Part of the SEALMASTER line, the MSF bracket is a four-bolt flange unit that carries an insert bearing. It mounts to a flat surface and supports a rotating shaft, with the insert held inside the flange and the assembly fixed by bolts. It fits applications where the shaft sits horizontally, the load is mainly radial and some axial thrust is present depending on the insert used. MR Industrial Accessories LLC supplies this bracket and handles quotes by WhatsApp or email.

In the MSF family, the three letters identify the series and the trailing number orders the sizes inside it. That number is a size reference assigned by the manufacturer to a specific flange-and-insert combination; it is not a diameter and not a millimeter measurement. The codes shown here are examples of how that progression runs. To pick the right one, provide the complete code plus the shaft dimensions at the mounting point.

Typical installations include conveyors, belts, elevators, mixers, blowers and process lines, as well as agricultural machinery and washing equipment. Mounting through a flange lets you fasten the four holes from a single side, which solves shaft support on sheet metal or structural frames without machining. Food plants, meatpacking operations, mills, water treatment facilities and material handling equipment are common places to find them.

Selection comes down to shaft diameter, load type and thrust direction. The insert seal determines what environment the unit can handle, since a dusty area and a washdown area are not the same duty. At installation, set the flange on a flat, clean surface, tighten the four bolts in a cross pattern and verify shaft alignment before startup. Lubrication and internal clearance follow the insert that comes with the bracket.

When comparing four-bolt flange brackets across brands, work from the hole spacing, the shaft diameter and the center height. A similar-looking code is not enough; those dimensions have to be cross-referenced. If the code you need is not among the examples in the series, send the model or the dimensions over WhatsApp and we will point you to a compatible option or quote it to your measurements.
