The SKF 6217 Single Row Deep Groove Ball Bearing is a high-performance, precision-engineered component designed to meet the demanding requirements of modern machinery. As part of SKF’s renowned deep groove ball bearing series, the 6217 model exemplifies durability, efficiency, and versatility, making it a preferred choice across a wide range of industrial and automotive applications.

Design and Construction

The SKF 6217 is a single row deep groove ball bearing, featuring a simple yet robust design. It consists of an inner ring, an outer ring, a cage, and a set of precision steel balls. The deep raceway grooves in both rings allow the bearing to support radial loads and moderate axial loads in both directions. This dual-load capability enhances its versatility and makes it suitable for various dynamic and static applications.

The bearing is manufactured using high-grade bearing steel, ensuring excellent hardness, wear resistance, and fatigue life. The cage is typically made from pressed steel, which provides strength and stability while maintaining a lightweight profile.
