ST Series Stainless Steel Miniature Guides
Stainless miniature guides from 3 mm rail width, in three block lengths.
ST-C / ST-L / ST-SOverview
ST miniature guides are built from stainless steel for humid, washdown and clean environments. The profile starts at 3 mm rail width for the smallest slides and runs to 20 mm. Blocks come in C, L and S lengths, so the same rail can carry compact or long carriages. Rails are cut and drilled to order.
Key Features
- Stainless rail, block and balls
- Rail widths from 3 mm to 20 mm
- C, L and S block lengths
