Gimbal bearings, also known as self-aligning bearings, are highly versatile bearings that enable smooth and reliable rotation even in demanding conditions. They stand for approximately 80% of all bearing sales worldwide, highlighting their extensive use across a wide range of industries.
What are Gimbal Bearings?
Gimbal bearings are a unique type of bearing consisting of an outer ring, an inner ring, and a set of rolling elements that are contained within a spherical housing. This specialized design allows for three axes of rotation, enabling precise and flexible movement.
How Gimbal Bearings Work
The rolling elements in a gimbal bearing are free to move within the spherical housing. When a load is applied, the bearing's unique design allows the inner and outer rings to adjust their alignment automatically, ensuring that the load is distributed evenly across the rolling elements. This ability to self-align provides significant advantages in applications where misalignment or tilting is inevitable.
