N35-N52 Neodymium Permanent Magnets with Maximum Magnetization Direction Less than 60mm

N52 D40x100mm Neodymium Rod Magnets :
Dear Manufacturer
I will need 2000 items sintered NdFeB rod magnets 40 mm diameter/ 100 mm length N52 made.
Magnetism two far points, not round side….
16 items; sintered NdFeB permanent magnets, 160 mm diameter, 60 mm height ring shape
Magnetism two circle sides not round side…. Middle of magnets I need 80 mm holes with cone for screw.
Let me know what maximum Gauss you can make and prices…

Neodymium Magnet Manufacturer China Rare Earth Magnet Limited:
Do you mean that you need 2000pcs N52 D40x100mm rod magnets, magnetized through axial as the following drawing?



Please kindly confirm, because for N52 magnets are made of very brittle material. The maximum magnetization direction producible is about 60mm.
And for the second type with cone for screw, could you provide a drawing?

N45 Magnet:
Okay, make it N45 not N52.... I need 100mm long but strong magnets....

N35-N52 Permanent Magnet Manufacturer China Rare Earth Magnet Limited:
Sorry if I mislead you.
When I mentioned the maximum magnetization direction producible is about 60mm.
I mean all neodymium magnets especially Grade N52.
The higher the grade is, the more brittle it gets.
Please kindly reconsider the dimensions.

N52 Magnet:
OK, let me know all the details of D40mm / H58mm N52 rod magnets...

Quantity & Magnetization:
What will be the quantity and magnetization direction for the D40mm / H58mm N52 magnet?

Quantity:
2000items.
