Threaded NdFeB Ring Countersunk Magnet/round magnet/sintered magnet/cheap magnet
1.Shallow pot magnets are low profile for applications where height is limited.
2.They have a clearance hole through and a countersunk on the magnetic face to accept a countersunk screw.
3.The range of Shallow Pot Magnets is wide and shallow, the north and south poles are on the same plane.
4.Because the gap between the poles is narrow, they have a shallow flux field, these magnets are ideal for limpet type gripping applications.
5.Each magnet in the range is manufactured with a standard M6 thread for building into jigs and fixtures, fitted with a J bolt.
6.Surface can be red painted, or coated with nickel, zinc or Chrome.
7.ring holding magnets can be fixed onto or sunken into steel surfaces without any loss of performance.

The ring shape allows smaller mechanical tolerance compared to Segment Magnets.
Motor assembly is made much easier; installation of one or more rings versus gluing arcs into place.
Currently attainable qualities: 35H, 40H, 45H, 38M, 35SH, 38SH, 42SH, 35UH, 40UH.
Radial sintering may prevent so-called weak spots.
Homogeneous flux of the poles.
Uniformity of the magnetic field is significantly better than that of segment magnets.
Magnets are multi-poled – thus the ring does not compromise the magnetic properties.
Ring magnets offer substantial cost savings on assembling the rotor.
No additional rings or protecting cases are required for fixation.
Different types of magnetization are possible: diametrical, multipolar as well asso called “skewed” magnetization.
This ring provides high cost-effectiveness as well as better motor performance (as compared to the usual segment magnets).
The radial orientation results in a super strong magnet by virtue of superior metallurgy developed specifically to BE radially oriented.
