Yrt Turntable Bearing are 4 point contact thin section type ball bearings that have holes in both the inner and outer rings for easy mounting.   These products were designed from standard thin section bearing geometry.  We just reduced the ID and increase the OD to accommondate bolt holes.  Our intention was to make the bearing easy to mount in an industrial application.  One that would require no additional machining (i.e., turning or grinding) of mating components for proper installation.

 Bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
