Chapter 1 - Introduction
Product Description
404LXR Positioner
The 404LXR is a slotless, brushless linear servo motor/square rail bearing positioner housed within
a high strength, extruded aluminum body with magnetically retained protective seals. The
positioner is powered by a single rail of high energy rare earth magnets. Load bearing members
provide heavy load and moment capacity, dynamic stiffness and precise straightness and flatness
of travel. The positioner’s integral linear encoder provides high precision, non-contact positional
feedback with selectable resolutions from 0.1 to 5.0 microns. The positioner is also offered with
inductive proximity limit & home sensors, a “Quick Connect”, extended life, and a cable transport
system.
Unpacking
Unpacking
Carefully remove the positioner from the shipping crate and inspect the unit for any evidence of
shipping damage. Report any damage immediately to your local authorized distributor. Please save
the shipping crate for damage inspection or future transportation.
Incorrect handling of the positioner may adversely affect the performance of the unit in its
application. Please observe the following guidelines for handling and mounting of your new
positioner.
•Product may be heavy. Standard handling and lifting practices should be employed.
•DO NOT allow the positioner to drop onto the mounting surface. Dropping the positioner can generate
impact loads that may result in flat spots on bearing surfaces or misalignment of drive components.
•DO NOT drill holes into the positioner. Drilling holes into the positioner can generate particles and
machining forces that may affect the operation of the positioner. Parker will drill holes if necessary;
contact your local authorized distributor.
•DO NOT subject the unit to impact loads such as hammering, riveting, etc. Impacts loads generated by
hammering or riveting may result in flat spots on bearing surfaces or misalignment of drive components.
•DO NOT lift the positioner by cables or cable management system. Lifting positioner by cables or cable
management system may affect electrical connections and/or cable management assembly. The unit
should be lifted by the base structure only.
•DO NOT push in magnetically retained strip seals when removing positioner from shipping crate.
Damaging strip seals may create additional friction during travel and may jeopardize the ability of the
strip seals to protect the interior of the positioner.
•DO NOT submerge the positioner in liquids.
•DO NOT disassemble positioner. Unauthorized adjustments may alter the positioner’s specifications and
void the product warranty.

Return Information
Returns
All returns must reference a “Return Material Authorization”, (RMA), number. Please call your local
authorized distributor or Parker Customer Service Department at 800-245-6903 to obtain a “RMA”
number.
Repair Information
Out-of-Warranty Repair
Our Customer Service Department repairs Out-of-Warranty products. All returns must reference a
“RMA” number. Please call your local authorized distributor or Parker Customer Service
Department at 800-245-6903 to obtain a “RMA” number. You will be notified of any cost prior to
making the repair.
Warnings and Precautions
Hot Surfaces
DO NOT touch ‘carriage forcer’, (see page 7, Assembly Diagram, for component location), after
high duty operation. Unit may be too HOT to handle.
Electrical Shock
DO NOT take apart or touch any internal components of the positioner while unit is plugged into an
electrical outlet. SHUT OFF power before replacing components to avoid electrical shock.
High Magnetic Field
Unit may be HAZARDOUS to people with Pace Makers or any other 'magnetically-sensitive'
medical devices. Unit may have an effect on 'magnetically-sensitive' applications.
Ferrous Materials
The positioner's 'protective seals' MAY NOT keep out all small ferrous materials in applications with
air born metallic particles. The customer must take additional precautions in these applications to
keep positioner free of these highly magnetic particles.
Vertical Operation
The 404LXR is NOT recommended for vertical operation. The carriage and customer's load will fall
in power loss situations potentially causing product damage or personal injury.
General Safety
Because linear motors can accelerate up to 5 g's, and sometimes positioners move without
warning, keep all personnel away form dynamic travel range of positioner.

Specification Conditions and Conversions
Specifications are Temperature Dependent
Catalog specifications are obtained and measured at 20 Degrees C. Specifications at any other
temperature may deviate from catalog specifications. Minimum to maximum continuous operating
temperature range (with NO guarantee of any specification except motion) of a standard unit before
failure is 5 - 40 Degrees C.
Specifications are Mounting Surface Dependent
Catalog specifications are obtained and measured when the positioner is fully supported, bolted
down (to eliminate any extrusion deviation), and is mounted to a work surface that has a maximum
flatness error of 0.013mm/300mm (0.0005”/ft).
Specifications are Point of Measurement Dependent
Catalog specifications and specifications in this manual are measured from the center of the
carriage, 38 mm above the carriage surface. All measurements taken at any other location may
deviate from these values.

404LXR Series Technical Data
The useful life of a linear table at full catalog specifications is dependent on the forces acting upon it. These forces include both
static components resulting from payload weight, and dynamic components due to acceleration/deceleration of the load. In
multi-axes applications, the primary positioner at the bottom of the stack usually establishes the load limits for the combined
axes. When determining load/life, it is critical to include the weight of all positioning elements that contribute to the load
supported by the primary axis. The life/load charts are used to establish the table life relative to the applied loads.

Table Load Chart
The “Table Load” chart is
intended to provide a rough-
cut evaluation “life/load”
characteristics of the carriage
support bearings. This curve
is based on the applied load
being centered on the
carriage, normal to the
carriage mounting surface.
Bearing Load Chart
The “Bearing Load” chart
is to be used in conjunction
with the corresponding
formulas on the following
pages to establish the life/load
for each bearing (4 per table).
Several dimensions and the
load geometry are required
for these computations. The
dimensions are referenced
below.

404LXR Series Product Manual Chapter 2 - 404LXR Series Table Specifications
14
Note: 55 (N) continuous is the life rating if the table is operated with a motor thrust force of 55 Newtons
(RMS). The reason that continuous motor force effects bearing life is due to forces applied to the bearing
caused by thermal expansion of the carriage. The 28 (N) rating is the life if only 28 Newtons (RMS) is used.

Life for each bearing needs to be evaluated
independently. For bearings with a side load,
refer to the combined equivalent loading factors

Clean Room Preparation
404LXR tables with clean room preparation were tested in Parker’s vertical laminar flow work station which
utilizes ULPA filters to produce an environment having a cleanliness of class 1 prior to testing. Tables were
tested in a variety of orientations with sampling both below the table and at the carriage mounting surface.
Laminar flow rate is 0.65 inches W.C.
