balustrade panel.
The metric measurement, however, indicates the nominal step width. This explains why
the two measurements do not convert properly between systems (why a 48-inch escalator
is also called a 1000 mm escalator). To avoid errors, measure the step or pallet width in
millimeters and provide that measurement to Customer Service.

 Escalator Parts
Step Chains
Refer to SPL 54-GAA26150E
How to Order Step Chain:
You need to order one axle for each step on your unit. If you have an odd number of steps, then
you would need an offset link.
Example:
An 85-step unit would need:
(8) 10-Folds = 80 Axles
(2) 2-Folds = 4 Axles
Otis Elevator, January 2008

(1) Offset = 1 Axle

85 Axles
Parts in the Step Chain section are sorted by escalator width, then by escalator type unless
otherwise indicated.

Steps
Refer to SPLs C-970F (in component code 50) and C-1090 (in component code 56)
Please keep the following in mind when measuring for steps: Measure the width of the tread and add eight inches.
NOTE 1: 26BR1 denotes black finish
26BR2 denotes gray finish
”removable” means tread is fastened from top
”non-removable” means tread is fastened from bottom
all treads are die-cast aluminum
NOTE 2: As a generalization, most step applications that had removable treads originally have been replaced by non-remov-
