SKF Tapered roller bearings

SKF tapered roller bearing single row, 30208 J2/Q 40 x 80 x 19.75

Bearing series 302
Tapered roller bearings have conical 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:
J2 Window cage made of sheet steel
Q Optimized contact geometry and surface quality.
