6802-ZZ Shielded Deep Groove Ball Bearing for High-Speed Compact Designs | 15×24×5 Mm

The 6802-ZZ is a Double Metal-Shielded, Extra-Thin Series Deep Groove Ball Bearing designed for applications requiring high-speed capability and basic contamination protection in a minimal axial space. Equipped with two pressed steel shields (ZZ), it effectively guards against larger dust particles and debris while maintaining low internal friction. With a 15 mm bore and an ultra-slim 5 mm width, this bearing is an optimal choice for precision mechanisms where space is limited and lower torque is preferred over full sealing.



6802-ZZ Deep Groove Ball Bearing 15×24×5 mm | ISO 68 Series – Extra Thin | Double Metal Shielded

Featuring a precision-engineered deep groove raceway, this shielded bearing enables smooth and efficient operation at speeds up to 26,000 r/min (Oil). It is constructed to accommodate moderate radial loads and is suitable for light axial loads, providing a reliable, low-maintenance solution for high-speed and dry or lightly contaminated environments.

Key Performance Features

01. Precision-Ground for Smooth High-Speed Running

Manufactured from high-carbon chromium steel with precision-ground surfaces, the 6802-ZZ ensures minimal vibration and stable operation at elevated speeds..

02. Ultra-Low Cross-Section for Maximum Space Savings

With a width of only 5 mm, this bearing allows for extremely compact design solutions without sacrificing performance, ideal where axial space is at a premium.

03. Steel Shields for High-Speed Operation

The two non-contact metal shields (ZZ) provide protection from large particulates and allow for higher rotational speeds and lower running torque compared to contact seals.

Design & Configuration

The 6802-ZZ is furnished with double metal shields as standard, making it the preferred choice for high-speed applications or environments where lower starting torque is critical and only light dry contaminants are present. For applications requiring protection against moisture or fine dust, the double rubber-sealed variant (6802-2RS) is recommended.

"The 6802-ZZ is an excellent solution for designers seeking an ultra-thin, high-speed bearing that offers basic protection with minimal friction for compact, precision devices."
