Bahr Modultechnik offers its Linear axes also with hygienic stainless steel coating on. In many production areas of the pharmaceutical and food industry, the process-related machine and plant components must be made from materials that are easy to clean, scratch and abrasion resistant and that do not provide a primer for bacteria. Stainless steel meets these requirements optimally.
However, since a corresponding sheathing of positioning axes difficult due to their geometry, there has been no satisfactory, economical solution on the market. Also, the attempt by manufacturers to stick the stainless steel sheets on the profiles, in the literal sense of not sustainable: Different thermal expansion of the profiles and the glued sheets strained the contact points and led to early detachment. The new approach is based on the development of a special process to encase the aluminum guide profiles of its linear axes with stainless steel sheet.
In the patented process, a machine specially designed for this purpose bends the stainless steel sheets precisely around the profiles. The sheet edges are bent around the profile wall of the carriage guide slot and locked in undercuts in the interior of the profile with reliable interference fit.
