Bushings and Bearings Handle High Loads
Each Super Smart Ball BushingT bearing uses precision ground balls manufactured to the highest quality standards for roundness and sphericity
Ondrives is offering a range of Super SmartT bushings and bearings from the linear motion series of its mechanical drive components catalogue. Super SmartT offers twice the load capacity or eight times the travel life of the industry standard, whilst being physically smaller in size than conventional linear bearings.
The load carrying capacity of the Super Smart Ball BushingT is the combination of four hardened bearing quality steel components.
The first component is the steel outer ring, which allows the bearing to maintain its diametrical fit-up even when installed in a housing that is slightly out-of-round.The ring design also allows for bearing adjustment and the removal of diametrical clearance.The second component is the precision super finished double-track bearing plate that provides twice the load capacity and features universal self-alignment.The third component is the rolling element.
Each Super Smart Ball BushingT bearing uses precision ground balls manufactured to the highest quality standards for roundness and sphericity.The result is maximum load capacity, travel life and performance.The last component is the 60 Case LinearRaceT shaft that acts as the inner race to the Super Smart Ball BushingT bearing.
Each 60 Case LinearRaceT is manufactured to the highest quality standards for roundness, straightness, surface finish and hardness. Roundness is held under 4mm; straightness to 0.05mm per 300mm; surface finish under 0.30um and hardness between 60-65 HRC.
The combination of inner and outer race or 60 Case LinearRaceT and Super Smart Ball BushingT bearing provides the basis for the RoundRail AdvantageT.
The RoundRail AdvantageT is the inherent ability of a Super Smart Ball BushingT bearing system to accommodate torsional misalignment (caused by inaccuracies in carriage or base machining or by machine deflection) with little increase in stress to bearing components.
Installation time and cost are minimised and system performance is maximised.
