9663 – N35 Ring Magnet 15.8mm OD x 6.5mm ID x 5mm

SKU 9663 is an N35 neodymium ring magnet measuring 15.80 mm OD × 6.50 mm ID × 5 mm thick. Axially magnetized through the 5 mm thickness, this metric ring provides a substantial annular cross-section around a 6.5 mm center bore for engineers and procurement teams balancing clearance with magnetic holding capability.

Ring magnet design notes

The north and south poles are on the two flat annular faces; this stock part is not a true radially magnetized ring. The 6.5 mm bore can provide clearance for a shaft, sleeve, fastener, or locating feature while the remaining annular cross-section forms the magnetic circuit.

The listed pull force is a reference value under controlled conditions. Air gap, target steel, contact area, surface finish, temperature, and load direction all affect installed performance.
