| High Light | Double row self-aligning ball bearing 20x47x14mm ，Self-aligning ball bearing with extended inner ring ，11204ETN9 self-aligning bearing 40mm inner ring | ||
This 11204 double row self-aligning ball bearing series (covering 11204ETN9, 11204 TN, and 11204 TN9 variants) is engineered for industrial machinery requiring misalignment compensation and reliable load support. Featuring key dimensions 20mm ID * 47mm OD * 14mm Width, plus a 40mm extended inner ring for enhanced mounting adaptability, it’s crafted from premium GCr15 bearing steel (hardness 58-62 HRC) with precision-ground raceways.
The self-aligning design accommodates up to 2° of angular misalignment (from shaft/housing inaccuracies), while the extended inner ring simplifies installation on diverse shaft configurations. This 11204 self-aligning ball bearing delivers long-term wear resistance for continuous, moderate-load operations in harsh industrial environments.

Q: What’s the purpose of the self-aligning function in this bearing?
A: It compensates for angular misalignment (up to 2°) between the shaft and bearing housing, reducing wear caused by mounting errors or shaft deflection in operating equipment.
Q: Why choose the extended inner ring (40mm) model?
A: The 40mm extended inner ring provides longer axial contact with the shaft, enhancing mounting stability—especially suitable for heavy-vibration scenarios (e.g., agricultural machinery).
Q: What do "TN" and "TN9" mean in the model number?
A: Both refer to nylon cage configurations; "TN9" is a standard suffix for self-aligning ball bearings with nylon cages, ensuring low-noise, low-friction operation.
