Product Description

What this part is

A Fafnir 2MM219WI-SUL super-precision single-row angular contact ball bearing. Bore 95 mm, outside diameter 170 mm, width 32 mm. Open on both faces, universally ground. The ISO envelope is the 7219 medium series.

Decoding the designation

2MM — 15° contact angle in the Fafnir scheme; the MM prefix carries the P4S build219 — no leading 9, so this is the ISO 72 medium series, 95 mm bore: ISO equivalent 7219-CWI — super-precision spindle bearing seriesSU — single universally groundL — light preload

What these specs mean in practice

The 72 medium series carries a heavier section than the 70 light series at the same bore, trading speed ceiling for load capacity. A 15° contact angle favours speed and radial stiffness over thrust. Universal grinding means any two rings of this designation stack back-to-back, face-to-face or in tandem and reach the stated light preload without shims.

Quantity and configuration

Single universally ground bearing. 1 Pc per sale unit.

Fitting notes

Thrust is carried in one direction only, so the bearing runs against an opposing bearing or a housing shoulder. The wide outer-ring land is the thrust face and its orientation sets the arrangement.

Interchange guidance

Interchanges with RHP 7219CTRSULP4, NSK 7219CTRSULP4, FAG B7219-C-T-P4S-UL and SKF 7219 CD/P4ADGB at 15°, super precision, light preload. The 25° 3MM219WI and SNFA E295-7CE3 share the envelope at a different contact angle and are related sizes rather than interchanges.
