The 2200–2215 series is engineered to accommodate angular misalignment of up to 2–3°, making it the go-to choice for applications where perfect shaft alignment cannot be guaranteed — from agricultural equipment and conveyor drives to industrial fans and textile machinery.\u003c\/p\u003e\n\u003cp\u003eEach bearing in this series features a double-row ball complement running in a spherical outer raceway ground into the outer ring. Inner bore diameters span 10 mm (2200) through 75 mm (2215), with corresponding outer diameters from 30 mm to 130 mm and widths from 14 mm to 31 mm. All dimensions conform to ISO 15 standards. Rings are manufactured from through-hardened bearing steel; retainers are pressed steel or machined brass depending on size.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include conveyor roller shafts where frame flex introduces misalignment, centrifugal fan pillow-block assemblies subject to thermal expansion, and agricultural PTO drive shafts exposed to vibration and shock loads.

Self aligning ball bearings are primarily designed for radial loads. They can accept light axial (thrust) loads — typically up to 20–30% of the basic dynamic radial load rating — but are not suited for applications where axial load is the dominant force. For heavy combined loading, angular contact or tapered roller bearings are more appropriate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat lubrication should I use and how often should I re-grease?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eLithium-based NLGI Grade 2 grease is suitable for most general industrial applications.
