In precision bearing system，the angular contact bearings are often used in conjunction group, in order to obtain high rigidity and high rotation accuracy, while applying rated pre-load, we also need the technical performance of matched bearings is consistent with each other as far as possible. The matching of bearing core & bearing cup end face convexity usually is taken by grinding the insulating spacer, but the operation is complicated and the actual pre-load is difficult to be controlled quantitatively, indicators it is difficult to get the performance of bearing system reliably, and the bearing lifetime will also be affected.
　　T69 series Bearing End-face Convex value measuring instrument which can measure the convex value and re-entrant of angular contact bearing end-face is designed to meet the requirement of war industry. It settles the matching problem of bearings in pairs successfully. T6928 bearing convex value measuring instrument is applicable to the measurement of high-precision split inner ring angular contact bearing. This instrument has won The State Technological Invention Award the second prize.

T6912	T6928

Feature

• The instrument can measure under rated pre-load. Reliable data.
• The load could be pre-set according to your need. Convenient use.
• Pneumatic loading, smoothly, reliably, no percussion, easy operation.
• The system uses air bearing or high-precision rolling bearing for spindle and realize the dynamic measurement. The results can be printed and saved.
• The whole system has reasonable design, advanced construction, high rigidity and accurate data. It is applicable to selecting matched bearings for bearing enterprise and matching host enterprise. At the same time, it also can be used as a reliable research and analysis tool in specialized laboratory. More important, it is the essential technical support of universal matching bearing matching bearing manufactory.
