This deep groove ball bearing carries radial loads and moderate axial loads in a single row, ball-and-race arrangement with a 55.0 mm bore, 120.0 mm outside diameter and 29.0 mm width. Mass is 1.4 kg. The bearing is fitted with a steel sheet metal cage (JN design) and reaches a limiting speed of 7900 1/min, with a reference speed of 7200 1/min. Radial internal clearance is CN (Group N), the standard clearance range, suitable for normal fit and temperature conditions without preload issues. The open design (bore type Z) allows the mounting side to be lubricated and inspected directly, and the steel cage supports stable ball guidance at the stated speed range. This configuration suits applications requiring standard clearance and a robust, low-mass cage under normal running conditions.
