SKF Tapered roller bearings

SKF tapered roller bearing single row, 30203 J2, 17 x 40 x 13.25

Bearing series 302
Tapered roller bearings have conically shaped raceways in the inner and outer rings, between which tapered rollers are arranged. The apexes of all conical surfaces meet at a common point on the bearing axis. Therefore, tapered roller bearings are particularly suitable for accommodating combined (radial and simultaneously axial) loads. Due to their internal design, single-row tapered roller bearings cannot be used alone but only together with a second bearing or as a bearing pair. Tapered roller bearings are generally not self-retaining. The inner ring with rollers and cage can be mounted separately from the outer ring. Main dimensions DIN 616:2000 / DIN-ISO 335 / DIN 720:1979

Additional designations:
