Key Performance Features

01. Single‑Shield Protection

The non‑contact steel shield on one side provides effective defense against larger dust and particles in demanding conditions. It helps retain internal lubrication while maintaining very low friction, offering a balanced solution for applications where minimal drag is prioritized.

02. High Load Capacity (Light Series)

Designed within the light series, this bearing delivers strong radial load support (Dynamic: 4.05 kN) within a compact form. Its universal deep‑groove geometry also accommodates moderate axial loads from both directions, ensuring versatility in varied mechanical layouts.

03. Precision High‑Speed Performance

Manufactured to standard industrial tolerances and available in precision grades up to P5. Optimized internal geometry reduces friction and heat build‑up, enabling smooth, accurate rotation at high speeds with excellent rigidity and running stability.
