What is a Slewing Bearing Without Gear?

A slewing bearing without gear is a specialized rotational component designed for smooth, low-friction movement in machinery. Unlike geared variants, these bearings rely on raceway geometry and rolling elements to facilitate rotation, making them ideal for applications where precise motion control isn’t gear-dependent.

Key Design Features

These bearings typically incorporate four-point contact balls or crossed rollers, offering high load capacity and rigidity. The absence of external gearing simplifies installation and reduces maintenance needs, while premium materials like hardened steel ensure durability in demanding environments.

Common Applications

From medical imaging devices to solar tracking systems, slewing bearing without gear units provide reliable performance. They’re also widely used in robotics, packaging machinery, and light-duty industrial rotators where compact design and efficiency are prioritized.

Frequently Asked Questions

How does a gearless slewing bearing differ from a geared version?

Gearless types eliminate external teeth, reducing complexity and cost while maintaining core rotational functionality. They excel in applications not requiring torque transmission via gearing.

What maintenance do they require?

Regular lubrication and inspection for wear or contamination are essential. Their simplified design often means longer service intervals compared to geared alternatives.
