01. Ultra-High-Speed Capabilities

Manufactured with strict dimensional tolerances (Standard P0 / P5 available), the 683-ZZ utilizes finely polished raceways and a low-friction steel cage. This internal geometry drastically reduces rotational resistance, allowing the bearing to operate quietly and smoothly at speeds up to 58,000 RPM without overheating.

02. Dual Metal Shields (ZZ) for Protection

Equipped with pressed steel shields on both sides, this model offers excellent defense against particulate contamination. The non-contact shield design ensures there is no added friction torque, making it the superior choice for environments where maintenance access is difficult and high-speed efficiency is required.

03. Optimized for Micro-Scale Load Distribution

Despite its ultra-compact 68 Series dimensions (3×7×3 mm), the 683-ZZ provides a stable dynamic load rating of 0.311 kN. The high-quality GCr15 chrome steel construction ensures it withstands continuous rotational stress, resisting wear and deformation in continuous-duty miniature applications.

Design & Configuration

The 683-ZZ is factory-supplied with dual metal shields (ZZ) and pre-lubricated with high-performance grease, providing a ready-to-mount solution for dust-prone, high-speed applications. If your assembly requires protection against liquid ingress rather than just dry contaminants, this model can be customized with rubber contact seals (683-2RS). For extreme high-speed or ultra-low friction needs, open variants (683) without shields are also available.
