Designation:

• 30212 (DIN720, ISO355);
• 7212A (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. Tapered roller bearings are designed to accomodate combined loads (radial and axial).

Features:

Tapered roller bearings are designed to accomodate combined loads (radial and axial). They have a split construction: the inner ring with the rollers and separator create the unit which can be mounted separately from the outer ring.
This is a metric tapered roller bearing.
