Double Angular Contact Arrangement：The 2347 Series Double Angular Contact Thrust Ball Bearings feature a meticulously designed double-row structure. The two rows of rolling elements are symmetrically distributed, each forming a precise contact angle, with the corresponding raceway. This unique configuration enables it to outstandingly handle bidirectional axial thrusts and ensure the stable operation of equipment under complex force conditions.
High-quality Component Fabrication：The rolling elements are made of top-grade steel and have undergone fine grinding, with a mirror-like smooth surface and the dimensional accuracy strictly controlled to the micrometer level, fitting tightly with the raceway to effectively reduce friction losses; the rings are forged and processed through multiple complex processes from high-strength alloys, possessing impeccable roundness, cylindricity and surface hardness, providing a solid support for the rolling elements.
Adaptable Cage：The cage selects high-strength engineering plastics or alloy materials based on the movement characteristics of the rolling elements. The structural design is optimized exquisitely. It can methodically guide the cyclic movement of the rolling elements, prevent collisions between them and also adapt to high-speed operation to maintain dynamic balance.
Superior Axial Load-bearing：Thanks to the ingenious double-row architecture and reasonable contact angle, it has outstanding axial load-bearing capacity. It shines in fields such as hydro turbines in large water conservancy hubs, generators in thermal power stations and machine tool spindles in heavy mechanical processing, calmly bearing huge axial forces.
High-speed Smooth Operation：The precise cooperation of components results in minimal vibration and almost no noise during operation, perfectly meeting the stringent requirements of speed and stability for high-speed cutting machine tools and high-speed rotating equipment, significantly improving operating efficiency.
Precise Axial Positioning：Each component is inherently of high precision, ensuring accurate axial positioning, providing a reliable guarantee for precision machining and measuring equipment, helping the high-end manufacturing field to achieve ultimate precision.

Application

The bearings can be used in the following industries

Energy and Power：In the critical thrust bearing positions of hydro turbines and generators, it stably bears the massive axial forces generated by water flow impact and electromagnetic forces, safeguarding efficient energy conversion and transmission.
Heavy Manufacturing：As the mainstay of the spindles of core equipment such as heavy machine tools and large rolling mills, it helps to overcome the difficulties of high-precision and large-load machining and drives the mechanical manufacturing to a higher level.
Precision Engineering：Used in the axial positioning hubs of precision instruments such as high-precision grinding machines and coordinate measuring machines, it meets the requirements of high precision and stable transmission for microscopic manipulation, empowering scientific research and detection work to reach new heights.
