Product Description

What this part is

Angular contact ball bearing, 140 mm bore, 210 mm outside diameter, 33 mm width. Duplex pair, ground for face-to-face or back-to-back mounting.

Decoding the designation

2MM — Fafnir 15° contact angle series, ABEC 7 / ISO P4 precision.

9128 — Fafnir’s size code for the 140 x 210 x 33 mm envelope, cross-referenced on the carton as 7028-C.

WI — low-shoulder duplex form, ground for pairing.

DUM — duplex universal ground, medium preload.

What these specs mean in practice

Bore Diameter: 140 mm. Outside Diameter: 210 mm. Overall Width: 33 mm. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Closure Type: Open. Preload: Medium.

The duplex-ground faces set a medium preload once the pair is mounted together, holding tighter axial location than a light-preload pair under equivalent load.
