This deep groove ball bearing carries the designation 6301-2Z from FAG, built as a single row design with metal shields on both sides and a steel sheet metal cage (JN). Bore diameter is 12.0 mm, outside diameter 37.0 mm, width 12.0 mm, and net mass is 59.8 g. Radial internal clearance falls within CN (Group N), and the limiting speed reaches 24000 1/min, with a reference speed of 20000 1/min. The steel shields protect the rolling elements from dust and coarse contamination while retaining the internal grease fill, making this bearing suited for continuous operation without external maintenance intervention. The CN clearance and steel cage support stable running at the stated speed values, and the shielded design keeps the bearing sealed against basic environmental ingress on both sides. Dimensionally and constructionally interchangeable with SKF 6301-2Z, NSK 6301ZZ, and NTN 6301ZZ.
