GATES 7308A Angular Contact Ball Bearing | 40x90x23mm | High-Speed Spindle Grade

The GATES 73XXA series angular contact ball bearing (specifically the 7308A, 40x90x23mm) is engineered for high-precision applications requiring optimal stiffness and superior speed performance. Featuring a 30-degree nominal contact angle, this single-row design is uniquely suited to accommodate substantial radial loads simultaneously with significant axial loads acting in one direction. Its robust internal geometry, coupled with high-precision tolerance grades (P5 or better), minimizes friction and heat generation, making it indispensable for machinery operating under demanding cycles. Standard fit includes either a pressed steel or phenolic resin cage, ensuring reliability across varied temperature and lubrication schemes. Selecting the GATES 73XXA bearing guarantees maximum operational stability and reduced lifetime maintenance costs in critical machinery. Ideal for integration into high-speed gearboxes, industrial pumps, hydraulic motors, and precision machine tool spindles, this bearing ensures precise shaft guidance and outstanding rigidity. Its ability to support high combined loads extends the life of adjacent components, while the optimized raceway finish promotes quiet, vibration-free operation. Trust GATES engineering for applications where reliability and rotational accuracy are non-negotiable standards.

Key Features

  • High-Speed Capability: Optimized internal design facilitates extremely high rotational speeds suitable for spindle applications.
  • Unidirectional Axial Load Support: Designed to efficiently carry high combined radial and single-direction axial loads.
  • 30 Degree Contact Angle: Offers an optimal balance between axial rigidity and high-speed operation.
  • High Precision Grade: Manufactured to P5 (or better) tolerances for minimized runout and enhanced rigidity.
  • Single Row Design: Compact profile suitable for installations requiring high load capacity in minimal space.
  • Separable Components (Non-standard dependent on closure): Allows for separate mounting of the inner and outer rings, simplifying complex installations.
