This deep groove ball bearing carries radial loads together with limited axial loads in either direction, using a single row of balls running in deep raceway grooves. Bore diameter is 140.0 mm, outside diameter 210.0 mm, width 33.0 mm, and net mass 3.57 kg. The cage is a steel sheet metal design (JN), radial internal clearance is CN (Group N), and the limiting speed reaches 4250.0 1/min with a reference speed of 4050.0 1/min. The CN clearance suits standard mounting conditions without preload, and the sheet metal cage keeps mass low while guiding the balls at higher speeds. With no seals or shields fitted, lubrication must be supplied and maintained externally, so the bearing is intended for housings where grease or oil feed and contamination control are handled by the surrounding assembly. Dimensionally and constructionally it corresponds to SKF 6028, NSK 6028 and NTN 6028.
