    Kerk LRS Linear Guides optional Black Ice TFE coating.

    The lead screw is made from 303 stainless steel and can be configured with optional Black Ice TFE coating for durable and permanent lubrication. The LRS Linear Rail system comes standard with a general purpose lead screw nut, but for extreme control, the system can be configured with an optional Kerk CMP or WDG precision anti-backlash nut.

    303 Stainless Steel lead-screws and guide rails are corrosion resistant, non-magnetic, and compatible with many demanding processes.

    Black Ice® TFE s a maintenance free, hard coating that offers exceptional durability in all types of environments, with virtually any type of polymer nut. Black Ice TFE coating remains on the screw, offering a low friction surface upon which the nut travels. Rather than acting as a dry lubricant, Black Ice TFE is an anti-friction coating whose surface properties displace the metal to which it is applied. Though it is not intended for use with metal or glass fiber reinforced nuts, Black Ice TFE is bonded securely to the screw’s surface and can withstand abrasion from contamination, rigid polymer systems, fluid impingement and wash down applications. Black Ice TFE can be used in the presence of more aggressive environment conditions, or anywhere reduced friction and a permanent coating is desired.
