The HydraRib bearing is a tapered roller design available in any class of precision to maintain optimum spindle system preload. The HydraRib has a floating outer race rib, positioned by hydraulic or pneumatic pressure, and is in contact with the large roller ends, instead of the usual fixed inner race rib. This retains system stiffness while allowing for thermal expansion. The HydraRib bearing's floating rib design allows it to compensate for thermal growth variations, while maintaining the optimum setting and accuracy for a variety of speeds and loads.
·Precision metric bearing available in any precision class.
• Floating outer ring rib maintains preload using fluid pressure.
• Unique design allows for thermal expansion of spindle while maintaining desired preload.
• Ideal choice for floating position bearing set. • Only minor modifications needed on existing spindles to install.
• Speed ratings for Hydra-Rib and Spring-Rib bearings are significantly higher than standard ribbed-cone designs. Consult the Engineering Section for greater detail, or contact your Timken representative.|
