Ball slide positioning stages, micrometer tables, positioners

Ball Slide Positioning Stages

Isotech offers over 60 models of positioning slides.

Used for gaging and positioning light and medium loads, applications include measuring instruments and optical assemblies. Isotech positioners, built with the same rigorous manufacturing demands as our ball slide assemblies, offer the benefits of quality construction.

Spring loaded micrometer drives allow precise repeatable adjustments with low friction and zero backlash. (Micrometers available in inch or metric units.) Slides provide accuracy to .0005"/inch of travel and repeatability of .0001". Over 60 models, support load capacities to 60 lb. Our full line includes the subminiature series with the smallest commercially available positioner, the standard series, ideal for most gaging and positioning applications, and our heavy duty series providing high load capacities with the same high accuracy and repeatability.

Positioning slides can be stacked for multiaxis applications. Standard stacked units are available in XY and XYZ configurations. Preloaded positioning slides, fully assembled, arrive ready for your use.

Positioners are available in black anodized finish or other finishes on request.

Locking Methods

"Posi-Lock" feature consists of a steel shim and extended micrometer bracket secured by a screw mounted to the side of the stage carriage. This allows the user to positively lock the position of the carriage during use. Posi-Lock is standard on the model 99 and optional on all others. Specify "PL".

"Locking micrometer heads" are available to positively lock the micrometer setting. Not available for models 99, 101, 201, 301. Specify "L".

Ordering Nomenclature:

X = Single Axis
XY = Double Axis
XYZ = Triple Axis
P = Plain. No micrometer head, bracket or springs.
M = Metric micrometer head, 13 mm, 25 mm, or 50 mm; depending on model.
MM = Metric micrometer head and metric threaded mounting holes in carriage; metric C bore holes in base.
LO = Low profile Z axis; available in 300, 400, 450 and 750 (see outline drawings.)
L = Locking micrometer head.
PL = Posi-lock carriage lock.

Notes:

Loads in Z axis will extend springs if too heavy. Series 400, 500, 700, 1200, 2200 and 3200 have micrometer bracket reversed to prevent this and increase Z axis capacity.
Custom designs quoted on request.
Metric threaded mounting holes optional at no cost.
For standard inch size mtg. holes but metric micrometer head, (specify M).
P style (plain) are free floating slides without micrometer head, brackets or springs.
