3201 A-2RS1TN9/MT33 Bearing Product Overview & Core Advantages
The 3201 A-2ZTN9/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 radial and bidirectional axial loads due to its optimized contact angle and double row design. Its compact construction (12 mm bore, 32 mm OD, 15.9 mm width) makes it ideal for space-constrained, high-performance assemblies. The bearing delivers exceptional high rigidity and stable operation, supported by P6 (ABEC-3) precision tolerances and premium chrome steel components.
Model Code Breakdown
| Suffix | Technical Meaning |
|---|---|
| A | Optimized contact angle design for enhanced load capacity |
| 2Z | Double-sided steel shields providing effective contamination protection |
| TN9 | Stainless steel cage enabling high-speed performance and corrosion resistance |
| MT33 | High-performance grease lubrication for extended service life across -30° to 110°C |
3201 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and stability, effectively handling combined loads (2,272 lbf dynamic, 1,260 lbf static ratings). The optimized contact angle ensures reliable bidirectional axial load support.
High-Speed Capability: The TN9 stainless steel cage minimizes centrifugal forces, while the precision-ground components maintain stability at limiting speeds up to 15,000 rpm.
Maintenance-Free Operation: Integrated 2Z steel shields and factory-applied MT33 grease create a sealed, lubricated system that requires no relubrication throughout its service life.
Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with strict dimensional controls (bore: -0.007/0 mm, OD: -0.009/0 mm) for consistent performance in precision applications.
