How to Read Tecma Drive Codes: Structure, Prefixes, and Suffixes

Why is it important to understand the code of a Tecma Drive slewing ring?

When you need to replace a slewing ring on a crane, an excavator, or industrial equipment, the manufacturer's code is the key to getting the exact part. In the case of Tecma Drive, each designation summarizes key technical information: mounting type, raceway geometry, roller arrangement, and other construction features.

Correctly interpreting that code saves you from costly mistakes: ordering a slewing ring that doesn't fit, can't support the load, or has a different hole pattern. That's why in this guide we show you how to read Tecma Drive codes, with real examples from our slewing ring line.

If you work in maintenance or purchasing, mastering this nomenclature will save you time and give you more confidence when requesting a quote. And if you have doubts, you can always ask us: we are the exclusive representative of Tecma Drive in Argentina.

General structure of a Tecma Drive code

Tecma Drive slewing ring codes typically have an alphanumeric format divided into blocks. For example, let's take the code TD-W9-RA. The first block, TD, identifies the Tecma Drive brand. It is a common prefix for all its products.

The second block, in this case W9, corresponds to the specific series or model of the slewing ring. This part of the code is related to size, load capacity, and internal geometry. Each series has its own characteristics that make it suitable for certain applications.

The third block, such as RA or RL, completes the model designation. To order the exact module, copy it exactly as it appears on the nameplate: there is no need to interpret it.

Common prefixes and suffixes in Tecma Drive slewing rings

The prefix TD is present in all Tecma Drive slewing ring codes we supply. It is the brand abbreviation and does not vary between models. After the prefix, a combination of letters and numbers defines the series.

In TD slewing drives, the letter after the prefix marks the version: TD-E is the standard version and TD-R the IP66-protected version. The number gives the size of the drive. The final blocks, such as RA and RL, complete the designation and are copied as they are when ordering.

It is important not to assume the meaning of a suffix without verifying the model's datasheet. Therefore, if you have a slewing ring with a code that does not appear in our examples, we recommend consulting us with the full code or a photo of the identification plate.

Real examples of Tecma Drive codes

Let's look at three real Tecma Drive slewing drive codes that we handle at MR Accesorios Industriales: TD-W9-RA, TD-R7-RL and TD-E7-RL. In all three, the TD prefix identifies the slewing drive line. TD-E7-RL is the standard version and TD-R7-RL the IP66-protected version.

The RA and RL blocks are part of each model's designation. To get a quote, copy the full code from the nameplate: that is how we identify the exact drive.

If you are replacing a slewing ring and have the old code but cannot find the same one in the current catalog, don't worry: manufacturers sometimes update designations. In that case, we help you identify the equivalent slewing ring based on the main dimensions: outer diameter, inner diameter, total height, and hole pattern.

How to use the code to request a quote for your slewing ring

When you request a quote from us, the most helpful thing is to provide the full code of the slewing ring, as it appears on the plate or in the equipment manual. With that information, we can quickly verify if it's a model we handle and give you an accurate response.

If you don't have the code, you can also send us a photo of the part with a size reference (for example, a ruler next to it). With that, our technical team can identify the model or suggest a compatible alternative.

Remember that we are the exclusive representative of Tecma Drive in Argentina, so we work directly with the manufacturer. That allows us to offer you technical advice and support with every purchase.

Frequently asked questions about Tecma Drive codes

A common question is whether the code includes information about the slewing ring material. In general, the designation does not specify the steel used, but it may indicate whether the slewing ring has anti-corrosion treatment or a special seal. To know those details, it is always best to consult the model's datasheet.

Another frequent question is whether you can order a slewing ring with the same code but with modifications. Tecma Drive offers some customization options, such as special gears or threaded holes. If you need a variant, we advise you on feasibility and the corresponding code.

Finally, many customers ask if Tecma Drive codes are compatible with those of other brands. The answer is no: each manufacturer uses its own nomenclature. However, based on dimensions and load capacity, we can find an equivalent Tecma Drive slewing ring for your application.
