01. Effective Non-Contact Shielding

Two pressed steel shields (ZZ) provide reliable defense against dust and dry debris without adding significant rotational torque, making this bearing ideal for high-speed applications.

02. Space-Saving Ultra-Thin Construction

With a width of only 7 mm, this bearing offers a significant reduction in axial space and weight, enabling more compact and efficient designs in portable and miniaturized equipment.

03. High-Speed & Low-Friction Design

Precision-manufactured from chrome steel with optimized internal clearances, the 6902-ZZ ensures stable operation, minimal heat buildup, and extended service life at elevated speeds.

• SKF: 6902-ZZ
• NSK: 6902ZZ
• FAG: 6902-ZZ
• NTN: 6902LLU
• KOYO: 6902LLB

Design & Configuration

The 6902-ZZ is supplied with standard double steel shields, offering effective non-contact protection in clean, dry, or lightly dusty conditions. For applications exposed to moisture or requiring more robust sealing, the double rubber-sealed version (6902-2RS) is recommended.

"An optimal choice for high-speed small motors, precision instruments, and compact drives where a slim profile, dust protection, and reliable performance are critical."
