A slewing ring is the power transmission element that lets a structure or platform rotate about a vertical or horizontal axis. It supports combined loads while holding orientation, which is why it appears on cranes, lifting platforms and rotary tables. MR Industrial Accessories supplies TECMA DRIVE slewing rings with external teeth in the configurations covered by each model code.

Reading a TECMA DRIVE code starts with the leading letter, which defines the gearing: E indicates external gearing. The next block gives the ball or roller diameter in millimetres, for instance 20 in the light series, 25 or 32 in the heavier series, and 14 on crossed-roller versions. A code that closes with D plus a number marks a special version, such as the double-row ball type. To request a quote, send the complete code shown on the nameplate. If the nameplate is unreadable, the outer diameter, inner diameter, height and a photo of the gearing are enough for identification.

Typical users are found in metallurgy, construction, mining and material handling. Tower cranes, aerial work platforms, cutting tables and rotation equipment on production lines all rely on these rings. The ring provides controlled turning of heavy parts with smooth transmission, and it works together with sprockets and drive systems.

Selection depends on the axial and radial load to be carried, the tilting moment and the operating environment. The mounting surface must be flat and rigid, and the ring has to be aligned carefully with the sprocket to prevent premature wear. Lubricating the teeth and the internal bearings correctly is what protects service life. In dusty or humid conditions, additional protection is worth considering.

Slewing rings from different manufacturers can sometimes be equivalent, but interchangeability comes down to mounting dimensions, tooth module and load capacity. A similar code is not sufficient; drawings and technical data have to be checked. Our team can help you compare functional characteristics and narrow down the right ring for your application.
