Product Description

What this part is
A Link-Belt FX3U223N mounted ball bearing unit: a self-aligning wide-inner-ring insert bearing in a two-bolt oval cast iron flange housing, bored 1-7/16 in and locked to the shaft with set screws. The housing bolts to a vertical wall or bulkhead with the shaft passing through it.

Designation breakdown
F: flange housing. X: two-bolt oval flange style. 3U: Link-Belt standard-duty mounted unit series with a set-screw locking wide inner ring insert. 223: size code, 1-7/16 in bore in the 200 series envelope. N: non-expansion (fixed) unit.

Specifications
Manufacturer: Link-Belt (Regal Rexnord). Part Number: FX3U223N. Base Number: FX3U223. Regal Rexnord Material Number: 10073990. Bearing Type: mounted ball bearing unit, self-aligning wide inner ring insert. Housing Style: two-bolt oval flange block. Mounting Arrangement: flange mount. Number of Bolt Holes: 2. Bore / Shaft Size: 1-7/16 in (1.4375 in). Bolt Center to Center: 5.1250 in. Housing Material: cast iron. Insert Outer Ring: spherical. Locking Method: set screws in the extended inner ring. Closure Type: single lip contact seal. Relubrication: yes, grease fitting provided. Lubricant: grease. Expansion Type: non-expansion (fixed). Rolling Elements: balls. Number of Rows: 1. Dynamic Radial Load Rating: 5,810 lbf. Static Radial Load Rating: 3,440 lbf. Maximum Speed: 4,800 rpm. Maximum Operating Temperature: 225 °F. Series: Link-Belt 200 series standard duty, FX3U flange. Design Units: imperial (inch). Item Weight: 3.20 lb.

What these specifications mean in practice
Standard-duty 200 series mounted units carry shafting under radial or combined radial and thrust loads in conveyors, fans, blowers and chain and belt drives. The insert’s spherical outside diameter swivels in the housing seat, so the unit self-aligns to a fabricated frame without preloading the balls. The N non-expansion designation means this unit locates the shaft axially.

Set composition
One complete flange block unit: cast iron housing, insert bearing, single lip seal, set screws and grease fitting as an assembly. Mounting bolts and shaft key are not included and the unit ships without its original carton.

Interchange
Link-Belt mounted bearings are now part of Regal Rexnord, so the same unit appears as Rexnord Link-Belt FX3U223N and under material number 10073990. Dimensionally comparable 1-7/16 in two-bolt flange blocks: Dodge F2B-SC-107, SealMaster SF-23, Browning VF2S-123, Timken VF2S 1 7/16, NTN UCFL207-107, SKF FYT 1.7/16 TF. Within Link-Belt, FX3S223 is the same bore in the two-bolt flange with a different locking and sealing arrangement, and F3U223N is the four-bolt square flange in the same size.
