Complete Model Code
Select US / USA variant and size, effective stroke and mounting geometry. Catalog options are series-specific (C1 / T1 / P); confirm the complete configuration with UVT.
Mounting & Lubrication
US is supplied without grease. Provide appropriate lubrication and external travel limits; do not use maximum stroke as normal operating travel. No standard seals or internal mechanical stop.
Special materials, cleanroom, vacuum and dry-running suitability require individual review.
