SDP/SI offers a hub of engineering resources. Accurate, informed educational content and technical guides are a substantial part of our mission in building better engineers and setting innovation into motion.
Careers in engineering and design can be all-consuming, especially when problems arise requiring custom solutions. Access to the right information and tools is critical for engineers and designers to deliver quality results while maintaining a healthy balance between work and everyday living. That’s why we built an online library—for helping our people find all the help they need to succeed.
Learn about precision metal ball bearings and plastic bearings for industrial and commercial applications. Start with an introduction and brief overview of bearing types, and read about selection factors to consider such as loads, bearing reactions, tolerances and clearances, etc.
Check out the design data we have on ball bearings, from lubrication and surface finishes to porous metal and plastic materials. Review these tables to consider which bearing will best fit the application it is intended for, as well as what lubrication is correct and available.

Plastic and Non-Metallic Bearings
Porous Metallic Bearings
Our resources on timing belts provide an overview of belt designs along with installation guidelines and operations. GT®3 timing belts offer an improved construction and material compound for superior load bearing capacity. Belt tensioning force and minimum pulley diameter specifications are also listed in easy-to-follow tables. Belt drives are particularly useful in applications where layout flexibility is important. Belt drives enable the designer to place components in more advantageous locations.
