FAG32222ATapered Roller Bearing – 110 mm Bore, 200 mm OD, 56 mm Width, Separable Cone and Cup, 322 Series

Product Description

What this part is

FAG 32222-A metric tapered roller bearing, cone and cup, to DIN 720. The cone and cup separate, so each ring can be fitted with its own interference and the bearing set by axial adjustment. Bore Diameter: 110 mm. Outside Diameter: 200 mm. Total Width: 56 mm. Inner ring width: 53 mm. Outer ring width: 46 mm. Dynamic Load Rating: 410,000 N. Static Load Rating: 590,000 N. Limiting Speed: 3,450 rpm. Reference Speed: 2,410 rpm. Rolling Elements: Tapered Roller. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Item Weight: 7.22 kg (15.92 lb). Bearing Material: Chrome steel. Unit Quantity: 1 Pc. Series: 322. Base Number: 32222.

Decoding the designation

322 — ISO dimension series 322, the steep-angle wide section of the metric tapered roller range. The steeper cup angle raises thrust capacity against the 302 and 303 series on the same bore.

22 — bore code; 110 mm bore.

A — the current Schaeffler design generation for this size.

T3FC110 — the comparative designation for this bearing under ISO 10317 and ISO 355.

What these specs mean in practice

Static Load Rating: 590,000 N against a Dynamic Load Rating of 410,000 N. On tapered roller bearings the static figure sits above the dynamic throughout the range, because line contact along the full roller length carries an enormous standing load.

Calculation factors: e = 0.42, Y = 1.43, Y0 = 0.79. Where the axial to radial load ratio exceeds 0.42, the axial component enters the equivalent load calculation with the Y factor of 1.43. Those are the figures a bearing life calculation needs and they are specific to the 322 series angle.

Fatigue load limit: 67,000 N. Limiting Speed: 3,450 rpm is the mechanical ceiling; Reference Speed: 2,410 rpm is the thermally referenced figure.

Operating temperature range: −30 °C to 120 °C.

Mounting data

Shaft shoulder diameter: 122 mm minimum to 126 mm maximum. Housing shoulder diameter: 170 mm and 190 mm minimum, 188 mm maximum. Guidance rib diameter of the inner ring: 153.5 mm. Distance between the apexes of the pressure cones: 46 mm. Maximum fillet radius of the housing: 2.5 mm. Maximum recess radius: 3 mm. Minimum chamfer dimension: 3 mm on the inner ring back face, 2.5 mm on the outer ring back face. Minimum axial space: 6 mm and 10 mm.

Quantity and configuration

Unit Quantity: 1 Pc. Complete bearing: cone with rollers and cage, plus the matching cup.

Interchange guidance

32222 is a DIN 720 / ISO standard number and every major maker builds it to the same 110 x 200 x 56 mm envelope with the same 322-series contact geometry, so the cross-references below are direct interchanges. Designation variants: 32222-A, 32222A, 32222 A, T3FC110.
