tambee 16 inch aluminum lazy susan heavy duty metal rotating hardware large turntable bearings ring 400mm silver turntable on dining-table for glass top wood top tambee single-row bearing for supporting radial loads. use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads aluminum for durability and resistance to corrosion supports axial loads.<br> 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. 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. ideal for:cake decorations,tv monitor stand,electronic repair, sculpture base,catering services, food display.<br> material: aluminium<br> <b>package included:</b> 1 x aluminium rotating bearing turntable<br> <br> <b>ps:</b> <br> <b>1.the turntable is a fragile product. it may cause damage or rotation issue in the course of transportation. if you meet these situations, please feel free to contact us and we will solve for you. </b><br> <b>2.if your turntable can not be turned freely, you can try some lubricant and synthetic spray lube on it from the side holes and the gap between outer and inner ring. </b><br> <b>3.the turntable bearings are linked by steel beads, it may sound during rotation. loading some weight on it will effectively reduce the sound. </b>
