SlimCellClassicDS Low profile load cell for use
with either rotating shafts
or dead shaft rollers Low profile design reduces width
requirements of machine frame. Low friction bearing design ideal
for low tension applications. Extends usable tension range of
your machine (by measuring
both low and high tensions). Competitively priced alternative
to UPB style load cells. Maintenance-free bearing with
lifetime lubrication. Easily oriented to any web path
by merely rotating the
transducer (if the wrap angle
changes), no remounting
necessary. Available in two sizes and seven
different capacities (10 to
1,000 lb.) (45 N to 4,500 N). Designed to comply with NEMA
4x, IP65 standards. Completely sealedcorrosion
resisting, chemical resisting
(Stainless Steel 410) water
resisting, and dust sealed. Accommodates standard
roller-shaft diameters. 500-1000% Overload Ratings. Optional pillow block style
mounting bracket. CE compliant.
Performance Benefits
Cleveland Motion Controls Slim Cell
Classic is part of the Cleveland-Kidder
®
Tension Transducer family. With a unique
new low-profile design, it sets the standard
for either new machinery or for retrofits
where space is tight. With a dust sealed,
corrosion resisting, water resisting design,
it is ideal for use in demanding industrial
environments.
The Slim Cell Classic can be used with
either rotating shafts or dead shafts and
has a flat cylindrical shape. It is designed
to reduce the required side-frame-to-side-
frame width of the machine. It is also an
improved alternative to the UPB style load
cell because it can be rotated so that the
maximum tension load output is obtained
at any web force direction. (A UPB load
cells output is a function of the web force
direction and is severely reduced in some
orientations.)
The Slim Cell Classic includes a small
diameter maintenance-free bearing with
very low friction. It is ideal for low tension
applications with rotating shafts where the
size of the bearing and bearing friction
become a major contributing component to
the web tension. Shafts are easy to mount.
Shaft adapters are provided to accommo-
date standard shaft diameters. The shaft
fits into the adapter bore and it is held in
place with set screws. This eliminates the
need for a precision press fit.
Design Features
Cleveland Motion Controls Slim Cell
Classic accommodates any web path.
To orient the load cell, just loosen the
three mounting bolts, then rotate the
load cell body so that the orientation
sign is aligned with the bisector of the
wrap angle.
The Slim Cell Classic is made of
corrosion resisting stainless steel and
it is completely sealed to resist water
migration. It utilizes a low friction
labyrinth seal. The bearing utilizes
a synthetic lubricant, providing for
lifetime lubrication and low friction.
Slim Cell design enables it to be
mounted either inside or outside of
the machine frame. The Slim Cell is
typically applied in pairs, one on each
side of the machine. A pillow block
style bracket is also available as an
option. The Slim Cell Transducer has
force ratings from 10 to 1000 lbs. (45
N to 4500 N), accommodating a wide
range of tensions. The load cells
ability to accommodate such a wide
tension range makes it very adaptable
to a number of web tension
applications.

ORDERING PROCEDURE:
Slim Cell part numbers are configured according to your
requirements:
1. Calculate the Maximum Working Force (MWF) rating
from the Sizing Calculation equation. From the Part
Number Configurator, select a Load Cell Rating that
equals or exceeds the MWF from your sizing calculation.
This becomes position 1 of your part number.
2. Refer to Table 2, Slim Cell Body Size: Roller Shaft
Diameter vs. Load Cell Rating. Determine the diameter
of your roller shaft and select the Slim Cell Body Size
(SLM 1 or 2) that accommodates both your load cell
rating and shaft diameter. Refer to the Part Number
Configurator. The Roller Shaft Diameter and Load Cell
Body Size become positions 2 and 3 of your part
number. (Note: It may be necessary to turn down the
end of your roller shaft on a lathe to accommodate
the roller diameter choices offered.)
3. Refer to Table 3, Installation Choices and the Part
Number Configurator. The Slim Cell may be mounted
inside or outside the machine frame, or mounted on top
by utilizing the optional pillow-style mounting bracket.
The Slim Cell back plate is supplied with a through hole
(H) or blank, without a through hole (B). The Slim Cell
back plate is offered either with an alignment pilot (P)
or flush mount (F). Determine the type of back plate
required for your installation (BF, BP, HF, HP). The Load
Cell Back Plate becomes position 4 of your part
number.
4. Determine if your roller shaft is rotating or stationary.
The Roller Shaft Type becomes position 5 of your part
number.
Example: If you calculate a MWF of 21 lb., you have a
rotating roller shaft and your shaft diameter is 0.750
inches. Your installation does not require a through hole
in the back plate and you are flush mounting the Slim Cell
inside the machine frame. Your part number is
25-0.750-SLM1-BF-RS.
5. If you require the optional mounting bracket, order it
separately. Refer to the chart below:
6. Obtain pricing and delivery information by contacting
a CMC Sales Representative, Distributor or the factory.
