3201 A-2ZTN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior stiffness compared to single row bearings, enabling stable operation under significant combined loads. The optimized raceway geometry and bearing dimensions (12mm bore × 32mm OD × 15.9mm width) ensure efficient load distribution across both rows.
High-Speed Performance: The TN9 stainless steel cage minimizes centrifugal forces and friction, while the precision P6 (ABEC-3) tolerance class ensures smooth operation up to 22,000 rpm. The balanced design reduces vibration at elevated speeds.
Maintenance-Free Operation: With double shields (2Z) and factory-filled MT33 grease, this bearing offers long-term protection against contamination and lubrication loss. The sealed design makes it ideal for applications where re-lubrication is difficult or impossible.
Material Excellence: Manufactured from chrome steel for both rings and balls, the bearing provides excellent wear resistance and durability. The stainless steel cage offers corrosion resistance in challenging environments.
