RINGSPANN PA series force limiters are safety devices installed in power transmissions to interrupt motion when the load exceeds a set value. They protect shafts, gears, chains and couplings against overloads, jams or sudden starts. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, as exclusive representative of RINGSPANN, with technical advice to choose the right model for each application.

The PA series designation is completed with a number that identifies the limiter size: PA 12, PA 20, PA 30, PA 50 and PA 75. That number is not a diameter or a load, but a size code within the family. To select the correct limiter, consider the setting torque, rotation speed, coupling type and environmental conditions. With the complete code, such as PA 30, you can request a quote and check availability of the exact variant.

These limiters are used in industries where an overload can damage expensive equipment or stop production: food and packaging, material handling, textile machinery, woodworking, cement and metallurgical industries. In Argentina they are common in conveyors, mixers, mills, pumps and chain or belt drive systems. They are also used in lifting equipment and machine tools where fast, repeatable disconnection on a jam is required.

To choose the limiter, define the nominal working torque and the trip torque, which must slightly exceed the former to avoid false tripping. The reset type also matters: manual or automatic, and whether the equipment remains out of service until it is reset. Lubrication and sealing are key to reliable operation; in dusty or humid environments additional protection is recommended. Shaft alignment and mounting on the transmission element must follow the manufacturer's instructions so as not to alter the set torque.

RINGSPANN force limiters can be interchanged with equivalent products from other European brands, but interchangeability is not automatic: you must compare the setting torque, mounting dimensions, shaft diameter and coupling type. In many cases the connecting element must be adapted or the support modified. Therefore, before replacing a limiter, verify the complete designation and service conditions. MR Accesorios Industriales can guide that technical comparison.
