Product catalog summary
Overview: The document is a comprehensive product catalog for Smith Bearing®, a division of Accurate Bushing Company, specializing in precision needle roller bearings for aerospace and industrial applications. It highlights the company's commitment to accuracy and quality, detailing various products, specifications, and applications.
Product Range: The catalog features a wide range of precision bearings, including Cam Follower Needle Roller Bearings in both inch and metric sizes, stainless steel options for corrosive environments, and self-lubricating engineered plastic bushings. The Smith-Trax® series includes tapered roller bearings and deep-groove ball bearings for high-thrust load applications. Aerospace and military-approved needle roller bearings are also highlighted for engine and airframe applications.
Specifications and Features: The catalog details various types of bearings, such as Cam Followers available in stud and yoke types, Smith-Trax® Track Rollers designed for high radial and axial loads, and custom-engineered special assemblies. It emphasizes the use of high-quality materials like bearing steel and corrosion-resistant stainless steel.
Applications: Bearings are used in aerospace applications such as thrust reversers, afterburners, divergent nozzles, flap-tracks, canopies, and landing gear. Non-metallic bushings are mentioned for self-lubricated applications.
Quality and Standards: Smith Bearing® is ISO 9001 and AS 9100 registered, ensuring high-quality manufacturing standards. The bearings meet military and aerospace specifications, including AS-39901.
Distribution and Support: The company serves a global market with a network of distributors, manufacturing plants, and sales offices, providing personalized customer service and cost-effective products.
Contact Information: Contact details for corporate headquarters and customer service are provided, emphasizing the company's readiness to assist with custom manufacturing and product inquiries.
Engineering Capabilities: Smith Bearing® offers advanced CNC grinding and precision machining centers, collaborating with OEMs to provide custom solutions using a wide range of materials, including high-carbon alloy steels and exotic alloys.
Specifications and Procedures: Detailed instructions on the installation and lubrication of cam followers are provided, emphasizing the importance of correct bore sizes and central pressure application during installation. The document also outlines the re-lubrication process using Alemite fittings.
Bearing Life and Load Calculations: The concept of bearing life, particularly the L10 life, is explained, with formulas for calculating life expectancy and the Basic Dynamic Rating (BDR) for specific applications.
Track Capacity and Shock Load: Track capacity is discussed in terms of maximum load without deformation, with tables for determining capacities based on track hardness and tensile strength. Adjustments for shock loads are recommended based on load classification.
High Temperature Applications: Standard bearings lose load rating at elevated temperatures, with suggestions for using exotic alloys for high-temperature applications. A temperature chart shows the effect of temperature on load ratings for different materials.
Tolerance and Size Charts: Tolerance charts for metric bearings are included, detailing maximum and minimum sizes for components like cylindrical roller diameter and stud diameter.
Conclusion: The document serves as a comprehensive guide for selecting, installing, and maintaining cam followers and yoke rollers, focusing on optimizing bearing life and performance through proper mounting, lubrication, and load management.
Military Qualifications: Bearings meet SAE AS 39901 military requirements and are often pre-lubricated to meet OEM requirements. They comply with Federal Aviation Regulations for Parts Manufacturing Approval.
Bearing Selection: Various series like YAF, YAT, YAD, YAS, and YAG are designed for specific applications, with features like corrosion protection and re-lubrication capability.
Load Ratings: Aircraft Static Capacity (ASC), Limit Load Rating, and Ultimate Static Fracture Load Rating are defined, with specific values provided for different series.
Temperature and Material: Unsealed bearings can operate up to 400°F, while sealed bearings are limited to 250°F. Stainless steel bearings are available with high strength and corrosion resistance.
Model Descriptions and Standards: Various bearing models and their compliance with standards like AS, MS, and NAS are listed, with detailed dimensional data provided.
Interchange Tables: Interchange tables list equivalent part numbers across different manufacturers, facilitating cross-referencing and compatibility checks.
Drill Jig Bushings: Detailed specifications and pricing for drill jig bushings are provided, including types like headless press-fit and head press-fit, with dimensions, ANSI standards, and pricing codes.
Cam Followers: Specifications for needle roller yoke type and stud type cam followers are included, with compatibility information for brands like McGill, RBC, and Torrington.
Miscellaneous Hardware: Information on lock screws, round clamps, extended range bushings, and oil groove applications for lubrication is provided.
