Industrial MSC-19 Ball Bearing Cartridge Unit

Sealmaster MSC-19 Ball Bearing Cartridge Unit is a medium‑duty, cylindrical cartridge bearing designed to be mounted in a customer housing, delivering a 1‑3/16 in bore and a 3‑7/8 in outside diameter in a cast‑iron housing. The MSC‑19T variant (MSC Series) uses a Skwezloc locking collar, a 52100 bearing steel insert with a felt seal and flinger, and is rated for up to 6,500 rpm and operation from -30 °F to 250 °F, making it suitable for mid‑speed conveyors and material‑handling gear. Key dimensions include a housing width of about 1.2187 in, an inner ring width of 1 3/4 in, and a total weight around 3.5 lb; it is a non‑expansion bearing with lubrication via a fitting, and features a wide outer race and land‑riding retainer for shaft stability.
