This single row deep groove ball bearing carries a 140.0 mm bore, 250.0 mm outside diameter and 42.0 mm width, with a net mass of 7.804 kg. It is fitted with a steel sheet metal cage (JN) and radial internal clearance C3 (Group 3), giving it a larger internal clearance than standard for compensating thermal expansion during operation. Limiting speed and reference speed are both rated at 3600.0 1/min. The C3 clearance suits applications with interference fits or elevated operating temperatures, where a normal clearance bearing would run too tight. The steel sheet metal cage keeps the design lightweight while guiding the balls at the stated speed rating. No sealing or shielding is integrated, so lubrication and contamination protection must be provided externally by the housing arrangement. Dimensionally and constructionally equivalent to SKF 6228/C3, NSK 6228C3 and NTN 6228C3.
