SKF 2216 ETN9 /C3 Self-Aligning Ball Bearing | High Clearance | 80x140x33 mm
The SKF 2216 ETN9 /C3 Self-Aligning Ball Bearing is engineered for applications where significant misalignment between the shaft and housing may occur, or where shaft deflection is expected. Featuring two rows of balls and a common spherical raceway in the outer ring, this design inherently compensates for angular errors without reducing service life. The standard bore diameter is 80 mm, with an outer diameter of 140 mm, and a width of 33 mm. The bearing utilizes the advanced ETN9 design, incorporating a highly resilient, glass fiber reinforced polyamide cage (PA66) which offers excellent strength, reduced inertia, and reliable performance even at higher operating temperatures compared to standard cage designs.
Optimized for reliability in demanding industrial environments such as fans, blowers, and textile machinery, the integral /C3 internal clearance designation ensures operational stability under conditions involving thermal expansion or heavy interference fits, preventing premature failure due to excessive bearing preload. This robust configuration provides low friction, allowing for cooler running and exceptional speed capability. Choosing the genuine SKF 2216 ETN9 /C3 guarantees maximum load capacity (95 kN dynamic), extended maintenance intervals, and the superior quality required for mission-critical rotating machinery.
