Double Row Ball Self‑Aligning Bearing — Models 1216, 1217, 1218, 1219, 1220, 1221, 1222, 1224ATN (1220 size: 100 x 180 x 34 mm) Why choose this bearing Built as a double‑row, self‑aligning ball bearing to combine higher radial load capacity with automatic compensation for shaft misalignment. Reduces downtime and maintenance by tolerating small installation or shaft deflection errors without premature wear. Delivers low friction and smooth rotation for reliable performance in rotating assemblies. Key benefits Increased load capacity: The double‑row configuration shares radial loads across two rows of balls for better support than single‑row designs. Self‑alignment: Spherical raceway geometry allows the inner ring to tilt relative to the outer ring, correcting misalignment and reducing stress on components. Versatile compatibility: Offered in series 1216 through 1224ATN to fit a range of housings and shaft sizes; specifically, the 1220 model measures 100 x 180 x 34 mm for accurate replacement or retrofit needs. Primary attributes Design: Double row ball bearing with self‑aligning capability. Models included: 1216, 1217, 1218, 1219, 1220, 1221, 1222, 1224ATN. Size reference: Model 1220 dimension — 100 x 180 x 34 mm. Functionality: Supports radial loads, compensates for misalignment, provides low‑friction rotation. Applications: Suitable where moderate to radial loads and alignment correction are required. Typical uses and applications Industrial gearboxes and reducers: Replaces or upgrades bearings in gearboxes where shaft deflection or mounting tolerances cause misalignment. Conveyor and material‑handling equipment: Supports long shafts and rotating rollers while reducing downtime from bearing failures caused by misalignment. Agricultural and construction machinery: Handles heavy radial loads and varying operating conditions where alignment can shift during use. Installation and selection tips Match model number and dimensions exactly when replacing bearings; use the listed series (1216–1224ATN) and confirm the 1220 size (100 x 180 x 34 mm) when applicable. Allow for the self‑aligning feature during assembly—avoid forcing the bearing into applications that require fixed axial positioning unless design permits. Verify load direction and mounting conditions to ensure a double‑row self‑aligning ball bearing is the appropriate choice for your application. What this product delivers Reliable load support with alignment tolerance to extend component life and reduce maintenance. A straightforward drop‑in option across multiple standard sizes for , retrofit, or equipment design.
