Description
The 3308 A-2RS1TN9/MT33 is a double row angular contact ball bearing engineered for applications requiring high-speed operation and combined radial and axial load support. Its back-to-back configuration reduces axial space requirements compared to two single row bearings, providing a compact yet robust solution for industrial machinery.
Featuring a 40 mm bore, 90 mm outside diameter, and 36.5 mm width, this bearing has a 30° contact angle for optimal load distribution. It has a basic dynamic load rating of 65.5 kN and a static load rating of 48 kN, with a limiting speed of 5,000 r/min. The CN axial internal clearance ensures smooth performance across varying operating conditions.
Constructed from high-quality bearing steel with a non-metallic cage, the 3308 A-2RS1TN9/MT33 includes contact seals on both sides and grease lubrication to prolong service life while reducing maintenance. Ideal for gearboxes, pumps, and other machinery requiring stiff, compact, and reliable bearing arrangements.
