High Load 7002AC 15x32x9mm Angular Contact Ball Bearing

Product Overview：

When your machinery demands reliable performance under combined radial and axial loads, the 7002AC angular contact ball bearing delivers exceptional capability in a compact 15x32x9mm envelope. Manufactured from high-carbon chromium bearing steel (GCr15) and featuring a precision 25° contact angle, this single-row bearing is engineered for applications where load direction and rotational speed both matter.

Key Features:

• Combined Radial and Axial Load Capacity
  Unlike deep groove ball bearings that are primarily radial-load devices, the 7002AC is specifically engineered to handle simultaneous radial and axial loads. This capability reduces the number of bearings required in an assembly and simplifies mechanical design.

• High-Speed Capability
  The 7002AC is engineered for high-speed operation, with grease-lubricated limiting speeds of 19,000–26,000 RPM and oil-lubricated speeds up to 32,000 RPM, depending on cage and lubrication configuration. This speed capability makes it suitable for high-frequency motors and precision spindles.

• High Rigidity Under Preload
  When properly preloaded, angular contact bearings provide significantly higher stiffness than deep groove bearings. The preload eliminates internal clearance, ensuring precise component positioning and minimal deflection under load—critical for machine tool spindles and precision positioning systems.

• Wide Precision Grade Availability
  The 7002AC is available in multiple precision grades—P0 (standard), P6, P5, and P4 (ABEC-7) —allowing engineers to select the accuracy level that matches their application requirements.

• Versatile Sealing Options
  Available in open, ZZ (double metal shielded), and 2RS (double rubber sealed) configurations, the 7002AC can be tailored to specific environmental requirements.
