Overall Width: 33 mm (1.299 in) per bearing. Total Width: 66 mm across the mounted pair. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Preload: Light. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. The ISO size equivalent is 7026. Country of Origin: United States.

Decoding the designation

2MM — 15° contact angle, ABEC 7 / ISO P4 tolerance class.

9126 — Fafnir’s number for the ISO 7026 envelope, 130 x 200 x 33 mm.

WI — low shoulder on both rings, the duplex grinding form.

CR — one-piece machined phenolic cage.

DUL — duplex, universally ground, light preload. Two single-row bearings ground as a matched set.

What these specs mean in practice

A 15° contact angle keeps the load path close to the radial plane. That is the angle used on machine tool spindles running at speed under a predominantly radial cutting load.

Phenolic is a light, self-lubricating cage material and runs quiet at spindle speeds. It is the standard cage across the Fafnir 9100WI super-precision range.

ABEC 7 / P4 fixes bore, outside diameter, width and running accuracy to ISO P4 tolerances.

Quantity and configuration

Unit Quantity: 2 Pcs. The two bearings are a factory-matched duplex set. Universal grinding lets the pair stack back-to-back (DB), face-to-face (DF) or in tandem (DT), and the ground ring faces carry the light preload. The set is preload-set.

Mounting data

Bore Diameter: 130 mm. Outside Diameter: 200 mm. Overall Width: 33 mm per bearing, 66 mm for the pair stacked. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1 per bearing. Snap ring: No. Harmonization Code: 8482.10.50.

Interchange guidance

Same envelope, 15° contact angle and super-precision class: SKF 7026 CD/P4ADGA, FAG B7026-C-T-P4S-UL, NSK 7026CTRDULP4, NTN 7026CDB/GLP4, RHP 7026CTDULP4, Koyo 7026CDB, SNR 7026CVDUJ74. The current Timken catalogue designation is 2MM9126WICRDUL.
