SEALMASTER SSF3S-120S flange bearing 3 holes

SEALMASTER SSF3S-120S belongs to flange bearing 3 holes, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for SSF3S-120S and any equivalents.

For shafts that need support where radial space is tight, the SEALMASTER SSF3S provides a 3-bolt flange mounting solution. The housing bolts to a flat surface with three fasteners, and the insert bearing rotates on the shaft. The load line runs through the center of the flange, which helps distribute forces. Typical applications include conveyors, agitators, and process equipment.

The SSF3S series code breaks down into sections: letters denote the housing style and flange arrangement, the following number gives the nominal insert size, and any trailing letters specify sealing or locking options. For instance, SSF3S-120S is a particular size within the SSF3S 100 family. To ensure you get the right part, share the complete part number when requesting a quote.

You will find these flange units on belt and chain conveyors, mixers, blowers, centrifugal pumps, industrial washers, and packaging lines. In food and beverage processing, chemical plants, and cold storage, the 3-bolt design allows mounting on sheet metal or a machined face where access is limited. They also serve in water treatment and agricultural machinery, where wet or dusty conditions call for a well-sealed insert.

When selecting, verify the shaft diameter, flange hole size, the distance between the three bolt centers, and the load line position. Consider the insert sealing: in wet or particle-laden environments, a contact lip in good condition is recommended. During installation, place the flange on a clean, flat surface, tighten the three bolts in a cross pattern, and align the shaft before final torque. Lubricate the insert according to the duty cycle and check axial play.

For equivalents, flange mounted bearings interchange by configuration, shaft diameter, and hole spacing—not by part number alone. A 3-bolt housing from another manufacturer can replace the SSF3S if those dimensions and the insert locking type match. If you are replacing a SEALMASTER reference, send us the old part number along with the shaft and flange dimensions, and we will identify a compatible alternative.

MR Industrial Accessories supplies the SEALMASTER line and manufactures split plummer block housings, ANSI chains, and sheaves.
