TECMA DRIVE ungeared slewing rings are power transmission components that allow rotational movement between parts of a structure, supporting axial and radial loads and moments. They are used in equipment where a complete section needs to be oriented or rotated, such as platforms, arms or tables. MR Accesorios Industriales sells this line as part of its power transmission offering, with technical support to select the right model for the application.

On TECMA DRIVE slewing rings the first letter gives the gearing: SD means no gearing. The second block of the code is the ball or roller diameter in millimetres: for example, 20 in the light series, 25 or 32 in the heavier series and 14 in the crossed-roller ones. A final B means solid rings. For a quote, send us the full code from the nameplate; if it can't be read, the outer diameter, inner diameter, height and a photo of the gearing are enough to identify it.

These slewing rings are used in industries that require controlled rotational movements and high load capacity. In Argentina, they appear in earthmoving equipment, cranes, aerial work platforms, mills, mixers, agitator tanks and solar panel orientation systems, among others. They are also present in the food, cement, mining and port industries, where the robustness and precision of the rotation are critical to equipment performance.

To select an ungeared slewing ring, consider the axial and radial loads and the tilting moment it must withstand, as well as the available space and the type of mounting. It is essential to verify the alignment of the support surfaces and the internal clearance recommended by the manufacturer. Proper lubrication and sealing against contaminants extend service life. In applications with oscillating movements or slow rotation, the choice of lubricant and the relubrication frequency are key to avoiding premature wear.

Ungeared slewing rings can be found in different brands on the market, and interchangeability depends on the mounting dimensions, load capacity and raceway geometry. It is not enough for the outer diameter to match: tolerances, the number and size of the rolling elements, and the type of sealing must be compared. Therefore, when looking for an equivalent, it is essential to have the technical data sheet of the original equipment or the exact measurements of the part to be replaced.
