Short technical articles in digital library

The TechTalk Design Advice Series at is a regularly updated library of information on several power-transmission issues and components. The latest entry details slewing-ring bearings.

Here's an excerpt:

Sliding slewing ring bearings are … lubrication-free … they won't contaminate environments or seize in applications with dirt or dust, unlike roller bearings. The plastic sliding elements and hard anodized-aluminum finish possess low moisture absorption and corrosion-resistance, and so require no cover or seal. Sliding slewing ring bearings can also be used in medical and lab equipment, solar panels, food processing …
