A SEALMASTER SRC unit is a cartridge style bearing: an insert bearing seated in a cylindrical housing designed to sit in a machined bore. You choose this arrangement when the shaft needs support and the frame already provides the bore, so no feet or flanges are required. MR Industrial Accessories LLC supplies this line from Miami, Florida, to customers throughout the United States and in several Latin American countries.

Reading the code is the first step. The three letters SRC are followed by a size number, giving designations such as SRC-8, SRC-10, SRC-12, SRC-14, SRC-15, SRC-16, SRC-18 and SRC-19. That number is a size reference inside the series, not a shaft measurement and not a cartridge dimension on its own. To learn which shaft and which bore it matches, cross-reference it against the manufacturer's table. For that reason, order with the full code exactly as printed on the drawing or the machine nameplate.

You will find these cartridges on belt and chain conveyors, bucket elevators, mixers, dryers, pumps and other process equipment. Food, chemical, cement and aggregate plants use them because the cartridge drops into an existing bore, which means the unit can be replaced without tearing down the surrounding structure. Packaging machines and grinding lines also use them where the support has to be shielded from dust.

Selection comes down to a few checks: shaft diameter, housing diameter and depth, and the locking method of the insert. Sealing deserves attention as well. A contact seal suits dusty or wet conditions, and where washdown occurs, added protection is advisable. Lubricating the insert and aligning the housing both affect how long the unit lasts; a cartridge seated at an angle puts extra load on the seal and the raceway. Follow the manufacturer's instructions for axial adjustment during mounting.

Cartridge mounted bearings come from multiple brands, each with its own nomenclature, and they do not swap automatically. Compare shaft diameter, outer diameter, cartridge width, insert locking system and seal type before substituting. In many cases the housing matches across brands and only the insert differs. If you are holding another brand's code, send it with your housing dimensions and we will point you to a compatible option.

When a machine is down, message us on WhatsApp with the SRC code from the old unit, the brand and a photo of the housing. From there we can quote the SEALMASTER unit and, if it helps, a suitable equivalent. MR Industrial Accessories LLC also manufactures split plummer block housings, roller chains and sheaves, and stocks bearings, seals, bushings and lubricants to round out the repair.
