Kerk BGS Linear Guides have Black Ice® TFE on all critical surfaces.
At the heart of the BGS Linear Rail system is a Haydon® hybrid linear actuator with a precision 303 stainless steel lead-screw. The lead screw drives a machined aluminum carriage mounted to a precision stainless steel ball slide resulting in a rigid, smooth operating motion system. The screw is coated with Black Ice® TFE coating providing a permanent wear resistant dry lubrication.
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.
