The Sealmaster ER-43 ball insert bearing is a non-expansion, standard-duty straight-bore insert with a 2-11/16 in bore, an outside diameter of 4.921 in, and a 2.75 in width, secured to a shaft with a set-screw locking collar. It uses 52100 bearing steel, double nitrile rubber seals, and a brass cage, and is rated for up to 2,225 rpm with a temperature range of -20 to 220°F (-29 to 104°C). Designed for installation in compatible housings, the ER-43 provides reliable, sealed rotation in medium-duty industrial equipment that requires a robust insert bearing.
