Overview: Aurora Bearing Company, founded in 1971, is a prominent manufacturer of rod ends, spherical bearings, and journal bushings, known for its quality across design, marketing, engineering, and manufacturing. By the 1980s, it had entered the aerospace market, gaining recognition in the aircraft airframe industry.

Product Offerings: The company produces standard and special spherical bearings, rod ends, and bushings for aerospace applications, including ultra-light aircraft, general aviation, commercial jet liners, military aircraft, and space applications like the International Space Station.

Quality Assurance: Aurora Bearing's quality system, ABC-9000, is rigorously reviewed by aerospace customers, ensuring total traceability from manufacturing to shipping.

Military Approved Bearings: Products such as the AT3200 PTFE Liner System are approved to military specifications like SAE-AS81820 and SAE-AS81935, manufactured under strict quality and SPC systems.

General Purpose Bearings: Bearings and rod ends for general aviation and non-critical commercial aircraft applications adhere to stringent quality requirements.

Engineering Information: The catalog includes engineering information for aircraft designers, with additional support from Aurora's engineering department.

Specifications: Detailed specifications for products include material composition, heat treatment, plating, and liner systems, qualified under relevant SAE standards.

Procedures and Standards: Threads conform to UNJF-3B per MIL-S-8879, with bearings qualified under various SAE standards. No-load rotational breakaway torque can be adjusted for specific applications.

Recommendations: Consultation with the factory is recommended for material substitutions or dimensional modifications, wider temperature ranges, and additional staking groove and assembly information.

Data Summary: Tables list dimensions, load capacities, and part numbers for bearings, with key parameters like ultimate static radial load and fatigue load.

Critical Information: Bearings are available in plain and grooved series, with specific fit requirements for low torque applications. Standard fit bearings lack radial or axial clearance.

Staking Procedure: A trial stake assembly determines necessary staking force, with pressure applied in multiple rotations for uniformity.

Liner Design Specifications: Various PTFE liner systems are detailed, with specifications on thickness, temperature range, static limit load, and stiffness.

Performance and Capabilities: Bearings are suitable for various loads and speeds, with excellent stick-slip properties.

Major Specification Approvals: Includes military, Boeing, Airbus, and Lockheed specifications.

Conversion Factors: Provides conversion factors for force, length, weight, and temperature.
