3302 A-2RS1TN9/MT33 Bearing Product Overview & Core Advantages
The 3302 A-2RS1TN9/MT33 is a double row angular contact ball bearing designed for high-performance applications. This precision bearing excels at simultaneously handling combined radial and bidirectional axial loads. Its compact design, featuring a 15 mm bore and 42 mm outside diameter, offers a high rigidity solution in a minimal space. Pre-lubricated and sealed, it is engineered for high reliability and extended service life in demanding operational environments.
Model Code Breakdown
- 3302: Basic designation indicating a double row angular contact ball bearing with a 15 mm bore diameter.
- A: Signifies a 30° contact angle, optimized for high axial load capacity.
- 2RS1: Denotes the bearing is fitted with two rubber contact seals (RS1) on both sides, providing superior protection against contamination.
- TN9: Indicates the cage material is glass fiber reinforced polyamide 66 (PA66), contributing to low weight, quiet operation, and high-speed capability.
- MT33: Specifies the bearing is pre-lubricated with a high-performance lithium soap complex grease, suitable for a wide temperature range and offering long-term lubrication.
3302 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides significantly higher radial and axial rigidity compared to single row bearings, making it ideal for applications with complex combined loads and moment forces.
High-Speed Performance: The lightweight TN9 polymer cage reduces centrifugal forces, while the optimized internal geometry and effective MT33 lubrication work in concert to achieve a high limiting speed of 12,000 rpm.
Maintenance-Free Operation: The combination of two effective rubber seals (2RS1) and a high-quality pre-filled grease creates a sealed-for-life unit. This design prevents lubricant leakage and ingress of contaminants, ensuring long-term, maintenance-free performance.
Precision & Reliability: Manufactured to P6 (ABEC-3) tolerance class, this bearing ensures precise running accuracy and consistent performance, which is critical for precision machinery.
