30309 J2/Q [SKF] Tapered roller bearing - 45 X 100 X 27.25 MM
Manufacturer designation:
30309 J2/Q.
Designation via standards:
30309 - DIN 720, ISO 355.
Design:
The bearing consists of two rings (inner and outer) and rolling elements (tapered rollers) which are connected by a cage. The inner ring with a cage and rolling elements is a CONE. The outer ring is a CUP.
The design of tapered roller bearings suites for the perception of combined (radial and axial) loads. Tapered roller bearings have a split construction: the inner ring with the rollers and separator create the unit, that can be mounted separately from the outer ring.
