Fiber Optic Tools and Supplies BUY | SELL | TRADE ebay@surpluseq.com SurplusEQ Product ID: 253870 Our Description The CR4500 Series Positioner is 2.62in in width with a traveling length of about 25mm. It has Imperial mounting with 7 #10-32 threaded mounting holes on 2" diameters B.C. There are two custom drilled holes (best seen in the picture), one in the center with a 8mm Diameter and another where one of the #10-32 threaded hole was (also with a 8mm diameter). Neither of the custom drilled holes are threaded. It does not include a micrometer, but it does have lockable positioning. The item is in very good condition. Manufacturer Description The crossed roller bearing system is composed of two rows of rollers. Each roller is alternately crossed at 90° with the next and captured in “V” grooves, located on the base and top. Since rollers provide a larger (line) contact surface than ball bearings, a crossed roller positioner has higher load carrying capability than a ball bearing positioner of comparable size. These changes also significantly increase the stiffness by increasing the contact area of each bearing. Crossed roller positioners are preloaded to eliminate any side play and to provide a uniform coefficient of friction. The crossed roller bearing system is composed of two rows of rollers.
