ISO14001 Certified Sintered Neodymium Magnet for Industrial Motors

Meta Title: ISO 14001 NdFeB Arc Magnets – Sintered Neodymium Iron Boron | Industrial Grade
Meta Description: Precision arc-segment sintered neodymium magnets, ISO 14001 certified, for motors, generators, and actuators. N35–N52SH grades, ±0.05 mm tolerance, Ni-Cu-Ni or epoxy coating. Instant quote & 7-day prototypes.

  1. Product Overview
    When your motor or generator demands maximum flux density in a curved geometry, our ISO 14001 certified sintered neodymium iron boron (NdFeB) arc magnets deliver. Produced in an environmentally-managed facility, every arc segment meets tight ±0.05 mm tolerances and is 100 % inspected for magnetic uniformity—ideal for servo motors, BLDC motors, wind-turbine generators, and magnetic couplings.
