7036 ACD/HCP4A Bearing Product Overview & Core Advantages
The 7036 ACD/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This single-row bearing is distinguished by its 25° contact angle and P4 (ABEC-7) tolerance class, ensuring superior running accuracy. A key advantage is its ability to accommodate high combined loads, particularly thrust loads in one direction. The combination of a phenolic resin cage, ceramic balls, and factory-applied lubrication enables outstanding high-speed performance and operational stability, making it an ideal solution for high-reliability machinery.
