01. Axial Load Capacity & Rigidity

With defined contact angles (15°, 25°, or 40°), the 7000 Series provides superior axial load support and shaft rigidity compared to deep groove bearings. This makes it ideal for applications where axial displacement must be minimized.

02. High-Speed & Precision Operation

Manufactured to tight tolerances (available up to P4 precision grade), these bearings offer low vibration and high running accuracy. Suitable for high-speed spindles, motors, and precision gearboxes.

03. Versatile Mounting & Configuration

Can be mounted singly, in pairs, or in tandem to accommodate different load directions and stiffness requirements. Optional shields (ZZ) or seals (2RS) provide flexibility for various environmental conditions.

• FAG: 7000 C, 7000 AC
• NTN: 7000C, 7000AC

Design & Configuration

The 7000 Series is commonly supplied with open designs for easier lubrication access, or with non-contact shields (ZZ) for basic contamination protection. For applications requiring sealed and pre-greased solutions, contact rubber seals (2RS) are available. Various contact angles (C=15°, AC=25°, B=40°) allow selection based on axial load capacity and rigidity requirements.

"For high-precision applications such as machine tool spindles or pump shafts, the 7000 AC (25° contact angle) provides an optimal balance of axial rigidity and speed capability.”
