Linear system can handle welding spatter and chips

The sturdy CKK compact module with the "Resist" cover is unsusceptible to welding spatter and dry chip impact.

New in the product portfolio from Bosch Rexroth: the sturdy CKK linear motion axis with the "Resist" cover

Rexroth has now put the CKK compact module with the "Resist" cover, originally developed specifically for a European automobile manufacturer, into the linear motion technology standard product range. The ready-to-install linear motion axis is particularly suited for handling components during welding and dry chip impact. The new cover is free from paint-wetting impairment substances, PWIS. The connection dimensions, configuration and delivery times of the new series-produced variant correspond to the standard versions.

Welding applications always produce welding spatter, which can also hit the handling axes. It can also enter the interior of unprotected assemblies and lead to increased wear and premature breakdown. Therefore, the handling axes are often encapsulated, which causes high additional costs and poor accessibility. The CKK compact module with the "Resist" cover is different. Several hundred examples have been proving their worth for years in the body shop of a European automobile manufacturer. An additional plate with a toothed sealing profile prevents welding spatter and chips from entering the interior of the compact module. The exchangeable sealing profile consists of FKM material with a short-term temperature stability of up to 300 °C. The sealing profiles are silicone-free and therefore conform to PWIS. This is an important requirement of the automobile industry in order to guarantee the proper coating of components.

Apart from a slightly increased total height due to the additional profile, the CKK with "Resist" cover offered in sizes -110, -145 and -200 corresponds to the standard versions of the compact module with ball screw drive. It has an application-oriented long carriage with connection plate. The connection dimensions of the profile body and the carriage with connection plate are identical to those of the series. Thanks to the positive-locking connection technology with centering rings, no major adjustments are necessary during mounting and start-up.

The compact modules simplify motor attachment due to the locating feature and fastening thread. Design engineers configure the sturdy variants as usual with the online tools from Rexroth and maintain the corresponding CAD data. Adjustable switches across the entire travel path reinforce the high positioning accuracy and repeatability from the ball screw drive with zero-backlash nut system. The delivery times correspond to those of the standard compact module.

The CKK compact module with the "Resist" cover also fits into the one-point lubrication concept used in the automobile industry, for both liquid grease and oil. The sturdy linear motion systems are suitable for all handling applications relating to dry machining and welding of vehicles.
