High Temperature Linear Guides are required for harsh environments. Special materials complemented with special surface treatments are often needed for demanding high temperature environments. The more we know about your application the better we can choose the materials and processes best suited for the intended environment. Key factors will be payload, motion move profile, duty cycle, and time at temperature. A long time (i.e., greater than 2 hours) at temperature above 400 degrees F will begin to temper back standard hardened bearing steel. We have products operating in ovens at 700 degrees Centigrade! Allow us to help you make the right material choice!
Special Surface Treatment
Metal tends to oxidize quickly when continuously exposed to elevated or high temperatures. We can prevent this by running these products through a secondary process that creates a highly rust-resistant surface layer. The process called a Low Temperature Black Chrome treatment is a new generation surface property modification technology.
Originally developed and known as "Raydent" treatment in Japan. Done by an electrochemical reaction at a temperature below 0 deg C. An alloy-like diffusion layer (about 1 micron) in the bulk of the metallic material is created. The Raydent coating and the base metal are completely integrated, so the coating is semi-permanent and will not separate (exfoliate).
Block & Rail Special Treatment
Finished machined and heat treated bearing steel metal blocks are treated via the special process prior to moving into final assembly.
Rails are also routed through the same process since they too are typically open and exposed to the high temperature environment.
Billet Machined Aluminum End Cap
The standard polymer end caps are replaced with billet machined aluminum end caps. It's important to remove all polymer and rubber pieces since these are the limiting factor in most block assemblies.
Caps have intricate internal routing paths to allow the balls to smoothly transition back into the block for re-circulation.
