2344/2347 Double-way Thrust Angular Contact Ball Bearing

The 2344/2347 series double-way thrust angular contact ball bearings are high-precision bearings capable of simultaneously supporting radial loads and bidirectional axial loads, while restraining bidirectional axial shaft displacement. Key features include:
Precision Design: Preloading minimizes internal clearance, achieving P4/P2 rotational accuracy for precise positioning.
Lightweight & Compact: Optimized structure reduces installation space while supporting high-speed rotation.
Durable Materials: Manufactured with high-carbon chromium bearing steel for wear resistance and long service life.
Structural Features
Dual-row Balls: Two rows of balls arranged at specific angles enhance axial load capacity.
Split Components: Composed of two shaft rings, one housing ring, one spacer, and a cage. Grinding the spacer thickness allows precise adjustment of clearance or preload.
Contact Angle Design: Typically 60°, optimizing axial force distribution for enhanced rigidity and rotational precision.

Selection Criteria

  1. Preload Method: Choose preload force based on load requirements to balance rigidity and lifespan.
  2. Speed Limits: High-speed applications require optimized cage materials (e.g., phenolic resin) and lubrication.
  3. Mounting Configurations: Flanged, press-fit, or expansion sleeve types adapt to diverse installation spaces.
  4. Environmental Compatibility: Select stainless steel or ceramic materials for high-temperature, vacuum, or corrosive environments.
  5. Precision Classes: P4/P2 for precision machine tools; P5 for general industrial equipment.

Note: During installation, avoid applying primary axial loads through the single-side ball-loading gap to ensure stable bearing performance.
