S7013 ACDGB/HCP4A Bearing Product Overview & Core Advantages
The S7013 ACDGB/HCP4A is a single-row angular contact ball bearing engineered for ultra-high precision and high-speed operation. Positioned in the P4A super-precision tolerance class, it delivers exceptional rotational accuracy and dimensional stability. A key feature is its universal matchable (SU) design, allowing bearings to be flexibly paired in various preloaded configurations. The combination of a ceramic ball material and phenolic cage significantly enhances its performance in demanding applications, offering superior speed capability, rigidity, and extended service life.
Model Code Breakdown

S7013 ACDGB/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The use of ceramic balls with steel rings results in lower density, reduced centrifugal force, and superior electrical insulation. This directly contributes to a higher limiting speed (31,000 rpm), lower operating temperature, and extended lubrication life.
Phenolic Resin Cage: The lightweight and robust phenolic cage is ideal for high-speed applications, offering excellent dimensional stability and low friction under high centrifugal forces.
Universal Matchability & Preload: The DGB suffix indicates a Light preload (Class B) and universal matching. This allows for simplified assembly of bearing sets (up to 4 in a set) to achieve precise, pre-adjusted system stiffness and minimal runout.
High Load Capacity: With a 25° contact angle and premium materials, this bearing is designed to handle significant combined radial and axial loads simultaneously, ensuring reliable performance under complex loading conditions.
