At the time of measurement of a tool, the joint corresponding to a tool is surely used.
3.2.1 SJ Joint
SJ joint is used for measurement of an electric driver.
In case joint is chosen, tolerance level is checked and it is cautious of exaggerated torque enough.
SJ joint (coiled-spring compression system)）
SJ50 （MAX 5 N・ｍ） SJ10K（MAX 1 N・ｍ） It attaches to CD100. Cap bolt portion H6
SJ10 （MAX 1 N・ｍ） It attaches to CD10. Cap bolt portion H5
The bolt omission prevention function was newly
carried in joint. By attaching an omission
prevention screw, if a bolt separates from a plinth, it
will race, and it does not decompose and trouble is
not caused to work. （However, when it continues
racing, a ridge may be worn out and torque value
may change.） Moreover, by wear, the metal fatigue,
etc. of a screw, where a spring is closed, it is left,
and a bolt may jump out with the pressure.
New joint which served also as the measure against dangerous prevention in that case. (PAT,P)
The cautions on use
The load more than the measurement range is not applied by any means.
It checks before use whether grease is attached to bolt and bearing.
After use is kept where a spring is surely loosened.
The number of times of an exchange standard is about 2500 times.
When the following condition comes out, use is stopped and new joint is used.
When there is wear of a bend and a ridge
When there is sound etc.
