7036 ACDGA/P4A Bearing Product Overview & Core Advantages
The 7036 ACDGA/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This single bearing features an extra light preload (Class A) and a 25° contact angle, optimized to handle combined radial and axial loads simultaneously. Manufactured to the stringent P4A tolerance class, it delivers superior running accuracy, high rigidity, and reliable operation in high-speed environments up to 16,250 rpm. Its universal matching designation (SU) allows for flexible mounting in pre-adjusted sets, making it an ideal choice for precision spindles and other critical machinery components.
