Linear bearings for the miniature applications sector require a dif-ferent approach in the design of guidance systems. While normal criteria such as load carrying capacity, rigidity and operating life are important, the additional factor of size also applies for minia-ture bearing arrangements. However, simply “scaling down” thestandard sizes to smaller dimensions is not very successful intechnical terms. INA has therefore developed its four-row miniature linear ball bearing and guideway assembly KUME..C. For applications with a lower requirement for load carrying capacity, this high-performance guidance system is supplemented by a two-row guidance system.

Two-row linear recirculating ball bearing andguideway assemblies These units have moderate load carrying capacity,the moment load carrying capacity is moderate to high.Their modular construction allows the exchange ofguideways and carriages within one interchangeability and accuracy class. This gives simpler fitting of guidance systems, easier sourcing of replacement parts and allows very economical stockholding.The saddle plates and guideways are corrosion-resistant. Seals on the end faces of the carriages protect the rolling element system against contamination. The carriages are greased and can be relubricated. The guideways and carriages are also available in a wide version. Four-row linear recirculating ball bearing and guideway assemblies Four-row miniature linear recirculating ball bearing and guideway assemblies KUME..C are established, ready-to-fit guidance systems for unlimited stroke lengths. They have high load carrying capacity and rigidity.Due to the lubricant reservoir in the carriages, they are maintenance-free in many applications. Applications These linear recirculating guidance systems are particularly suitable for applications: in the microelectronics industry andrelated sectors in optical equipment in medical equipment in textile machinery that require high speeds andvery uniform running behaviour where particularly economical miniature guidance systems areneeded for moderate to high load requirements and moderate to high rigidity requirements.
