SKF 6308 2RSNRJEM Ball Bearing

SKF 6308 2RSNRJEM is a single‑row deep‑groove radial ball bearing with a 40 mm bore, 90 mm outer diameter, and 23 mm width. It incorporates dual rubber seals on both sides (2RS) to retain lubrication and protect the raceways from contamination, while an outer‑ring snap‑ring groove (NR) enables the use of a retaining ring in compatible housings or shafts. The bearing is specified with radial internal clearance class C3, allowing slightly more play to accommodate mounting tolerances and thermal expansion in real‑world service. Construction materials include bearing steel with a steel cage for durable, precise ball guidance under load. This SKF variant is designed for sealed, low‑maintenance operation in compact machinery where reliable radial support is required, and the 2RSNRJEM code identifies the specific sealed, snap‑ring‑gable variant within the SKF 6308 family. In short, it’s a robust, ready‑to‑install option for applications needing a sealed, single‑row deep‑groove bearing in a 40x90x23 mm footprint.
