7040 CD/P4A

The 7040 CD/P4A is a super-precision angular contact ball bearing meticulously designed for applications demanding the highest levels of accuracy and performance. It features a 15° contact angle and a single-row, universally matchable design, allowing it to effectively handle simultaneous radial and axial loads that act in one direction. Manufactured to the stringent P4A tolerance class, this bearing exhibits exceptional running accuracy, minimal vibration, and remarkable stiffness, making it indispensable for high-speed, precision-critical operations. Its robust construction ensures reliability even under heavy loads and moderate operating temperatures, contributing to a longer operational lifespan.

The advantages of incorporating the 7040 CD/P4A are significant for high-performance machinery. Its ultra-high running accuracy and load-carrying capacity translate directly into enhanced machine tool performance, improved part quality, and increased productivity. The universally matchable design simplifies mounting arrangements, allowing for precise load sharing and controlled preload without complex adjustments. This precision, combined with low heat generation and low noise levels, ensures stable operation and reduces wear on adjacent components, ultimately leading to reduced maintenance costs and extended equipment service life in demanding sectors like aerospace, machine tools, and high-speed industrial equipment.
