💡 What is a slewing ring bearing used for in heavy equipment?

In general, it's a single, compact bearing that supports rotation under heavy loads while allowing a platform to turn smoothly.

- Handy in cranes, wind turbines, and large turntables - Keeps radial and axial loads stable while allowing slow rotation - Works with outside gear configurations for direct gear engagement - Requires proper lubrication and sealing for longevity

Douille à billes à quatre points de contact avec engrenage extérieur

Une couronne d'orientation est un roulement qui supporte généralement une charge lourde mais à rotation ou oscillation lente, souvent une plate-forme horizontale telle qu'une grue conventionnelle ou la plate-forme orientée vers le vent d'une éolienne à axe horizontal. (Le terme "slew" signifie tourner sans changer de place).
