Designation:

• 30213J (DIN720, ISO355);
• 7213 (GOST 27365-87)

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.

Features:

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.
Tapered roller bearings are metric.
