［Application］
Can be used to hold down drawings, rules and paper
patterns. The holders with a tapped hole on the back
can be used widely by installing them on jigs. Can be
incorporated in press dies. Can hold workpieces during
wire cutting.
［Features］
●Six types of specifications; OD tolerance, plating,
painting, peripheral knurling, stainless steel spec.
and heat-resistance spec. are available for selection
according to applications.
●By matching the OD “h” tolerance, the holders can
be incorporated in dies.
●A tapped hole on the back makes the holders useful
in various applications.
The holding power drops as body temperature rises. The following types
are available. The original holding power returns to the original level
when the temperature drops to normal temperature.
■Type A (Alnico magnet used)
Superior in terms of temperature. The holding power as high as 85% can
be maintained at 350℃ when the holding power at 20℃ is 100%. This
type can be used up to 400℃ intermittently for a short period of time.
■Type B (Samarium-cobalt type rare earth magnet used)
The holding power drops to about 95% at 100℃ and to about 85% at
200℃ when the holding power at 20℃ is 100%. For continuous use,
the upper limit is 150℃ and for intermittent use for a short period of
time, this type may be used up to 200℃.
■Type C (Neodymium rare earth magnet used)
The holding power drops to about 85% at 50℃ and to about 70% at
100℃ when the holding power at 20℃ is 100%. The upper limit for
continuous use is 100℃.
