Product structure:

The F684 ZZ bearing is a miniature deep groove ball bearing with a bore diameter of 4 mm, outer diameter of 9 mm, and width of 4 mm. It is constructed with stainless steel material, dual-sided metal dust covers (ZZ shield), and an open-style deep groove design for smooth ball circulation.

Key performance features:

It features high precision, low noise, and stable operation. The stainless steel material provides corrosion resistance, while the dual dust covers effectively prevent contamination. It supports moderate speeds and loads, requires minimal maintenance, and offers long service life.

Main application scenarios:

Commonly used in small drive motors, cooling fans, precision optical devices, model toys, measurement tools, and rotating components of household appliances.

Technical Specifications and Requirements:

The bearing meets ISO 9001 and ABEC-1 precision standards. It operates within a temperature range of -30°C to 120°C, with a dynamic load capacity of 0.38 kN and static load capacity of 0.12 kN. Proper installation should avoid excessive axial or radial force, and it should be stored in a dry, dust-free environment.
