Crossed Roller
Crossed roller bearing stages offer all the advantages of ball & rail bearings with higher load capacity and stiffness. The increased load and stiffness are a direct result of replacing the point contact of the ball with a line contact of the roller. Crossed roller bearings are externally loaded in the same manner as ball & rail bearings but require more attention to detail during the assembly process. This lengthened assembly process, plus the added manufacturing time of the ground rollers and guideways, is the reason for the higher cost of these precision stages. Crossed roller stages are ideal for applications requiring high load, high stiffness, and precision bidirectional straightness, such as fiber alignment, semiconductor probing, and cellular research. These stages are available in both motorized and manual versions.
