NachiFE32211JP4Tapered Roller Bearing Cone and Cup – 55 mm Bore, 100 mm OD, 26.75 mm Width, Flanged Outer Ring, P4 Precision

Product Description

What this part is: Nachi F-E-32211-J-P4 single-row metric tapered roller bearing, cone and cup together. Bore 55 mm, outside diameter 100 mm, overall width 26.75 mm. Series: 322. Flanged outer ring, straight bore, pressed steel cage. Precision Class: P4. Country of origin: Japan. Decoding the designation: 32211: single-row metric tapered roller bearing on a 55 mm bore, 322 dimension series — the steep-angle section, which carries a higher proportion of thrust than a 302 or 303 series bearing of the same bore. F: flange on the outer ring. E: high-capacity internal design. P4: precision class, giving radial and axial runout held to a few microns. J is an order-code position recorded here as a searchable part-number form. Published ratings: Dynamic load rating: 116 kN. Static load rating: 154 kN. Limiting speed: 5,300 rpm. Operating range: −40 °C to 120 °C. Mass: 1.76 lb. Running accuracy, radial and axial runout: P4. What these specs mean in practice: A tapered roller bearing takes heavy radial load and thrust in one direction at the same time, and the 322 steep-angle series shifts that balance further toward thrust. The flange on the outer ring locates the cup axially against a plain housing bore, which removes the need for a machined shoulder or a separate retaining ring. P4 accuracy is well above the standard class for tapered rollers and belongs on gearbox and machine-tool positions where shaft location and runout are held tightly. The static rating sitting above the dynamic rating is normal for tapered roller bearings. Quantity and configuration: Cone and cup together, matched as one bearing. Unit quantity: 1 Set. Fitting notes: Straight 55 mm bore. The cup flange seats against the housing face; the cone is pressed on to the shaft seat. Setting is by axial adjustment against the mating position in the arrangement. Interchange guidance: ISO base designation: 32211.
