PRECISION CROSSED ROLLER LINEAR STAGES
NEW series of motor ready linear positioning stages feature ALM
MADE IN USA, Precision Crossed Roller Linear Bearings. ALM Crossed Roller stages
are characterized by smooth, quiet, repeatable, frictionless motion while providing
flatness and straightline accuracy of 2 micron / 25mm travel. Torsional stiffness and
rigidity, zero sideplay in any attitude and minimal torque requirements make these stages
the designers choice for high precision linear positioning applications. Long life and
maintenance free operation make these stages ideal for cleanroom or difficult access
locations. ALM stages are available in aluminum or cast iron (stainless steel optional),
with ballscrews or leadscrews, and include english mounting holes (metric optional),
single piece NEMA frame motor mounts, and aluminum flexible coupling as standard.
The pictured 150mm wide x 50mm height custom stage was designed and
fabricated for a surface scan of a storage disk during manufacture. It is presently being
supplied to an OEM in Northern California for integration. This processing equipment is
then shipped to a Malaysian manufacturing site. This 50mm stroke stage features
"in-line" stainless steel crossed roller linear bearings, electroless nickel
plated 7075 aluminum alloy, teflon coated precision ground leadscrew, .1 micron resolution
non-contact linear encoder, 10,000 rpm air bearing spindle clamps in line within ½
micron, 1" length NEMA 17 frame motor mount, custom stainless steel servo coupling,
clean room compatible lifetime lubrication and stainless steel metric hardware throughout.
The stage performance specifications are as follows:
Parallelism of travel*: NTE 1 micron
* 2 planes
Straightline accuracy : NTE 1
micron
Positional accuracy : NTE 1/2 micron
Positional repeatability : NTE 1/2 micron
Pitch, Yaw, Roll error : NTE 5 arc seconds
Dynamic Noise Level : NTE 30 Db
ALM features the widest selection of accuracy grades, motor mounts,
materials, waycovers, finishes, limit switches and feedback options available, many
directly from stock. ALM stages can be supplied with custom mounting provisions, in
multi-axis configurations, with laser calibration certification, vacuum preparation, or
clean room certified. Can’t find a suitable standard product? ALM welcomes
application specific stage design and fabrication projects.
