TECMA DRIVE slewing rings with external teeth are rotary motion components that merge bearing, gear and structural functions into one unit, enabling controlled rotation between two structures. They are specified where heavy loads must be turned accurately while combined forces are supported, as in cranes, aerial work platforms, excavators and handling equipment. MR Industrial Accessories supplies these rings to customers across the United States and in several Latin American countries.

The TECMA DRIVE part number tells you the main features. The first letter indicates the gearing: E stands for external gearing. The next figure is the ball or roller diameter in millimeters — 20 for the light series, 25 or 32 for heavier series, and 14 for crossed-roller versions. A trailing B denotes solid rings. To request a quote, copy the complete code from the nameplate. If the plate is unreadable, provide the outer diameter, inner diameter, height and a photo of the gearing so we can identify the correct variant.

These slewing rings are used in tower and mobile cranes, aerial work platforms, excavators, earthmoving machines, mills, mixers and slewing systems for food and cement plants. They also appear in wind energy assemblies and port structures. Each application determines the sealing, lubrication and surface treatment required, particularly in dusty, humid or frequently washed environments.

When selecting a slewing ring, consider the axial and radial loads, the tilting moment the assembly must withstand, and the torque transmitted by the sprocket. Proper installation calls for flat, machined support surfaces, fasteners tightened to the specified torque, and careful alignment between the ring and the sprocket. Sealing and regular lubrication are critical for service life, especially on outdoor equipment.

Slewing rings can be interchanged between manufacturers based on code, mounting dimensions and number of teeth, not brand alone. Before replacing a unit, verify the reference diameter, module and tooth type, and compare the overall height and mounting holes. A functional equivalent may be found within the same series or from another brand with matching critical dimensions.
