How to identify and quote a ThyssenKrupp / Rothe Erde slewing ring

ThyssenKrupp / Rothe Erde slewing rings are large-diameter bearings designed to support axial, radial loads and tilting moments simultaneously. They differ from a conventional bearing by their size and by the ability to transmit rotational movement between two structures. In Argentine industry they are also known as slewing bearings, and are used when equipment needs to rotate on a vertical or horizontal axis with heavy load.

Each slewing ring combines a geared ring, raceways and rolling elements that can be balls or rollers. The geared ring allows coupling a drive pinion, whether hydraulic or electric, to generate controlled rotation. The internal geometry is designed to distribute loads uniformly and avoid stress concentrations that shorten the service life of the component.

At MR we market ThyssenKrupp / Rothe Erde slewing rings for replacement and for new projects. If you have the code engraved on the part, such as 060.20.0644.500.01.1503, you can send it to us and we will quote the exact replacement. We also work with identification by dimensions when the code is not legible or the slewing ring is very deteriorated.

ThyssenKrupp / Rothe Erde slewing rings appear in equipment where rotation is part of the work cycle. In mobile cranes and tower cranes, the slewing ring joins the rotating part with the chassis and supports the weight of the boom and the load. In excavators, it allows the rotation of the superstructure on the undercarriage, with highly variable loads depending on the position of the arm.

They are also used in wind turbines to orient the nacelle according to wind direction and to adjust the blade angle. In the port industry, gantry cranes and loading booms depend on slewing rings for precise movements with heavy containers. Other equipment that incorporates them are aerial work platforms, welding positioners and rotary tables of machine tools.

If you are repairing equipment and need to replace the slewing ring, it is advisable to gather as much data as possible. The complete code, such as 060.20.1094.500.01.1503, is the most direct reference for quoting. If it is not visible, you can take measurements of outer diameter, inner diameter, total height and gearing module, and with that we help you identify the correct option.

ThyssenKrupp / Rothe Erde slewing rings have an alphanumeric code engraved that identifies the series, size and configuration. That code is usually on the outer ring or on the inner ring, sometimes on a riveted plate or directly machined into the steel. An example of that format is 061.20.0544.500.01.1503.

In addition to the code, it is useful to record the main dimensions: outer diameter, inner diameter, total height, number and type of teeth, and whether the gearing is external or internal. It is also advisable to note the mounting direction and the position of the fixing holes, because there are configurations that look the same but differ in the hole distribution or in the type of sealing.

When you send us a photo of the identification plate or the engraving, together with the dimensions, we can identify the model. If the code is complete, such as 060.20.0644.500.01.1503, the quote is direct. If you only have dimensions, we tell you what additional data we need to avoid getting the model wrong.

ThyssenKrupp / Rothe Erde manufactures slewing rings in several series depending on the type of rolling element, which can be balls or rollers. The series and configuration are defined by the complete code of the part, so it is advisable not to replace a slewing ring just because it looks similar.

Within each series there are variants with external gearing, internal gearing or without gearing. In slewing rings with external gearing, the drive pinion is mounted on the outside. Those with internal gearing are used when space is limited or when the drive must remain protected inside the structure.

At MR we distribute ThyssenKrupp / Rothe Erde slewing rings. If you have the code of the original part, such as 060.20.1094.500.01.1503, we quote that same model. If you are assembling new equipment, send us the loads, the tilting moment and the work cycle, and we will quote the corresponding slewing ring.

To quote a ThyssenKrupp / Rothe Erde slewing ring, the most practical thing is to send us the complete code that appears on the part. That code, such as 061.20.0544.500.01.1503, defines the exact model and avoids confusion. If you do not have the code, we need the main dimensions: outer diameter, inner diameter, total height, module and number of teeth, and type of gearing.

It is also important to know the application and the equipment where the slewing ring is mounted. A slewing ring for a tower crane is not the same as one for an excavator, even if the dimensions are similar. With the application data we avoid confusing models with similar dimensions.

When you send us a photo of the current slewing ring, with the code visible or with a ruler next to it for scale reference, we speed up identification. With that data we quote the ThyssenKrupp / Rothe Erde slewing ring as soon as possible.

One of the most frequent mistakes is ordering the slewing ring only by outer diameter, without verifying the complete code. Two slewing rings with the same diameter can have a different gearing module, different height or different hole distribution. That is why it is always advisable to record the engraved code, such as 060.20.0644.500.01.1503, before placing the order.

Another common mistake is not checking the condition of the fixing holes and bolts. If the holes are ovalized or the bolts are loose, the slewing ring works poorly and wears prematurely. Before mounting a new slewing ring, you must verify that the support surfaces are flat and clean, and that the bolts have the correct torque.

It is also advisable to pay attention to sealing and lubrication. ThyssenKrupp / Rothe Erde slewing rings usually have seals that protect the raceways from water and contaminants. If the seal is damaged, the grease becomes contaminated and the slewing ring fails early. When mounting, the type of grease and the amount indicated by the manufacturer must be respected.

At MR we work with ThyssenKrupp / Rothe Erde slewing rings for industrial and load-handling equipment. If you need to replace an existing slewing ring, the most direct way is to send us the complete code, such as 060.20.1094.500.01.1503, by WhatsApp or email. With that data we quote the exact model.

If you do not have the code, you can send us the main dimensions and a photo of the part. With that we identify the slewing ring and send you the quote. If the application requires a special configuration, tell us the equipment and the loads and we will quote it.

To quote your ThyssenKrupp / Rothe Erde slewing ring, write to us by WhatsApp or email with the code, the dimensions or a photo of the part. We will reply as soon as possible with the proposal and the technical data of the selected model.
