ACTUATOR SELECTION
BASIC SELECTION
The procedure for
selecting an
Axidyne mechanical
actuator depends
on the complexity
of your application.
A simple but
thorough evaluation
of the application’s
motion requirements
is required
including the load
support system,
force requirements
and limiting factors.
Use the following
selection procedure
to help determine
the appropriate
actuator configuration
appropriate for
the application.

Procedure
1. List Key Requirements
Begin the selection process by identifying actuator key requirements
shown in the chart at left.
2. Determine whether a screw-style or belt-style
actuator is appropriate for your application.
The maximum operating speed of screw actuators is limited by the
critical speed characteristic of the screw. Belt-drive actuators are
used in applications where speed(consult factory for applications
over 100 inches/sec) and stroke length requirements exceed screw
critical speed limitations. Screw actuators provide finer resolution
and better repeatability than belt-drive units and are preferred for
short stroke, high move repetition requirements. (See “Limiting
Factors” in the “Comprehensive Product Selection” section of this
catalog.)
NOTE: Belt-drive actuators are NOT recommended for vertical
applications. Please consult the factory for further information.
3. Evaluate Load Support System.
The Tol-O-Matic Axidyne product family provides a selection of
three load carrier support and guidance systems.
A. Adjustable carrier bracket with self-lubricating plastic bearing rods
for BCS and BCB series cylinder-style actuators
The BCS series actuators provide good general purpose load
capacity and tracking accuracy. Periodic carrier adjustment
and bearing rod maintenance may be required.
B. Recirculating bearings on ground steel shafts for SLS10 Series
slide-style actuators. These actuators provide consistent carrier
tracking for full actuator life.

C. Heavy duty enclosed recirculating bearings in gothic arch
guide rail for B3S and B3B series actuators.
This series provides the highest load and moment load capacity
with consistent tracking and low carrier friction for the full
actuator life.
Review the application requirements and select the appropriate
actuator style. Then choose either metric or standard (inch) versions.
