What is a Tecma Drive slewing ring
A Tecma Drive slewing ring is a large-diameter bearing designed to support axial, radial loads and tilting moments simultaneously. Unlike conventional bearings, its raceway is integrated into a large ring, allowing rotational movement to be transmitted between two structures.
These components are used in equipment where one part must rotate relative to another, such as cranes, excavators, rotary tables, solar trackers, and aerial platforms. Their compact design simplifies assembly and reduces the number of required parts.
Tecma Drive offers a line of slewing rings with different gear and raceway configurations, adapted to various load and precision requirements. At MR we market these slewing rings as the exclusive representative of the brand in Argentina.
Technical features of slewing rings
Tecma Drive slewing rings are manufactured with high-strength steels and heat treatments that ensure durability and load capacity. Depending on the model, they may include external or internal gearing or no gearing, and ball or cylindrical roller raceways.
The choice of raceway type depends on the application: ball types are suitable for moderate loads and high speeds, while roller types withstand higher loads and tilting moments. They can also be supplied with seals and grease fittings for easier maintenance.
Each slewing ring is identified by a code indicating its series and features. For example, codes beginning with TD-W9, TD-R7, or TD-E7 correspond to specific series within the Tecma Drive line.
Typical applications in Argentine industry
In Argentina, Tecma Drive slewing rings are used in road machinery, loading cranes, drilling equipment, antenna orientation systems, and the mining industry. They are also common in rotary work tables and welding positioners.
Their ability to support combined loads makes them ideal for equipment working under demanding conditions, such as earthmoving or heavy load handling. Preventive maintenance and proper lubrication are key to extending their service life.
If you are replacing an existing slewing ring, it is important to verify dimensions, gear type, and mounting hole arrangement. With that data, we help you identify the equivalent Tecma Drive model.
How to identify a slewing ring by code
Tecma Drive slewing ring codes follow a structure indicating the series and raceway type. For example, the prefix TD-W9 identifies a series with ball raceway and external gearing, while TD-R7 and TD-E7 correspond to other configurations.
To get a quote, you can send us the full product code, such as TD-W9-RA, TD-R7-RL, or TD-E7-RL, or the measurements and features of the slewing ring you need. With that information, we indicate the available option and its equivalent alternative.
We work with Tecma Drive slewing rings, which includes 186 references. If you cannot find the exact code, don't worry: with a photo of the part and its dimensions, we can help you identify it.

Maintenance and service life
Maintenance of a slewing ring includes periodic lubrication, checking axial and radial clearance, and verifying the condition of seals. Tecma Drive recommends greasing intervals based on frequency of use and working environment.
A common symptom of wear is increased clearance or noise during rotation. If these signs appear, it is advisable to inspect the slewing ring and evaluate its replacement to avoid major equipment failures.
At MR we guide you on maintenance practices and provide quotes for the necessary spare parts to keep your machinery operational.
