The 170 mm steel sleeve bearing is designed for use with bearing models 6022, 6219, and 6316, featuring an outer diameter of approximately 177 mm (6.969 inches) with a tolerance of ±0.05 mm and a sleeve length of 80 mm. Made from durable steel, this oversized sleeve ensures precise fit and reliable performance in heavy-duty applications. It supports deep groove ball bearings with standard boundary dimensions, suitable for radial loads and moderate speeds. The sleeve's robust construction enhances bearing alignment and longevity, making it ideal for industrial machinery requiring stable rotational support within a 170 mm housing diameter.
