This bearing carries axial loads in a single direction only, using a set of balls guided by a steel sheet metal cage (JP). The design has a height of 9.0 mm and a net mass of 27.0 g. It supports a limiting speed of 13100 1/min and a reference speed of 14000 1/min, making it suitable for applications requiring moderate rotational speed capability under one-directional axial loading. The single-direction design means this bearing cannot accommodate radial loads or axial loads from the opposite direction, so correct orientation during installation is essential. The steel sheet metal cage keeps the ball complement properly spaced and reduces internal friction, supporting stable operation at the rated speeds. This deep groove ball bearing is dimensionally and structurally interchangeable with SKF 51102, NSK 51102, and NTN 51102.
