Robotic Bearings - Bearings in Automation | AST Bearings

Single-row deep groove ball bearings, with sizes ranging from miniature to extra-large, are generally the go-to bearing choice for the majority of robotic and automation appliions. Thin section bearings are often designed into robot arm joints due to their low mass, space-saving construction and high-speed capability.

Slewing Bearings | inno

The slewing bearing is the same as the ordinary bearing, it is asseled by rings and rollers. However, compared with ordinary bearings, slewing bearings have many differences. Generally, the size of the slewing bearing is very large, and the outer diameter is usually between 0.4m and 10m, and some even between 40m.
