SKF Launches Precision Thinwalled Bearings for Highdemand Applications

In precision instruments where space constraints are critical and every component's dimensions must be exact, even minor deviations in bearing size can significantly impact overall system performance. The SKF 6804 thin-wall deep groove ball bearing is engineered specifically to meet these challenges, offering exceptional performance and sophisticated design that makes it an ideal choice for numerous precision applications.

The SKF 6804 is an open-type thin-wall deep groove ball bearing distinguished by its slender cross-section design. This innovative construction provides reliable rotational support within extremely limited spaces. With dimensions of 20mm × 32mm × 7mm (inner diameter × outer diameter × width), this compact bearing is particularly suited for applications requiring lightweight and miniaturized components, including robotics, medical equipment, aerospace systems, and precision instruments.

Manufactured from high-quality bearing steel, the SKF 6804 ensures superior strength, wear resistance, and fatigue durability. The steel cage further enhances the bearing's durability and reliability, maintaining stable performance even under high-speed operation. The open design facilitates direct lubrication, promoting heat dissipation and extending service life. Standard radial internal clearance guarantees optimal performance across varying operating temperatures.

The SKF 6804 boasts a dynamic load rating of 4.03 kN and static load rating of 2.32 kN, with a fatigue load limit of 0.104 kN. These specifications demonstrate the bearing's capacity to handle both radial and axial loads across diverse applications. With a reference speed rating of 45,000 rpm and a limiting speed rating of 28,000 rpm, this bearing is well-equipped for high-speed operational requirements.

The SKF 6804 thin-wall deep groove ball bearing finds extensive use across multiple industries:
