Four-row Cylindrical Roller Bearing FC3854168

Four-row Cylindrical Roller Bearing FC3854168

Features:

This bearing is widely used for roller in metallurgy industry.
1.Main feature
a.Bearing features maximum rated dynamic load in restricted space.
b.Bearing can be used for high rotating speed equipment.
c.Shaft is allowed to have high precision tolerance.
d.Inner ring is allowed to be changeable with outer assembly(consisting of outer ring and roller set)to speed up roller change.
e.Bearing can bear radial load only.
2 Bearing structure machining
Based on three basic type of structure, the following can be done:
FC.....A type:Outer diameter without oil tank oil hole, outer ring with oil tank.
FC.....B type:Outer diameter with oil tank oil hole, outer ring with oil tank.
FC.....E type:Outer diameter without oil tank oil hole, outer ring with oil tank,outer ring without guide rib,integral window cage.
FCD... A type:Outer diameter without oil tank oil hole, outer ring with oil tank.
FCD....B type:Outer diameter with oil tank oil hole, outer ring with oil tank.
FCD....Y type:Outer diameter without oil tank oil hole, outer ring with oil tank,pin cage(hollow roller)or window cage.
3.Radial equivalent dynamic load Pr=Fr
4.Radial equivalent static load Por=Fr
