Know More about the Slewing Ring Bearings
Know More about the Slewing Ring Bearings. Slewing ring-bearing possesses an immense load-bearing capacity and can be used in various applications, including windmills. Their design may be customized to a great extent and help engineers improve their processes.
Because of the variability of options, there is a wide range of roller and ball bearings available today. One of these is the slewing ring bearings or the ring for slew bearing that has a flexible design and built and can handle the largest of loads. The word slew means rotating without changing place. Apart from having a good capacity towards bearing loads, these rings can also be used for the load combinations, including the radial, axial, and tilting movements.
In most instances, a slewing ring bearing will support a slow oscillating/turning load, but which has a high weight. Examples may include a swing yarder, a conventional crane, or a windmill’s wind-facing platform. The rings also have many other features that make them highly useful to the engineers and provide them the necessary customizations. Some of the customizations are given below.
- Both external and internal gears can be provided to these rings.
- The bolt-hole patterns may have varying locations and sizes.
- Both crossed-roller and ball bearing designs and varieties are available.
- Rings may have the holes for lubrication.
- The ball-bearing designs may include single as well as the two-row ball bearing designs.
- Clearances may have the variations.
- Options for preloading are available.
There are other kinds of customizations available with the bearings as well. Engineers may consult the manufacturers to get to know more about the options they have.
Applications of the Customizable Slewing Ring Bearings
Slewing ring bearings are used in a variety of situations and industries. Some of their common uses are in areas including:
- Wind power
- Off-highway equipment
- Satellite equipment
- Mining and drilling operations
The Applicable Standards
According to ASME or the American Society of Mechanical Engineers guidelines, the ASME “SRB 1” standard applies to slew-bearing design, application, and maintenance. In practical cases of use and manufacturing, the commonly occurring slewing ring bearings have a thin section and may be made to have a diameter of a meter or more. In most instances, they may have two rows consisting of the rolling elements.
As you might be aware, the rolling elements of bearings slide on the races. In a typical slewing bearing, there are three elements of a race. The “halves” forming the two outer rings and the inner ring will clamp together with one another axially. The outer or the inner race of a slewing ring bearing will have the gear teeth as an in-built and integral feature. The platform is driven effortlessly through the design and resultant function.
Slewing ring bearings are now used in a variety of industries, including construction. Their load-bearing capacity and the transmission of power to the various directions make them useful in a diverse range of situations. You can procure the slewing ring bearings at a more affordable cost when you deal with a leading company and a reputed manufacturer or supplier of the ball and roller bearings. The best of firms will also provide you free-of-cost consultations and take care of your process needs exactly.
