The RINGSPANN SLE series torque limiter is a safety component for power transmissions. It is installed between the motor and the load to prevent damage when torque exceeds the set value. The SLE series, identified by the code SLE followed by a number, is used in applications requiring overload protection without permanent disconnection. MR Accesorios Industriales carries this series as exclusive representative in Argentina.

The SLE series designation is read as SLE followed by a number indicating the size of the limiter. For example, SLE 90.3 corresponds to a size 90 with a construction variant .3. The number is not a diameter or a direct measurement, but an internal code identifying torque capacity and mounting dimensions. To select the correct model, it is necessary to know the required setting torque and the dimensions of the shaft and coupling.

These limiters are used in industries such as food processing, chemical, cement and mining, where an overload can damage costly equipment. In Argentina, they are found in conveyors, mixers, mills, pumps and drive systems in general. Their function is to interrupt transmission when torque exceeds a limit, protecting gears, shafts and couplings. They are also used in applications requiring an overload warning without completely stopping the process.

To select an SLE limiter, the nominal torque and trip torque must be defined, which should be greater than the working torque but less than the strength of the weakest components. It is essential to verify alignment between shafts and the type of coupling. Lubrication and sealing depend on the environment: in dusty or humid environments, additional protection is recommended. Installation must follow the manufacturer's instructions to ensure repeatability of the trip torque.

RINGSPANN torque limiters can be interchanged with equivalent products from other brands, but there is no universal equivalence: each manufacturer defines its own dimensions and capacities. To replace an existing limiter, it is necessary to compare the setting torque, mounting dimensions and connection type. In many cases, a model from another brand can be adapted if the critical parameters are respected. It is always advisable to consult a specialist before replacing a safety component.

If you need a RINGSPANN SLE series torque limiter, write to us via WhatsApp with the complete part number or the model you are looking for. At MR Accesorios Industriales we advise you to select the right variant for your application. We can also help you identify the replacement if you already have a limiter installed. Send us the data and we will respond promptly.
