DodgeFC-IP-204RPiloted Flange Cartridge Spherical Roller Bearing Unit – 2-1/4 in Shaft, Clamp Collar, Heavy Duty, Rigid

Product Description

What this part is:

Dodge FC-IP-204R piloted flange cartridge bearing unit, Dodge part number 069818. Bearing type: Mounted spherical roller bearing, piloted flange cartridge. Housing Style: Piloted flange cartridge (FC). Locking Method: Clamp collar. Expansion Type: Rigid, non-expansion. Rolling Elements: Spherical rollers. Number Of Rows: 2. Relubrication: Yes, greasable. Duty rating: heavy duty.

Decoding the designation:

FC — flange cartridge, piloted. A machined register on the back face of the flange locates the unit in a bored recess in the mounting face, so the bearing centre is set by the pilot rather than by the mounting bolts.

IP — Dodge Imperial, the heavy-duty spherical roller bearing line. Two rows of barrel rollers run on a common spherical outer raceway, which carries heavy radial load with thrust in both directions and accommodates shaft misalignment on the raceway itself.

204 — Dodge bore code, read as whole inches and sixteenths: 2-04/16 = 2-1/4 in shaft.

R — rigid. The bearing is held axially in the cartridge, so this position fixes the shaft.

069818 — Dodge stock number for this build, the number distributors order against.

Housing style and mounting form:

Housing Style: Piloted flange cartridge. The pilot register on the back of the flange drops into a machined counterbore on the equipment face and takes the alignment, then the flange bolts hold it there. That is a tighter locating method than a plain flange, which relies on the bolt holes alone, and it is what a gearbox or drive end housing normally asks for.

What these specs mean in practice:

Bore / Shaft Size: 2-1/4 in. Rolling Elements: Spherical rollers, two rows. Locking Method: Clamp collar — the collar clamps concentrically around the shaft, so the inner ring runs true and holds in either direction of rotation. Expansion Type: Rigid. This unit sets the shaft position axially, and an expansion unit at the other end of the shaft absorbs thermal growth. Relubrication: Yes — the cartridge takes a grease fitting, so the bearing is serviced in place on a normal lubrication round.

A double-row spherical roller carries far more radial load than a ball bearing on the same shaft, takes thrust in both directions, and tolerates angular misalignment between shaft and housing because the outer raceway is a section of a sphere. That combination is why the Imperial line is specified on conveyor head and tail shafts, crushers, fans and other heavy shock-loaded drives.

Interchange guidance:

MPN Variants: FC-IP-204R, FCIP204R, FC IP 204 R, 069818. The FC-IP-204RE, Dodge stock number 071581, is the same cartridge at the same shaft size in the expansion build, and the two are commonly fitted as a pair at opposite ends of one shaft. The FC-IP-203R, Dodge stock number 069817, is the 2-3/16 in shaft member of the same family. Dodge codes shaft size in whole inches plus sixteenths across the FC-IP range, so 400R is the 4 in unit and 407L the 4-7/16 in unit.
