Double row: 32xx; 33xx (52xx, 53xx)

Advantage:

Multi-directional load capacity: Capable of simultaneously withstanding radial and unidirectional axial loads, suitable for complex stress conditions.

High rigidity and high precision: The structural design provides high rigidity, which can be further enhanced through preload, maintaining rotational stability and repeatability.

High-speed performance: Optimized design and contact angle (e.g., 15°) reduce friction and temperature rise, enabling operation at higher speeds.

Adjustable contact angle: The contact angle can be adjusted as needed (e.g., 15°, 25°, 40°) to balance speed, precision, and axial load capacity.

Easy installation and adjustment: The inner and outer rings are separable for easy installation and preload adjustment.

Low friction and long life: Excellent lubrication and design reduce friction and wear, extending component life.

Wide applications: Suitable for various precision and heavy-duty equipment such as machine tools, motors, pumps, and robots.
