Deep groove ball bearing 16016-C3 carries radial loads in a single row, narrow-width design with a bore of 80.0 mm, outside diameter of 125.0 mm and width of only 14.0 mm, giving a low axial footprint at a net mass of 0.59 kg. The steel sheet metal cage (JN) guides the ball complement, and the bearing is rated for a limiting speed of 7700.0 1/min and a reference speed of 4600.0 1/min. The C3 radial internal clearance (Group 3) provides a larger-than-normal clearance, compensating for thermal expansion under operating temperature rise and allowing stable running at the stated speed ratings. Bore type Z should be checked against the shaft fit tolerance during mounting. The slim 14.0 mm width suits applications where axial space is restricted while still requiring the 80.0 mm bore load path, and the steel cage keeps ball guidance consistent across the full speed range listed above.
