The Unimec Mechanical Screw Jacks XTP Series Sizes 204, 306, and 407 feature AISI 316 as standard for all components, including the threaded spindles, covers, bushings, casings, end fittings and motor flanges. The only exception is the worm screw, which undergoes a Niploy treatment in case of any protrusions. The X Series can be applied in marine environments where oxidising is a problem. All the remaining sizes can be supplied in AISI 304 or 316 stainless steel upon special request. The Unimec X Series stainless steel screw jacks from HMA Flow & Industrial are ideal for applications where a permanent resistance to oxidising is a requirement.
