The RINGSPANN SRE series torque limiter is a safety component for power transmissions. It is installed between the motor and the machine to disconnect movement when torque exceeds the set value, preventing damage to gears, shafts and couplings. MR Accesorios Industriales supplies this line as exclusive representative in Argentina and advises you to choose the model according to your application.

The SRE series designation is read by its base code and the numeric suffix indicating size. For example, SRE 90.3 corresponds to a size 90 with variant 3. That number is not a diameter or a load: it identifies the housing capacity and adjustment range. To select the correct limiter, you must start from the nominal torque of the transmission and the desired trip torque, not just the size.

These limiters are used in industries where an overload can break equipment: food processing, cement, mining, chemical, aggregate processing and process plants. In Argentina they are commonly seen in conveyor belts, bucket elevators, mixers, mills and packaging machines. They protect the entire drivetrain and reduce downtime due to breakage.

To choose the model, define the working torque, the coupling type (direct or via pulley), the rotation speed and the environment. Sealing and lubrication are key: a poorly lubricated limiter can trip earlier than expected. Respect shaft alignment and the mounting indicated by the manufacturer. If the equipment operates with reversing rotation or high temperatures, mention it when requesting a quote.

Torque limiters are interchanged between brands by torque range and mounting dimensions, but there is no universal equivalence: each manufacturer uses its own nomenclature. To replace an existing unit, the safest approach is to compare the set torque, shaft diameter and mounting interface. With that data, a functional replacement can be found within the same series or another brand.

If you already have the code SRE 90.3 or your machine model, send it via WhatsApp to MR Accesorios Industriales. We will provide a quote and confirm availability. We can also help you interpret the designation if the limiter is mounted and you cannot see the nameplate. Write to us with the data you have and we will respond promptly.
