SKF 30210/VA9831 tapered roller bearing. Single-row tapered roller bearing designed to take combined heavy radial and one-direction axial load. Rollers, inner ring raceway (cone) and outer ring raceway (cup) are ground to converge at a common apex on the bearing axis. Two bearings are always mounted in opposition so the pair carries axial load in both directions and can be preloaded to remove all internal clearance. Metric dimensions per ISO 355 / ISO 492 Class Normal. Bore diameter d = 155 mm per ISO 15. Boundary plan per ISO 15 / ISO 355: bore d = 50 mm, outside diameter D = 90 mm, width B (or height H) = 21.75 mm.

Compatibility

ISO 15 boundary-plan interchange — the numeric bore-code block is portable across every ISO 15 bearing manufacturer (SKF, Timken, NSK, NTN, FAG, Koyo, NACHI). Confirm suffix compatibility on cage, seal, clearance and precision class before substitution.
