3309 2RS | SDKF | Double-Row | Angular Contact Ball Bearings

The 3312-2RS SDKF bearing is a high-performance double-row angular contact ball bearing designed to deliver exceptional strength, stability, and durability under demanding operating conditions. Built to handle high radial loadsalong with axial loads in both directions, it is widely used in machinery that requires reliable and smooth rotational performance.

A key advantage of this bearing is its 2RS sealing system, which features high-quality rubber seals on both sides. These seals effectively protect the bearing from dust, moisture, and other contaminants while locking in the lubricant. This ensures longer grease life, reduced wear, and minimal maintenance—ideal for equipment operating in harsh or dirty environments.

At the heart of its construction is a precision-engineered cage, typically made from pressed steel or reinforced polyamide, depending on the specific SDKF variant. This cage ensures optimal ball spacing, reduces friction, improves heat dissipation, and enhances overall operating efficiency. Its strong and stable structure helps the bearing run quietly and smoothly, even under heavy loads or higher speeds.

Crafted from premium bearing steel, the 3312-2RS SDKF offers excellent resistance to wear, deformation, and fatigue, ensuring long service life and consistent performance. Thanks to its dual-row design, it provides increased rigidity, making it ideal for applications with combined or fluctuating loads.

Common applications include industrial machinery, agricultural equipment, gearboxes, pumps, conveyors, and automated systems, where reliability and long-lasting performance are essential.

If you need a bearing that offers excellent load capacity, reliable sealing, smooth operation, and durable cage construction, the 3312-2RS SDKF is a dependable and widely trusted solution.

Its optimized internal design ensures smooth rotation, reduced friction, and stable performance even under heavy loads or continuous operation. The SDKF 7203 BECBP also offers low vibration and enhanced durability, helping maintain precision and efficiency in critical equipment.

Whether used for replacements or new installations, the SDKF 7203 BECBP is a dependable choice for operations requiring accuracy, strength, and long service life.
