Steyr 30210C Tapered Roller Bearing Set Cup Cone

Steyr 30210C Tapered Roller Bearing Set Cup Cone is a two-piece tapered roller bearing set (cup and cone) designed for single‑row radial and axial load handling. It pairs an outer race (cup) with an inner race assembly (cone) and is sized for a bore of 50 mm (1.9685 in) and an outer diameter of 90 mm (3.5433 in), with a typical overall width of 21.75 mm. This configuration uses tapered rollers that ride between matched raceways to sustain precision preload and load distribution in applications that call out the 50x90x21.75 mm tapered bearing set. The designation is commonly encountered across multiple brands for replacement in equipment that requires a 30210-series cup-and-cone assembly, and some listings note a Class 0 precision rating for this size. As a separable bearing, the cone and cup can be installed separately in compatible housings for simpler assembly and replacement. Always verify compatibility against your equipment’s OEM specifications before replacement.
