Magnetic Wheel
磁力轮
AIC W-series magnetic wheels (FZW models) are cylindrical NdFeB drive and hold-down wheels for ferromagnetic surfaces. Each wheel combines a high-energy permanent magnet with a precision bore and standard keyway groove — bore diameter d is specified per model; fit tolerance class is H7 throughout the series.
The FZW catalogue spans nine models from FZW25 (φ25 mm, 55 N) to FZW160 (φ160 mm, 2940 N). Holding force is rated at room temperature on a 10 mm polished S235JR steel plate (DIN 10 025). All models are rated to 100 °C operating temperature.
The model table lists D, d, W, b, h, force, and weight for each FZW part number. H7 is the bore fit tolerance class and applies to every model — it is not a dimensional value in the table. Specify whether rubber coating is required and whether the counter-surface has a paint or other non-magnetic layer.
Key Features
FZW25 – FZW160 Range
Nine catalogue models, outer diameter φ25–φ160 mm — scale from compact inspection wheels to heavy drive units.
Catalogue Bore d + H7 Fit
Nominal bore diameter d from 8 to 50 mm per model; all bores machined to ISO H7 fit tolerance with standard keyway.
Up to 2940 N Adhesion
FZW160 delivers 2940 N holding force on 10 mm S235JR steel at room temperature.
100 °C Rated
All FZW models rated to 100 °C — suitable for industrial and automotive environments.
W-Series Dimension Drawing
D, d, W, b, and h are dimensional values — see the model table for each FZW part number. H7 is the ISO bore fit tolerance class and is common to the entire W series.

Holding forces measured at room temperature on a 10 mm polished S235JR steel plate (DIN 10 025). 1 kg ≈ 10 N. Column d is nominal bore diameter; H7 is the fit tolerance class for every model in this series. Values are for orientation; actual force depends on installation, temperature, and counter-surface material. Consult engineering for your application.

Answers to common questions about our magnets, customisation, ordering and shipping.
- What is a magnetic wheel (FZW)? +
- AIC W-series FZW magnetic wheels are cylindrical NdFeB drive/hold-down wheels for ferromagnetic surfaces, with a precision bore (nominal d, ISO H7 fit) and standard keyway — nine models from FZW25 (55 N) to FZW160 (2940 N).
- What is the difference between bore d and H7? +
- d is the nominal bore diameter (catalogue value per FZW model, 8–50 mm). H7 is the ISO bore fit tolerance class, common to the entire W series — the machined bore is finished to H7 tolerance with a standard keyway.
- What holding force do magnetic wheels provide? +
- Holding forces range from 55 N (FZW25) to 2940 N (FZW160), measured at room temperature on a 10 mm polished S235JR steel plate. Actual force depends on installation, temperature, and counter-surface material.
