Why Choose Exact Slewing Ring Bearings?
Slewing ring bearings describe an angular bearing with two concentric rings, which involve balls or rollers for easy movement in load transmission and power applications. You can construct the two rings with toothed gears for increased torque, enabling movements in any direction from the center of the bearing. They are perfect both for low-speed and heavy-load applications, such as construction and excavation machines and for more intricate and precise ones, like medical tools and devices. Considering all the above, it becomes clear that there are many advantages to using slewing rings and bearings.
Key Benefits and Differences in Slewing Ring Bearings
- Slewing ring bearings have some special advantages over other ball and roller bearings, mainly in very heavy load applications with large requirements of freedom of movement.
- Slewing ring bearings provide 360-degree joint support to complex load-bearing systems and enable contemporary multidirectional movement.
- Shaftless Design: Slewing rings are designed shaft- or spindle-less, enhancing the bearing motion and providing room for other operational components.
- Load Carrying Capacity: Slewing ring bearings are designed to deal with the motion of heavy loads most efficiently.
- Ideal Stiffness: Slewing ring bearing designs accommodate a large sweep of motion. The material stiffness is so high that they are suitable for applications where the bearing needs to be stiff or rigid.
- Low Friction: The most special properties for which slewing bearings are valued are their low friction and freedom of movement. This enhances process efficiency while elongating the service life of the bearing and surrounding equipment.
- Longer Operating Life: The slewing ring bearing is highly resistant and features low friction load carrying. It reduces the pressure and friction between the bearing and corresponding components, thus decreasing the wear at the equipment level. This bears intrinsic service life and, consequently, the overall system.
Applications of Slewing Ring Bearings
- Slewing ring bearings are quite suitable for a large variety of industries and applications, given their versatility and effectiveness. They find many applications in military and defence equipment, manufacturing, and transportation. Some of the common uses are:
- Construction: Slewing rings find applications in the construction industry for load-carrying and lifting equipment such as elevators, cranes, hydraulic excavators, and borers.
- Mining: Slewing rings find application in mining excavation and tunnel boring, whereby such equipment can move around freely under heavy loads.
- Transportation: Trains, trams, and subways often employ slewing rings to achieve free, easy movement of vehicles.
- Tooling and Machining: These slewing ring bearings are normally used to effect self-contained movement in the correct machine tools. They provide for free multi-axis movement of machine tool spindles in milling and turning applications.
Bearing Maintenance and Care
Although slewing ring bearings can provide very low maintenance compared with other bearing designs, they can frequently suffer damage and failure due to too little or improper lubrication. When mounting bearings, be sure you are greasing your rings with solid lube during the pre-mount phase of your process. Schedule post-mount lubrication and maintenance on a regular basis to ensure the service life of your bearings. Apart from making sure that the lubricant is always in good condition, periodic checks for dirt, dust, and other contaminants in the lubricant will have to be done since these can potentially abrade or wear down your bearings, reducing the service life and increasing repair and replacement costs. Unless your slewing ring bearing is mounted on a level surface or one that is easily deformed, the weight of your loads will press unevenly on your bearing. This can result in localized wear, which again will upset the bearing’s life even more. Try to ensure your bearings run on a flat, solid surface to prevent unnecessary wear.
