RINGSPANN SA series torque limiters are safety components for power transmissions. They are installed between the motor and the load to interrupt the transmission when torque exceeds a set value, preventing damage to gears, shafts, chains and other elements. Their synchronized ratchet design allows automatic and precise re-engagement. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, with technical advice to select the right model.
The SA series designation is read by the number that follows it: SA 4, SA 7, SA 11, SA 14, SA 18 and SA 22. That number identifies the limiter's construction size and is related to the torque capacity it can transmit and to the mounting dimensions. The higher the number, the larger the size and the wider the adjustment range. To choose the correct model, consider the nominal torque of the transmission, the desired trip torque and the dimensions of the shaft and coupling. At MR we help you interpret the code and define the variant.
These limiters are used in industries where an overload can cause costly downtime: food processing, cement, mining, steel, material handling, machine tools and process equipment. In Argentina they are found in conveyors, elevators, mills, mixers, pumps and drive systems in general. Their function is to protect the drive train against jams, sudden starts or blockages, disconnecting the torque and allowing the equipment to recover without major damage.
To select a torque limiter, define the trip torque, which must be greater than the working torque but lower than the strength of the weakest components. Rotation speed, coupling type, shaft diameter and length, and environmental conditions also matter. Installation requires careful alignment between shafts and precise adjustment of the trip torque according to the manufacturer's manual. Proper lubrication and sealing extend service life and maintain trip repeatability.
RINGSPANN SA series limiters can be interchanged with equivalent products from other brands, but equivalence is not automatic: trip torque, mounting dimensions, re-engagement type and service conditions must be compared. In general, it is recommended to replace with a model of equal or higher performance and to verify compatibility with the existing equipment. MR Accesorios Industriales is the exclusive representative of RINGSPANN in Argentina and can advise you on the replacement.
If you need a torque limiter for your application, write to us on WhatsApp with the SA code shown on the nameplate or in the equipment manual. With that data we can identify the correct variant and give you a quote shortly.
