3204 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling stable operation under combined loads. With a radial dynamic load rating of 4590 lbf and static rating of 2902 lbf, this bearing delivers reliable performance in demanding applications.
High-Speed Performance: The TN9 polymer cage reduces centrifugal forces and friction, contributing to the bearing's limiting speed of 10,000 rpm. Combined with precision P6 (ABEC-3) tolerance class, this ensures smooth operation at elevated rotational speeds.
Maintenance-Free Operation: The 2RS1 contact seals effectively prevent lubricant leakage and contamination ingress, while the pre-filled MT33 high-performance grease provides long-term lubrication throughout the operating temperature range of -30°C to 110°C.
Premium Materials: Constructed from chrome steel rings and balls with stainless steel cage, this bearing offers excellent durability and corrosion resistance, ensuring extended service life in various operating conditions.
