Housed in a one‑piece cast iron shell, it uses a 52100 bearing steel ball bearing (2-14T SFB) and is designed as a non‑expansion (fixed) bearing with a concentric collar locking to achieve near‑perfect concentricity. The unit incorporates a felt labyrinth seal and a land‑riding retainer to improve lubrication retention, along with a lock‑and‑pin\/dimple feature for direct lubrication. Key dimensions include a 4.125 in bolt center‑to‑center length, a 4.125 in bolt circle diameter, bore 1.25 in, outside diameter 5.0 in, housing width 5.0 in, and a 3.375 in pilot diameter, with an overall length of 5.0 in and an overall height of 1.375 in. It is relubricatable and uses lithium complex NLGI 2 grease, with a maximum operating temperature of 220 °F and a dynamic load rating of 5,782 lbf (static 3,493 lbf). Maximum speed is listed at about 6,500 rpm, with some documentation noting a higher cap (up to 7,600 rpm) depending on the listing. The SFC‑20T is part of Sealmaster’s SFC series and is designed for reliable shaft support in fixed flange installations where precise alignment and robust load capacity are required. \u003c\/p\u003e\u003c\/div\u003e","brand":"SealMaster","offers":[{"title":"New","offer_id":46283514020074,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-020.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/sealmaster-sfc-20t-piloted-flange-cartridge-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
