The SEALMASTER RUBRB insert bearing belongs to the 100 series and consists of a ball bearing with an extended inner ring. It is intended for installation in split plummer block housings and wall units, where the shaft turns and the housing stays stationary. A key benefit is that the insert can be replaced without taking apart the whole assembly.
The RUBRB code denotes a family of SEALMASTER inserts made for housings. The three-digit number after it tells you the bore size and the locking method; RUBRB-112 and RUBRB-116, for instance, are different shaft sizes within the same 100 series. Suffixes that follow the number point to sealing or locking variations, so check the full part number before asking for a quote.
Typical installations include split plummer block housings, flange units and take-up units. You will see these inserts in conveyors, mixers, fans, pumps and process lines, as well as in aggregate processing equipment and agricultural machinery. In dusty or damp conditions, the right sealing choice matters.
When selecting, confirm the shaft diameter, the locking type (set screw, eccentric or adapter) and the seal needed for the environment. For mounting, clean the shaft and remove any burrs, seat the insert in the housing base, tighten the set screws against the inner ring and check housing alignment. Proper lubrication and correct axial clearance help the insert last; if vibration is present, inspect tightening and concentricity.
SEALMASTER is a Regal Rexnord brand. Its inserts can be interchanged with other brands when sizes, locking and sealing match. Matching the diameter alone is not sufficient: compare the inner ring width, set screw positions and seal type. If no exact equivalent is found, send the original part number and we will suggest a compatible alternative.
