/ Precision Measuring Tools / Gage Blocks / Standard Reference Bars / RBC 37. * Not actual product image RBC 37. Standard Reference Bar #(--edpnumber)# Standard Reference Bars 37" Reference Bar - With Channel Design These Standard Reference Bars are invaluable for use in checking table movement of machine tools, accuracy of vernier height gages, surface plate transfer measurement, and for final inspection of precision machine tools and coordinate measuring machines. The "channel design" places additional measuring pads at appropriate points over the length of the bar as reference points for x, y or z axis measurements. Channel design permits use of the bar on its base (vertical), or on its back, or either side (horizontal). The alternating gage block jaws and spacer blocks are permanently wrung and fastened together to form 1" increments. A special bushing arrangement allows the master stack to conform to thermal conditions prevailing during use, thus providing a true master even under less than perfect laboratory conditions. Mating surfaces are treated during assembly to prevent corrosion. Non-standard lengths and measuring increments are available on special order.
