The INA-FAG NUM40 is a genuine cylindrical roller bearing, commonly identified as the NUM40-M1-C3 variant, engineered for high radial loads and speeds. This single-row bearing features an inner diameter of 40 mm, an outer diameter of 90 mm, and a width of 23 mm. It is typically constructed with a robust brass cage (M1) and possesses a C3 internal clearance, which signifies a greater than normal radial clearance, making it suitable for applications involving thermal expansion or potential misalignment. Manufactured by FAG (a brand of Schaeffler), this bearing ensures reliable performance and durability across various industrial machinery.
