How to check turntable bearing

A turntable bearing is a mechanical component used in turntables, which are devices used to rotate objects. It is also known as a lazy Susan bearing or a swivel plate bearing. Turntable bearings consist of two rings, an outer ring and an inner ring, which are separated by a series of ball bearings or rollers. The inner ring is fixed to the rotating part of the turntable, while the outer ring is fixed to the stationary part. The ball bearings or rollers allow for smooth rotation of the turntable.

Turntable bearings are commonly used in a variety of applications, including:

Industrial machinery: Turntable bearings are used in heavy machinery such as cranes, excavators, and construction equipment.

Aerospace: Turntable bearings are used in the aerospace industry for applications such as satellite tracking and antenna positioning.

Automotive: Turntable bearings are used in car suspension systems to allow for smooth rotation of the wheels.

Home appliances: Turntable bearings are used in microwave ovens, lazy Susan cabinets, and other home appliances.

So how do we check the turntable bearings to prevent failures? In response to this problem, the relevant staff of the turntable bearing manufacturers gave us a detailed introduction.

Checking a turntable bearing involves a few steps

Remove the platter: Start by removing the platter from your turntable. Depending on your model, you may need to unscrew it or simply lift it off.

Inspect the bearing: Once the platter is removed, you should see the bearing assembly. Check for any signs of wear or damage, such as cracks, dents, or scratches.

Check for play: With the platter removed, gently move the tonearm back and forth. If you notice any play or wobble in the bearing, this could be a sign of wear or damage.

Spin the bearing: Spin the bearing with your finger to check for any roughness or resistance. A smooth, free-spinning bearing is a good sign.

Listen for noise: While spinning the bearing, listen for any unusual noises. If you hear grinding or scraping sounds, this could indicate a problem with the bearing.

Reassemble and test: Once you've inspected the bearing, reassemble the turntable and test it out. Listen for any unusual sounds or performance issues that may have been caused by a faulty bearing.

If you suspect that your turntable bearing is damaged or worn, it's best to have it serviced or replaced by a professional technician.
