Description
The 3308 A-2ZTN9/MT33 is a double row angular contact ball bearing with integral shields, combining high-speed capability with the capacity to handle relatively high radial and axial loads. Its back-to-back arrangement reduces the axial space required while maintaining stiffness and stability under operational stresses.
This bearing features a 40 mm bore, 90 mm outside diameter, and 36.5 mm width, with a contact angle of 30° for effective load distribution. It has a basic dynamic load rating of 65.5 kN and a static load rating of 48 kN, with a reference and limiting speed of 7,500 r/min. The CN axial internal clearance ensures reliable performance under varying conditions.
Constructed from premium bearing steel with a non-metallic cage and shields on both sides, the 3308 A-2ZTN9/MT33 is robust, durable, and suitable for machinery requiring stiff bearing arrangements, minimal maintenance, and extended service life. Typical applications include pumps, gearboxes, and high-speed rotating equipment.
