• 120, 65 and 40mm footprints
• Lockable

In many manufacturing applications weight is at a premium. Aluminum stages are used when weight needs to be minimized. In order to maintain the required accuracy precision crossed-roller bearings are mounted into the machined aluminum.

Three sizes cover most applications. The 120mm stages are best for heavy load applications. While the 65mm size is ideal for most general equipment applications. A 40mm range provides more compact mounting for use in instruments where space is at a premium. All sizes have inch or metric hole patterns which enable them to be built as compactly as possible. Travel is listed for each stage but can be extended slightly beyond this range if necessary.

• Lightweight
• Precision ball bearings
• Straightness of travel <3microns
• 65 and 25mm footprint
• 1/4-20 (M6) hole pattern
• Horizontal and vertical motion
• Micrometer driven
• Lockable

Aluminum stages are best used when weight must be minimized and the stability of steel is not needed. In order to maintain the required accuracy ball bearings are factory pre-loaded by four equally spaced stainless steel rods that are machined into the aluminum stage to ensure precision and load capacity.

Two sizes are offered. The 65mm size is suitable for most laboratory applications having a two inch square 1/4-20 hole pattern for mounting to industry standard bases. The 25mm size is compatible with the mini-system previously described (page 272). It has a metric (M2) hole pattern on 10mm centers and provides 6mm of travel.

• Travel up to 120mm
• Lead screw driven
• Crossed roller bearings for high load capacity

For applications that require long manual travel, these lead screw driven stages are the solution. They are constructed from aluminum using crossed roller bearings to provide high load capacity. Each stage is driven through use of a hand crank attached directly to the lead screw. These long travel stages are available as 200mm and 300mm footprints in X and XY configurations. The 200mm version has 100mm of travel and the 300mm footprint has 120mm of travel. All stages have convenient 1/4-20 tapped holes on inch centers or M6 tapped holes on 25mm centers for metric versions.
