The SKF 108TN9C3 is a genuine self-aligning ball bearing designed to accommodate angular misalignment between the shaft and housing. This double-row bearing features a 40 mm bore diameter, an 80 mm outer diameter, and an 18 mm width. It comes with a C3 radial internal clearance, which is greater than normal, allowing for thermal expansion or to compensate for fit tolerances. The TN9 suffix indicates a glass fibre reinforced polyamide 66 cage, offering good strength and low friction. Ideal for applications where shaft deflection or mounting errors are expected.
