280*390*275mm 280RV3903(FCDP5678275/YA3) Rolling Mill Bearing

280*390*275mm 280RV3903(FCDP5678275/YA3) rolling mill bearing

This kind of bearings are the most widely used bearings for various rolling
Mills in the metallurgical industry.

1. Main characteristics

A. The bearings take on the largest value of dynamic load rating in limited space;
B. They can be used for high speed;
C. The bearings allow precise limiting tolerance;
D. The inner ring and outer components (outer ring, complete sets of
Rollers) are interchangeable, advantageous to quick roll changing;
E. The bearings can bear radial load only.

2. Bearing structure type

Based on the three basic structure, there are several variant structure:

FC...A type: Without oil groove or hole in the outside diameter, with oil groove on outer ring surface;

FC...B type: With oil groove and hole in the outside diameter, with oil groove on outer ring surface;

FC...E type: Without oil groove or hole in the outside diameter, with oil groove on outer ring surface, without rib in the outside diameter, integrated window cage;

FCD...A type: Without oil groove or hole in outside diameter, with oil groove on outer ring surface;

FCD...B type: With oil groove and hole in outside diameter, with oil groove on outer ring surface;

FCD...Y type: Without oil groove or hole in outside diameter, with oil groove on outer ring surface, with spacer between the two outer rings.

FCD...2LS type: Without oil groove or hole in outside diameter, sealed type;

FCDP...E type: With oil groove and hole in outer diameter, with oil groove in inner surface, dowel cage (hollow roller) or solid widowtype.
