This zinc-plated lazy susan turntable bearing has a 750-pound load limit and is 5/16 inches thick by 9 inches wide. It is zinc-plated for resistance to corrosion and has a load capacity of 750 pounds. This VXB bearing has a 9-inch circle plate and is for use in lazy susan turntables with a diameter between 15 and 30 inches.
Rolling 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 rolling 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.
