SEALMASTER USRB5500A series housings are mounted units with spherical roller bearings, designed for rotating shafts transmitting radial load and moderate thrust in continuous-duty equipment. The unit integrates the bearing, the housing and the shaft locking system, which simplifies assembly and reduces commissioning time. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, for plants that need reliable replacements and technical advice.

The USRB5500A series designation is read in blocks: the initial letters identify the type of mounted housing, the four-digit number defines the housing size and the final letter indicates the locking or sealing variant. In the examples USRBF5515A-207 and USRBF5520A-308, the numeric suffix after the hyphen indicates the shaft diameter with which each unit is assembled. Therefore, when requesting a replacement it is best to provide the complete part number: two units of the same series may differ in shaft diameter and locking type.

These housings are used in belt and roller conveyors, bucket elevators, mixers, mills, screens and process equipment in food, cement, mining and aggregate processing plants. In the Argentine market they also appear in road machinery, stockpiling belts and industrial ventilation systems. The combination of spherical roller bearing and robust housing makes them suitable for shafts with slight misalignment and combined loads, always within the limits indicated by the manufacturer for each size.

To select the right unit, check the shaft diameter, the shaft locking type and the sealing required by the environment. In areas with dust, water or frequent washing, contact seals and oil seals that protect the bearing should be prioritized. During assembly, verify the alignment of the housing with the shaft, the tightening of the anchor bolts and the initial lubrication. Poor alignment or uneven tightening shortens bearing life even if the unit is the correct one.

Mounted units of this type are interchanged between brands by shaft number and housing configuration, not by each manufacturer's catalogue code. If the original part number is not available, the equivalent is found by shaft diameter, bearing type, locking and sealing. MR Accesorios Industriales indicates the compatible alternative or, if necessary, manufactures it to measure. Send the part number or model via WhatsApp and we'll quote it shortly.
