Fafnir 2MM/3MM215WI TUL matched triple set of super-precision angular contact ball bearings. Bore Diameter: 75 mm. Outside Diameter: 130 mm. Overall Width: 25 mm per bearing. Precision Class: ABEC 7 / P4. Unit Quantity: 3 Pcs. The envelope is the ISO 7215 size.
2MM — Timken/Fafnir super-precision class at a 15° contact angle, ISO P4 / ABEC 7.
3MM — the same super-precision class at a 25° contact angle.
215 — the ISO 7215 size: 75 mm bore, 130 mm outside diameter, 25 mm width.
WI — low shoulder on both rings, the ground duplex form.
TUL — triple universally ground, light preload. The three bearings are ground as one matched stack.
Contact Angle: 15° and 25°. Two bearings carry the 15° angle and one carries 25°. A 15° angle favours speed and radial stiffness; 25° carries more axial load.
Preload: Light. Mounting Arrangement: Universal. Rolling Elements: Ball. Number Of Rows: 1 per bearing. Bore Type: Straight. Closure Type: Open. Bearing Material: Steel. Series: 7200.
Unit Quantity: 3 Pcs. Arrangement / Configuration: matched triple set, two bearings at 15° and one at 25°, ground for light preload.
The 75 x 130 x 25 mm envelope is the ISO 7215 size, carried by SKF, FAG, NSK, NTN, RHP, Koyo, MRC and SNR under the same 7215 base number. Those crosses are on the single-bearing envelope; this listing is a factory-matched three-bearing stack.
