This single row deep groove ball bearing supports radial loads with a bore diameter of 240.0 mm, outside diameter of 360.0 mm, and width of 37.0 mm, giving a narrow cross-section for the given bore size. The cage is designated JN, executed as a steel sheet metal cage guiding the ball set. Net mass is 12.7 kg. Limiting speed is rated at 2450 1/min, with a reference speed of 2100 1/min, marking the thermally stable operating point under normal load and lubrication conditions. The radial internal clearance falls in group C3, wider than normal, which accommodates thermal expansion of the shaft and housing during operation and allows for interference fits without eliminating clearance. Bore type Z indicates the bore modification as specified by the manufacturer for this variant. The narrow width combined with the C3 clearance suits mounting arrangements where a tight fit is required on both rings while maintaining smooth rotation under temperature rise.
