DODGEF2B-SXV-1152-Bolt Flange Ball Bearing Unit 1-15/16″ Bore, Eccentric Collar, Self-Aligning, Cast Iron

Product Description

What this part is

A Dodge F2B-SXV-115 mounted ball bearing unit — a two-bolt flange block for a 1-15/16 inch shaft. The cast iron housing bolts to a vertical face through two diagonally opposed holes, and the SXV wide inner ring ball insert locks to the shaft with an eccentric collar. The spherical outer seat lets the insert swivel to take up shaft misalignment at installation.

Decoding the designation

F2B = Dodge two-bolt flange housing. SXV = intermediate-duty SX-series ball insert with eccentric locking collar. 115 = 1-15/16 inch bore. 130330 is the Dodge/Baldor part number for this build.

Housing style, read this before ordering

F2B is a two-bolt flange, not a four-bolt. The Dodge four-bolt square flange is F4B and it will not drop into an F2B footprint — different bolt pattern, different hole count. Neither one interchanges with a Dodge P2B pillow block, which mounts below the shaft on a horizontal base. Bolt count and pattern are part of the housing style, so confirm what your machine actually has before you buy.

What these specs mean in practice

An eccentric collar locks by cam action against the direction of rotation, so it holds well in one direction and can loosen if the shaft reverses under load. On a reversing drive, a setscrew or adapter-mounted insert is the safer choice. The wide inner ring gives the collar something to bear against and spreads the shaft load, which is why these units tolerate commercial-tolerance cold-drawn shafting rather than needing a ground seat.

Self-aligning means the insert swivels in the housing to compensate for shaft-to-housing angular error at setup. It does not compensate for a running misalignment that grows in service — align the drive properly and let the spherical seat handle the residual.

Quantity and configuration

Sold as one complete unit: cast iron flange housing with the SXV insert and its eccentric collar fitted. No mounting bolts included.

Fitting notes

Slide the unit onto the shaft, position it, then turn the collar in the direction of shaft rotation until it seats and tighten its setscrew onto the collar — not onto the shaft. Rotate the shaft by hand and check the insert swivels freely in the housing before final bolt-up. Purge the grease path with fresh grease of the same type before running.

Interchange guidance

SealMaster SF, Rexnord KF, Hub City FB and NTN UCFL are the equivalent two-bolt flange families in this bore, but flange face dimensions and bolt centres vary by maker, so measure before treating any of them as a drop-in. The insert alone is also available separately if your housing is sound — that is a different order code, and this listing is the complete unit.
