Ever wonder how really big machines — like cranes, bulldozers, excavators and even a more recent arrival, the wind turbine — are able to rotate without any physical connection, or to sense the motion of other parts of the machine? It’s a special kind of bearing called a ball bearing slewing ring. These incredible rings are integral as parts to make machines move and turn smoothly.
Ball Bearing Slewing Ring Benefits Ball bearing slewing rings offer a number of benefits, particularly in an industrial setting. One of the best features of these is their load-carrying ability. These rings are designed to bear heavy loads of heavy-duty machinery and equipment such that it is a must-have for industries such as construction and manufacturing industries.

It can also be easier to extend the longevity of ball bearing slewing rings by ensuring they are adequately lubricated. Lubrication is used to minimize friction between the balls and the ring, so everything moves smoothly. This will assist in maintaining your ball bearing slewing rings in good condition though regular attention to this and topping up when necessary.

When choosing a ball bearing slewing ring, think about the size and weight of your equipment. It’s important to select a proper size and design to accommodate the load that will be applied to the ring. If you cannot decide between the ball bearing and the slewing ring, feel free to ask one of the professionals at Fo Bearings about compatibility with your machine.

If it’s necessary to install a ball bearing slewing ring also need to be cautious. Getting the ring in place the right way, and seating it well, will save you trouble later on. If you are not certain how to install a ball bearing slewing ring, it’s better to get the assistance of someone who has this expertise, otherwise there might be costly oversights.
