2205 E-2RS1KTN9 Bearing Product Overview & Core Advantages
The 2205 E-2RS1KTN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This sealed bearing excels at simultaneously handling combined loads (radial and bidirectional axial loads) due to its optimized contact angle and double row design. Its compact construction, featuring a 25 mm bore, 52 mm outside diameter, and 18 mm width, provides a space-saving solution without compromising performance. Pre-lubricated and sealed for life, it offers maintenance-free operation and consistent performance within a temperature range of -30° to 110 °C, making it an ideal choice for demanding industrial environments.
Model Code Breakdown
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| E | Optimized Internal Design | Enhanced load capacity and performance |
| 2RS1 | Double Contact Seals (NBR Rubber) | Superior contamination protection and grease retention |
| K | Tapered Bore (1:12) | Facilitates precise mounting and adjustment on tapered shafts |
| TN9 | Glass Fiber Reinforced Nylon Cage | Reduced friction, lightweight, and suitable for high-speed operation |
2205 E-2RS1KTN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact construction provides significantly higher rigidity compared to single row bearings, enabling stable support under combined radial and axial loads. With a dynamic load rating of 3218 lbf and static load rating of 900 lbf, it handles substantial operational stresses effectively.
High-Speed Performance: The TN9 polymer cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 9,000 rpm. This makes the bearing suitable for high-speed applications where smooth rotation is critical.
Maintenance-Free & Long Service Life: The integral 2RS1 rubber seals on both sides effectively exclude contaminants and retain the factory-applied lubricant. This sealed-for-life design ensures consistent performance and eliminates the need for relubrication, reducing maintenance costs and downtime.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The tight dimensional tolerances on the bore, outside diameter, and width guarantee precise fit and reliable operation in precision machinery.
