Product Description

What this part is:

RHP MSF1-3/8 Self-Lube four-bolt square flange bearing unit for a 1-3/8 in shaft. Cast iron housing to BS1452 with a spherical self-aligning insert, setscrew locking, nitrile / fabric seals and C3 internal clearance. Manufacturer: RHP, now part of NSK. Unit Quantity: 1 Pc, one complete flange unit with housing, insert bearing, seals and grub screws.

Decoding the designation:

MSF — RHP’s Self-Lube four-bolt square flange cast iron unit.

1-3/8 — the bore in inches, 34.93 mm.

MSF-22 — the RHP casting group marking cast into the housing for this size.

Specifications:

Part Number: MSF1-3/8. Casting Group: MSF-22. Series: MSF, RHP Self-Lube four-bolt square flange. Bore / Shaft Size: 1-3/8 in (34.93 mm). Housing Style: four-bolt square flange, cast iron. Bolt Count: 4. Housing Material: cast iron to BS1452. Insert: spherical outer surface, self-aligning. Locking Method: setscrew (grub screw). Seal Type: nitrile / fabric. Internal Clearance: C3. Number Of Rows: 1. Rolling Elements: steel balls. Design Units: Inch. Country of Origin: United Kingdom.

Dimensions and mounting:

The four holes sit at the corners of a square, so the unit bolts to a face perpendicular to the shaft with the shaft passing through the flange. The insert seats in a matching spherical bore in the housing and swivels to take up initial misalignment between the shaft and the mounting face. Two grub screws in the extended inner ring clamp the insert to a plain shaft. Nitrile / fabric seals at both faces hold the factory grease charge. The unit is a complete assembly and can be removed and refitted without breaking the housing.

Compatibility and replacement:

Within the RHP Self-Lube range the same insert size appears in other housings: SFT is the two-bolt oval flange, SF is the standard square flange, and the pillow block styles bolt to a base parallel to the shaft. Search forms: MSF1-3/8, MSF 1-3/8, MSF 1 3/8, MSF1 3/8, MSF-1-3/8, MSF1.3/8, MSF-22, MSF 22.
