Product Overview: The 1280/1220 Tapered Roller Bearing
The 1280/1220 is a high-performance, single-row Inch Tapered Roller Bearing designed to manage both radial and axial loads simultaneously. This bearing consists of two separable components: the cone (inner ring assembly, part number 1280) and the cup (outer ring, part number 1220). With a bore diameter of 28.575mm, an outer diameter of 65.088mm, and a total width of 19.05mm, the 1280/1220 is engineered for applications requiring high load-carrying capacity and precise shaft guidance. The tapered geometry of the rollers and raceways creates a design that is exceptionally effective at handling combined loads, making it a staple in automotive and industrial machinery.
