Application
You can use it to hold down drawings, rules, and paper patterns.
The models with tapped holes 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 may drop when the holder is worked on additionally. In particular, additional work in the radial direction has a large influence on the holding power and therefore, must be limited to a minimum necessary scope.

The upper limit of working temperature
The holding power drops as the 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.
■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, 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℃.
