The SEALMASTER RUBRB 100 series is a ball bearing insert with an extended inner ring, made to sit in split plummer block housings and bearing units. It suits equipment that needs steady rotation and straightforward alignment, including conveyors, fans and process machinery. MR Industrial Accessories LLC supplies this line and can help you match the insert to your application.

Reading the code is simple once you know the pattern. RUBRB points to the SEALMASTER insert family intended for split plummer block housings, and the digits that follow give the bore in millimeters, as in RUBRB-30MM. The MM ending confirms a metric bore. Other references in the series can differ in sealing or locking method, but the logic stays the same: family letters, bore size, unit type. Send the full part number and you get the exact reference quoted.

Typical users are in food and beverage processing, logistics and aggregate handling. The inserts turn up on belt conveyors, bucket elevators, mixers, blowers and packaging lines. Because the inner ring extends beyond the bearing width, mounting on the shaft is easier and different locking arrangements can be matched to the housing. As part of the SEALMASTER line, these inserts handle dusty, damp or washdown conditions.

Selection comes down to three things: shaft diameter, housing style and the environment. Sealing deserves attention, since humid air or airborne particles call for extra protection. Pick a lubricant that fits the running speed and temperature, and make sure shaft and housing are aligned during mounting so the bearing is not loaded unevenly. Where vibration is present, check clearance and confirm the inner ring is locked correctly.

On interchangeability, SEALMASTER RUBRB 100 series inserts can be replaced by other brands with comparable sizes and configurations, but the housing dimensions and locking method decide whether it truly fits. A matching bore is not enough: verify inner ring width, hole positions and seal type. Give us the original part number and we will point you to a compatible option.
