Product Overview: The 3318 Double-Row Angular Contact Ball Bearing
The 3318 bearing is a high-performance component from our 3300 Series of Angular Contact Ball Bearings. With dimensions of 90x190x73mm, this bearing is engineered to handle combined radial and axial loads in both directions, making it an exceptionally versatile and rigid solution for demanding applications. Its double-row design provides a high load-carrying capacity in a compact axial space, effectively functioning like two single-row angular contact ball bearings mounted back-to-back but requiring less space.
As a premier supplier of industrial components, we ensure our 3318 bearings are manufactured from high-grade bearing steel to meet stringent industry standards. This results in superior performance, durability, and a long service life. It is an ideal choice for applications where rigid shaft guidance is critical and deflection must be minimized. Explore our complete range of angular contact ball bearings for all your industrial machinery needs.
Key Features of the 3318 Bearing
- Double-Row Design: Offers high load capacity for both radial and axial forces in both directions, providing robust support.
- High Rigidity: The construction provides stiff bearing support, which is critical for applications requiring high running accuracy.
- Combined Load Accommodation: Capable of supporting complex load conditions, including significant radial and axial forces simultaneously.
- Space-Saving: Delivers the performance of two single-row bearings in a more compact and narrower design.
- Durable Construction: Made from high-quality, clean bearing steel for enhanced strength and resistance to wear.
- Precision Engineering: Manufactured for low friction and smooth operation, contributing to machine efficiency and longevity.
Common Applications
- Pumps and Compressors: Provides rigid and reliable support for shafts under combined loads.
