Product Description

What this part is

Sealmaster MSFT-23C two-bolt flange-mount ball bearing unit, Gold Line series. Bore: 1-7/16 in (1.4375 in), straight and round. Series: MSFT, medium duty. Housing: cast iron, two-bolt oval flange. Insert: wide outer race ball bearing with a spherical outside surface for self-alignment. Locking method: setscrew locking collar. Expansion type: non-expansion.

Decoding the designation

MSFT: medium-duty two-bolt flange unit. 23: 1-7/16 in bore. C: setscrew locking collar. Series: MSFT. Duty rating: medium.

Housing style and bolt pattern

Two-bolt oval cast iron flange. Bolt hole spacing width: 5-21/32 in (5.656 in). Overall length: 6-3/4 in. Flange height: 9/16 in. Weight: 3.80 lb.

What these specs mean in practice

The medium-duty MSFT housing carries a heavier section than the standard-duty SFT at the same bore, so it takes more shock load off a drive shaft in conveyor and fan service. The spherical insert outside surface takes up initial shaft misalignment on mounting. Setscrew locking is the quickest field fit on a commercial shaft and reverses out without a special tool.

Sealing and lubrication

Felt seal with flinger on both sides, which balances contaminant exclusion against grease retention and running friction. Regreasable through the housing fitting. Factory grease: Sealmaster GoldPlex HP. Insert construction: black oxide treated bearing steel with a land-riding metallic retainer and a lock pin and dimple system securing the outer race in the housing.

Quantity and configuration

One complete flange unit with insert and setscrew collar. Country of origin: United States. Harmonization code: 8483.20.40.

Interchange guidance

MSFT-23T is the same unit with a Skwezloc concentric locking collar — a related locking variant. SFT-23C is the standard-duty housing at the same bore — a related duty grade. Searchable forms: MSFT23C, MSFT 23 C, MSFT-23-C.
