All products

7310 Series High-capacity Angular Contact Ball Bearing | 10°–40° Contact Angle

The 7310 Series is a robust and high-capacity Angular Contact Ball Bearing designed to sustain significant combined radial and axial loads in one direction. With contact angles ranging from 15° to 40°, it is engineered for demanding applications that require high rigidity, precise shaft positioning, and reliable performance under heavy loads and moderate speeds, making it ideal for industrial gearboxes, large pumps, and heavy-duty machinery.

7300 Series Angular Contact Ball Bearing Single Row For Robust Industrial Machinery | 10–35mm Bore Range

The 7300 Series is a heavy-duty Angular Contact Ball Bearing engineered to withstand high combined radial and axial loads in demanding operating conditions. Featuring selectable contact angles, it provides reliable shaft positioning, operational stability, and long service life in applications such as industrial gearboxes, agricultural equipment, and heavy power transmission systems.

7306 B Series Angular Contact Ball Bearing | 40° Contact Angle for Maximum Axial Rigidity

The 7306 B Series is a specialized Angular Contact Ball Bearing, defined by its steep 40° contact angle (B design), engineered to withstand exceptionally high axial (thrust) loads. This design prioritizes supreme axial stiffness and minimal shaft displacement under heavy thrust conditions. It is an optimal solution for precision applications where axial load dominance requires maximum rigidity and stability, such as in heavy-duty machine tool components, high-thrust gearboxes, and industrial pump systems.

7309 Series Angular Contact Ball Bearing | 15°-40° Contact Angle | Heavy-Duty Design

The 7309 Series is a heavy-duty Angular Contact Ball Bearing engineered to handle substantial combined radial and axial loads. Providing selectable contact angles to meet specific application demands, this series is built for high rigidity, reliable performance under significant stress, and durable operation in tough industrial settings. It is a robust and dependable choice for demanding applications such as industrial gearboxes, heavy pump systems, and power transmission units.
