SFERAX RSF 20 A
8010.000020.20
This linear unit consists of a housing/ball bearing RSF and a shaft ASF. It is different from the other SFERAX-systems. The RSF is a super compact rectangular ball bearing. Its guiding slide ASF also serves as support thanks to its ground flat surface, and can be fixed directly with blind threaded holes (ASF-M) or counterbored through holes (ASF-V).
Application
Through its great rigidity, this unit can be used in various engineering design situations as well as in the machine tool industry. High load carrying capacity, minimal space requirement, good heat resistance are further advantages.
