TECMA DRIVE slewing rings with internal gearing are rotary motion components that support and turn large structures. The gearing is integrated into the bearing, so a drive pinion meshes with the internal teeth to rotate the assembly around its axis. They are used where loads need to be positioned or oriented with control and repeatability.

The TECMA DRIVE code identifies the main features of each slewing ring. The first letter indicates the gearing type: I stands for internal gearing. The next block gives the ball or roller diameter in millimeters. For instance, 20 corresponds to the light series, 25 and 32 to heavier series, and 14 to crossed-roller versions. Codes that end in D followed by a number are special designs, such as double-row ball types. To request a quote, provide the complete code from the nameplate. If the nameplate is unreadable, the outer diameter, inner diameter, height, and a photo of the gearing are usually enough to identify the part.

These slewing rings are found in medium and large rotary equipment: cranes and booms, aerial work platforms, rotary machining tables, material handling systems, welding positioners, and orientation units in industrial plants. They are common in metalworking, heavy industry, mining, port logistics, and special machinery manufacturing. Because the teeth are cut on the inner face, the drive pinion sits inside the ring diameter, which suits compact assemblies and helps protect the gearing.

When selecting a slewing ring, check the mounting diameter, the number of teeth and gear module, the fastening type, and how it interfaces with the slewing bearing. During assembly, alignment between ring and pinion is critical: errors in concentricity or height lead to uneven wear and noise. Use the gear lubrication specified for the load and rotation speed, and verify backlash between teeth and bolt tightening according to the equipment manufacturer's instructions.

Slewing rings can be interchanged between brands when the mounting dimensions, module, number of teeth, gearing type, and fastening hole locations match. A similar part number is not sufficient; compare drawing against drawing. If you have the original part number or the assembly measurements, send them via WhatsApp or email to MR Industrial Accessories.
