According to JB/T10186 <Rolling bearings—Matched angular contact ball bearings—Specifications>, the end face convexity of angular contact ball bearings is
an important parameter in the assembly.
T69 series bearing convexity measuring instrument is the special instrument for measuring the end face convexity and concave amount (negative convexity) of
angular contact bearing, which is used to solve various matching problems of matched bearing. T6928 bearing convexity measuring instrument can meet the
measurement of the high precision doublehalf inner ring angular contact bearing convexity. The instrument has won the second prize for Mechanical industry
science and technology progress award.
●The measurement can be carried out under the condition of rated preload, and the value is reliable;
●Measuring load can be preset according to actual need.
●Stable and reliable with pneumatic load, no impact, high efficiency, simple operation; large load can adopt hydraulically loading.
●Spindle adopts air bearing and other precision bearings.
●Data can display and be printable.
●The instrument has reasonable design, advanced structure, good rigidity and accurate measurement.
