71822 ACD/P4

The 71822 ACD/P4 is a super-precision angular contact ball bearing engineered for machinery that demands the highest levels of rotational accuracy and speed. This bearing belongs to the extremely thin 718 series, making it ideal for applications with severe space constraints. The "ACD" designation indicates a 25-degree contact angle, a design optimized for supporting combined radial and axial loads with a high degree of rigidity. Critically, the "P4" suffix signifies its adherence to extremely tight dimensional and running accuracy tolerances, conforming to ISO tolerance class 4. This level of precision is achieved through the use of high-purity steel and advanced manufacturing processes, ensuring exceptional performance under the most demanding conditions.

The primary advantage of the 71822 ACD/P4 lies in its superior performance characteristics, which directly translate to enhanced machine efficiency and product quality. Its high-precision design minimizes friction and heat generation, allowing for higher operational speeds and extending service life. The bearing's rigidity ensures minimal shaft deflection, which is crucial for applications like machine tool spindles, robotics, and precision measuring instruments where accuracy is paramount. By providing unparalleled rotational stability and reliability, this bearing enables machinery to operate faster, more accurately, and for longer periods, delivering a significant return on investment through improved productivity and reduced maintenance.
