Single row deep groove ball bearing with a bore diameter of 95.0 mm, outside diameter of 145.0 mm and width of 24.0 mm, mass 1.29 kg. The bearing is fitted with steel sheet metal shields on both sides and a steel sheet metal cage (JN). Radial internal clearance is C3 (Group 3), above the normal range. Limiting speed is 5400 1/min, reference speed 5300 1/min. Dimensionally and constructionally equivalent to SKF 6019-2Z/C3, NSK 6019ZZC3 and NTN 6019ZZC3. The C3 clearance compensates for temperature rise and interference fit effects during operation, keeping the bearing free of excessive preload after mounting. The shields on both sides restrict ingress of coarse contaminants while allowing use with grease lubrication already present inside the bearing; they are not full contact seals, so they do not provide sealing against liquids or fine dust. The steel sheet metal cage suits the stated speed range and radial load direction typical of single row deep groove ball bearings, without accommodating significant axial misalignment beyond the standard tolerance of this bearing type.
