NSK 90KBE42X double-row tapered roller bearing. Bore Diameter: 90 mm. Rolling Elements: Tapered Roller. Number Of Rows: 2. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel.
90 — bore diameter in millimetres.
X — boundary dimensions updated to the current ISO standard.
Two rows of tapered rollers on opposed raceways carry radial load and axial load in both directions from a single bearing position, and resist moment load across the spread between the two roller cones.
Tapered roller bearings have no contact angle figure in the angular contact ball bearing sense; their capacity is set by the roller taper and the raceway geometry. Lubricant: grease or oil.
Unit Quantity: 1 Pc, a single double-row assembly.
The carton designation 30218DF appears on this record as a size cross: it is a two-bearing face-to-face set of ISO 30218 single-row tapered roller bearings, not a single-part substitute.
