Our attractive 1″ diamond-cut beveled edge, tempered 1/2” thick patio glass lazy susan, revolves to give everyone at the table easy access to wine glasses, condiments, and full-course meals at the same time. Each glass lazy susan has a 2 1/2”- 3” hole to spin effortlessly around your umbrella pole, each glass top we produce is a unique, high décor, beveled, tempered glass server that will add a beautiful, decorative touch to your patio table. Our turntable can support weights from 300 to 650 pounds (depending on the diameter size of the glass Susan), and still spin effortlessly. Silicon inserts maintain the separation between each ball bearing to reduce rotational friction and also support heavy radial and axial loads, so the individual ball bearings do not contact each other but rotate within a refined individual bearing channel. Our turntable ball bearings are captured within a precision, refined, beautiful spun aluminum casing, and the ball bearings and casing will never wear out or rust. The spun aluminum bearing casing is not permanently attached to our patio glass lazy susan, the bearing casing has several anti-skid silicone pads inserted into the top as well as the bottom of the bearing unit, so the bottom of the bearing will rest on the hard surface of your patio table without sliding and the glass will rest on top of the bearing and will not slide, making it much easier to lift the glass Susan straight up your umbrella pole to clean the table and to clean and polish both sides of the tempered glass lazy susan aa well as avoiding taking the umbrella down, getting water, etc., into the bearing turntable mechanism. The turntable bearing mechanism diameter size is expertly matched to the diameter of your patio glass lazy susan diameter size. When we ship, we expertly pack the glass to avoid any damage to either one by UPS or FedEx. Shipment is generally within a week to 10 days from the date of order. Silicone oil lubrication must be applied to each ball bearing before first use for an ultra-smooth rotation. Oil is available at any hardware store.
