Alnico deep pot magnets (zinc plated)–Precision Outer Diameter Versions
These Alnico deep pot magnets have a precision ground outer diameter for press fitting into precision milled holes.Like the standard alnico deep pot magnets, they are blind ended deep pot magnets.
The precision ground alnico deep pot magnet comprises an Alnico 5 magnet surrounded by a brass retaining ring spacer which are both inside a zinc plated mild steel body ("cup”) that is blind ended at the rear (no thread or tapped hole at the back). The magnetic pole face is ground to a smooth finish. The outer diameter is ground to a H6 tolerance, making it ideal for press fitting within milled-out holes.
Alnico Magnet with Good Corrosion Resistance
The precision ground outer diameter alnico deep pot magnet, with its zinc plated steel body, has good corrosion resistance and allows excellent performance in many oils.
The alnico deep pot magnet with precision ground OD is used at ambient temperatures and are great for high temperature use. They are recommended for use in temperatures up to +220 degrees C(+428 Fahrenheit), and can potentially be used at temperatures up to +400°C(+752 Fahrenheit). When being operated at temperatures above +200 °C,the materials making up the pot magnet may start to become loose due to expansion coefficients of the different materials, so it is only recommended for use with caution above +200 °C.
Alnico has the best temperature coefficient of magnetic induction for any magnetic material so only reduces its magnetic performance slightly as the magnet heats up. This allows the alnico deep pot magnet with a precision ground outer diameter to keep performing very well as the pot magnet heats up (the Br falls the least with rising temperature when using alnico magnetic material).
Precision Ground Alnico Deep Pot Magnet for Press-Fit Applications
This type of magnet is perfect for press-fit applications, having its H6 tolerance outer diameter. The precision ground alnico deep pot magnet is used in many applications, including clamping,tooling/ fixturing and general clamping. The 'deep' pot design of the alnico deep pot magnet provides stability of magnetic performance and excellent thermal capability
It is possible to produce customised versions of this magnet. For example, the mild steel casing can be chrome or nickel plated. Also, the rear of the pot magnet could have a tapped hole or a thread included – please contact us for prices and lead times (minimum order quantities may apply).
