This deep groove ball bearing carries radial and moderate axial loads in a single row, sealed-free design with a steel sheet metal cage (JN). Bore diameter is 45.0 mm, outside diameter 75.0 mm, width 10.0 mm, and net mass is 0.16 kg. The limiting speed reaches 13100 1/min, with a reference speed of 6900 1/min, giving it capacity for higher rotational applications within its narrow cross-section. The radial internal clearance falls in group C3, exceeding standard clearance, which compensates for thermal expansion and interference fit effects under load. Bore type Z indicates a specific bore tolerance suited for precise shaft fitting. As this bearing has no integrated seals or shields, external protection and separate lubrication arrangements must be provided by the housing design. The steel sheet metal cage keeps rolling elements evenly spaced, supporting stable operation at the stated speed ratings.
