Rundlauflagen

Rundlauflagen, also known as linear recirculating ball bearings or linear ball slides, are mechanical guidance systems designed for linear motion. They utilize rolling elements, typically balls, housed within a cage that recirculates them. This recirculating design allows for continuous motion along a shaft or rail. The core components consist of a shaft or rail, a bearing block containing the recirculating balls, and a cage to guide the balls.

The principle of operation involves the balls rolling between the bearing surfaces of the shaft/rail and the bearing block. As the block moves, the balls are guided by the cage, returning to the starting point of their rolling path within the block. This continuous recirculation minimizes friction and wear, enabling smooth and precise linear movement with high load-carrying capacity.

Rundlauflagen are characterized by their low friction, high stiffness, and excellent repeatability. They are suitable for applications requiring precise positioning and high operational speeds. Common applications include machine tools, automation equipment, measuring instruments, and general industrial machinery where linear guidance is essential. They are available in various configurations, including open and closed designs, and can be integrated into compact assemblies. Maintenance typically involves lubrication to ensure optimal performance and longevity.
