Linear ball bearing:The linear ball bearings feature fixing bore 0.3 mm below the middle line and 0.5 mm fixing bore. The load capacities are valid only if hardened (min 670 HV) and ground shaft raceways are used. The bearings are available in various series and in special series as well on request.
Linear ball bearing:Linear Bushing systems are a combination of a Ball Bushing
(s) and LM shaft to perform infinite straight motion guiding. The permissible load rating of bushing systems are not as great as SBC profiled rail systems however they are a good, lower cost alternative where precise linear guidance is desired in light load applications.
