3209 A-2RS1TN9/MT33 Bearing Product Overview & Core Advantages
The 3209 A-2RS1TN9/MT33 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—both radial and bidirectional axial forces—thanks to its optimized contact angle and dual-row construction. Its compact design provides exceptional high rigidity support in constrained spaces, while the pre-lubrication and sealing ensure long-term performance with minimal maintenance. Engineered for high-speed applications and manufactured to P6 (ABEC-3) tolerance standards, this bearing delivers consistent performance in demanding industrial environments.

3209 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior high rigidity support, enabling the bearing to handle significant combined loads including radial forces up to 11,700 lbf dynamic rating and bidirectional axial loads simultaneously. The optimized contact angle distribution across two rows ensures stable operation under complex loading conditions.
High-Speed Performance: The TN9 stainless steel cage offers excellent strength-to-weight ratio, contributing to the bearing's ability to reach limiting speeds of 5,300 rpm. Combined with the optimized internal geometry and MT33 lubrication, this ensures smooth operation at elevated rotational speeds.
Maintenance-Free Operation: The double rubber seals (2RS1) provide effective protection against contaminants while retaining lubricant. Pre-filled with high-performance MT33 grease, the bearing operates reliably across a wide temperature range from -30°C to 110°C, making it suitable for long-term applications without requiring relubrication.
Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional controls, this bearing ensures precise running accuracy and minimal vibration for applications demanding high rotational precision.
