How to inquire
Send quantity, grade, coating, magnetization direction and a drawing or marked photo. If you are matching a sample, include the measured diameter or block size. Custom lots are quoted against the 10–15 day window published on the original product pages. N35 stock sizes, when available, ship sooner.
Questions buyers actually ask
Does rubber reduce pull?
It adds an air gap. You trade some holding force for grip and surface protection.
Heat and oil?
Rubber jackets are not for hot motor cavities. Use a metal pot or epoxy-coated magnet there.
