SKF 1218 K – 90 mm Tapered Bore Self-Aligning Ball Bearing

SKF 1218 K – 90 mm Tapered Bore Self-Aligning Ball Bearing

The SKF 1218 K is a double-row self-aligning ball bearing with a tapered bore, designed to accommodate significant angular misalignment between the shaft and housing. Its unique design features a single concave outer ring raceway, which allows the bearing to pivot, compensating for shaft deflection or mounting errors. The tapered bore makes it suitable for secure mounting on a cylindrical shaft using an adapter sleeve, providing reliable performance in a variety of industrial applications.

About This Bearing

This product is a self-aligning ball bearing, a type of rolling-element bearing with two rows of balls. Its self-aligning capability is a key feature, as it allows the bearing to tolerate considerable shaft misalignment without affecting performance. The 1218 K part number provides crucial design information: the “K” suffix indicates a **tapered bore** with a 1:12 taper, which is designed for mounting on a cylindrical shaft using a separate adapter sleeve. This method provides a precise and secure fit. The bearing has a stamped steel cage and is designed to handle both radial and light axial loads, making it a versatile component for applications where alignment is a concern.
