Introduction
Timken Super Precision specializes in the development of thin-section, high-precision ball bearings for aerospace and instrument applications. These bearings range from 0.625” to 12” in outer diameter and are available in all ABEC classes. They offer advantages such as greater stiffness, lower torque, and reduced weight and space compared to standard bearings.

Specifications
The bearings are made from high-quality materials like 440C stainless steel and 52100 alloys. They come with various spacer options and shield or seal configurations to optimize performance. The catalog covers Torque Tube bearings and Thin-Section bearings with cross sections from 1/8” to 5/16” and outer diameters up to 4.5”. Larger bearings up to 12” OD are also available.

Design Configurations
1. Conrad Assembly: Suitable for average-speed, multi-directional, moderate-load applications.
2. Angular Contact: Offers high thrust capacity for uni-directional loads and is well-suited for preloaded pairs.
3. Fractured Race: Allows greater multi-directional loads and speeds, accommodating thrust or moment loads.

Engineering Data
Includes information on materials, retainers, shields and seals, radial play, tolerances, lubrication, and loading rates. Preload, deflection, and torque are also discussed to ensure optimal performance.

Special Designs
Timken offers special design configurations and solutions for unique application problems, including miniature bearings as small as 0.059” OD.

Global Presence
Timken operates manufacturing divisions and sales offices worldwide, including in the USA, Europe, and Asia, providing a wide range of bearing products for various industries.
