Turntable Bearings and their Uses
There are many uses for turntable bearings, which might also be known as Lazy Susan bearings or trailer rings, depending on the application. They can be employed in a variety of industries, though commonly they are used in farm machinery as trailer rings. They have a large diameter so that trailer steering axles can oscillate.
Turntable bearings come in a variety of sizes depending on their intended usage, so all of this will inform the bearing that is purchased. It will also need to be of a suitable quality – purchased from a well known, reputable bearing supplier as either a direct replacement part, or a premium quality alternative. There are many bearing suppliers selling a range of quality turntable bearings online, so selecting the correct dimensions, fit and axial load is very important.
Turntable bearings are most often used for shelving and storage, revolving displays, garage racks, and various items of machinery. Trailer rings are used in applications such as agricultural trailers, irrigation systems and farm machinery. They can also be used in light duty industrial applications; various types of material handling equipment and welding equipment can benefit from turntable bearings. They are lower cost than slewing rings, making them a popular alternative.
They are highly versatile, and turntable bearings with different specifications are available to suit all of these purposes. Due to their rotating mechanism, turntable bearings can become worn out over time. If this is happening, there may be visual signs of wear and tear, and there might be a change in operation too; there may be wobbling or looseness, where the bearing is no longer performing its rotating function correctly. There might also be sticking and tightness if the bearing is causing friction. Turntable bearings should be examined regularly to make sure they are working correctly, which is important for safety, especially when the bearings are being used in heavy machinery or as trailer rings.
How to Measure Bearings to Buy the Right Size
When replacing bearings, it’s important to buy an equivalent size which means measuring the bearing you have already got. Here’s a brief guide to measuring turntable bearings:
- Using vernier calipers, measure the outside of the bearing first. The larger legs will be used here, so they are positioned in the centre of the outside diameter.
- Then measure the inside diameter. Use the small legs this time on the inside of the bearing.
- Finally measure the width. Using the larger legs, make sure they are flat on either side of the bearing.
Make sure to record the dimensions at each step so you can find the correct bearing size when buying replacements. It is also important to make sure the bearing replacement has the correct axial load for the intended purpose. This will ensure you have the correct information needed to purchase the right turntable bearing replacement online. If you’re ever unsure, enquire with the supplier. They will be able to give you up to date information and can inform you further on their range of bearings, and their uses.
