3307 A-2RS1 Bearing Product Overview & Core Advantages
The 3307 A-2RS1 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. This precision bearing features integral seals and is pre-lubricated, making it suitable for arrangements where space is limited and maintenance access is difficult. Its design enables it to support substantial combined loads (radial and bidirectional axial loads) simultaneously, providing stable operation in demanding environments. Manufactured to P6 (ABEC-3) tolerance class, it ensures consistent performance and long service life.

3307 A-2RS1 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity compared to single row bearings, enabling stable support for combined loads in both radial and axial directions. With a dynamic load rating of 12,150 lbf and static load rating of 8,550 lbf, this bearing delivers reliable performance in heavy-duty applications.
Sealed & Lubricated Construction: The 2RS1 rubber seals effectively prevent contamination ingress while retaining lubricant, making the bearing suitable for dirty environments. Pre-lubricated with high-quality grease, it offers maintenance-free operation throughout its service life.
Precision Engineering: Manufactured to P6 tolerance class with chrome steel rings and balls, plus a stainless steel cage, this bearing ensures smooth operation and extended service life. The optimized internal geometry contributes to its limiting speed of 6,000 rpm.
Temperature Compatibility: Operating temperature range of -30°C to 110°C allows for use in various industrial environments without performance degradation.
