7000 ACE/HCP4A Bearing Product Overview & Core Advantages
The 7000 ACE/HCP4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional speed capabilities and rigidity. This metric series bearing features a 25° contact angle optimized for handling combined radial and axial loads in one direction. Manufactured to P4 (ABEC-7) tolerance class, it delivers superior running accuracy and positional stability. The combination of ceramic balls and phenolic cage enables outstanding high-speed performance up to 150,000 rpm, while the available preload ensures minimal deflection under operational stresses.
