This deep groove ball bearing carries radial and moderate axial loads on a single row of balls guided by a steel sheet metal cage (JN). Bore diameter is 12.0 mm, outside diameter 37.0 mm, width 12.0 mm, net mass 59.8 g, and the limiting speed reaches 13700 1/min. Radial internal clearance is CN (Group N), the bore type is Z, and seals are fitted on both sides, sealing the bearing for life. The integrated seals keep grease inside and contaminants out, so no external sealing or maintenance is required during operation. With standard CN clearance, this bearing suits shaft arrangements without special preload requirements, and the steel cage gives it stable guidance at the stated speed limit. Dimensionally and constructionally equivalent to SKF 6301-2RS1, NSK 6301DDU, and NTN 6301LLU.
