Description
The 3207 ATN9 is a double row angular contact ball bearing engineered for high-speed operation and applications requiring both radial and axial load support. Its back-to-back arrangement reduces the axial space needed while maintaining stiffness and load-handling capability, making it ideal for machinery where space is limited.
This bearing features a 35 mm bore, 72 mm outside diameter, and 27 mm width with a 30° contact angle for optimal load distribution. It has a basic dynamic load rating of 40.5 kN and a static load rating of 30 kN, with a reference and limiting speed of 9,000 r/min. The CN axial internal clearance ensures smooth operation under varying conditions.
Constructed from high-quality bearing steel with a non-metallic cage, the 3207 ATN9 provides reliable, long-lasting performance in industrial machinery, pumps, and gearboxes. Its design minimizes maintenance needs and offers dependable service life even under high-speed or heavy-load conditions.
