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.

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.”
