01. Dual‑Shield Contamination Defense

Double non‑contact steel shields provide robust two‑side protection against dust and larger particulates in challenging environments. This configuration effectively seals in grease for extended service life while ensuring minimal rotational friction and low operating torque.

02. Enhanced Load Support (Light Series)

Built to the light series standard in a compact 6×19×6 mm envelope, this bearing offers increased radial load capacity. The universal deep‑groove design also reliably handles moderate axial loads from either direction, making it suitable for applications requiring both strength and compact dimensions.

03. Smooth High‑Speed Operation

Produced to consistent industrial tolerances with availability up to P5 precision grades. Its refined internal geometry minimizes friction and heat generation, supporting exceptional rotational accuracy, smoothness, and reliable performance even under high‑speed conditions.

• SKF: 626-2Z
• NSK: 626 ZZ
• FAG: 626 ZZ
• NMB: R-1960ZZ
• NTN: 626ZZ

Design & Configuration

The 626-ZZ is equipped with double pressed steel shields as standard, offering superior internal protection compared to the single-shielded Z variant. For applications requiring complete sealing against moisture or very fine dust, configurations with double low-friction rubber contact seals (626-2RS) are also available.

"The 626-ZZ is the recommended choice for high-speed applications where dust is a concern but minimal friction must be maintained."
