SKU 9055 is an N35SH high-temperature neodymium ring magnet measuring 1/4 in. OD × 1/8 in. ID × 0.1 in. thick. Its SH-grade material is specified for elevated-temperature applications compared with standard N-grade NdFeB, while the center bore provides clearance for compact mechanical and electromechanical assemblies.
This stock ring is axially magnetized through its thickness. The poles are on the flat annular faces; the ring geometry should not be confused with true radial magnetization.

High-Temperature Ring Magnet Selection
Operating-temperature capability depends on more than the grade suffix alone. Magnet geometry, permeance coefficient, opposing fields and the complete magnetic circuit affect irreversible-demagnetization margin. For elevated-temperature designs, evaluate the actual operating point rather than using maximum-temperature data as a universal guarantee.
Compare additional stock sizes in the Ring Magnets catalog, review the Magnet Temperature Derating Calculator, or use the Magnet RFQ Builder for custom ring geometry, higher-temperature grades or specialized magnetization.
Listed pull force is a comparison value rather than a safe working load. Target steel thickness, air gaps, coatings, alignment and loading direction affect actual retention. Test the complete assembly under its intended conditions before production. Protect the brittle magnet from impact and avoid an interference fit that could chip or crack it.
Use the pull-force calculator for preliminary geometry comparisons, then validate the actual ring assembly.
