Thin section bearings, also known as thin wall bearings or constant cross-section bearings, are a special type of rolling bearings with extremely thin wall thickness. Different from standard bearings, they maintain the same cross-section size even when the bore diameter increases greatly, which helps equipment designers save installation space and reduce overall weight.

Constant cross-section thin section bearings are usually divided into radial contact type, angular contact type and four-point contact type. Four-point contact thin section bearings can bear radial load, axial load and overturning torque at the same time, making them the preferred choice for compact robotic joints, optical testing equipment and precision turntables.

In industrial robot projects, lightweight design is very important. Traditional thick bearings will increase the inertia of moving parts. High-precision thin section bearings effectively solve this pain point. Lanbo Bearings produces a full range of thin wall bearings including 61800, 61900 series and KA, KB, KC series constant cross-section bearings. Our products feature low friction, high rotational accuracy and long service life.
