The RINGSPANN SWK-BN safety coupling is a precision component that protects power transmission against overloads. It is installed between shafts and limits the transmitted torque: when the load exceeds the set value, the coupling disengages and prevents damage to the motor, gearbox or machine. It is a compact solution for lines where a failure due to overstress can halt production or break costly components. MR Accesorios Industriales supplies it in Buenos Aires, Argentina, with technical advice to choose the right size.
The SWK-BN designation identifies the RINGSPANN safety coupling family. The code is completed with the size, expressed in decimal numbers, as in the examples SWK-BN / size 1.5 and SWK-BN / size 4.5. That number is not a diameter or a shaft dimension: it is the internal reference that defines torque capacity and mounting dimensions. To select the correct one, the machine's nominal torque must be matched against the manufacturer's table. If you have doubts, send us the full code via WhatsApp and we will verify it.
These couplings are used in industries where power transmission requires overload protection: food processing, packaging, textile, plastics, material handling and automation. In Argentina, they are commonly found in production lines that operate with frequent starts or variable loads, where a jam can generate a torque spike capable of damaging the gearbox. They are also used in test benches and laboratory equipment requiring repeatability. MR Accesorios Industriales offers them for replacement and new projects.
To choose an SWK-BN, first define the working torque and the maximum permissible peak. The size must cover that range with margin, but without excessive oversizing. Check the rotation speed, the type of shaft connection and alignment: misaligned mounting accelerates wear and can trigger the coupling prematurely. Lubrication and sealing depend on the version; follow the manufacturer's instructions. If the application involves dust, humidity or high temperature, ask us about variants with additional protection.
Safety couplings are interchanged between brands by function and torque range, not by code. If the original equipment has an SWK-BN, you can replace it with another of similar characteristics, but verify shaft dimensions, keyway and distance between ends. There is no universal equivalence table: each manufacturer defines its own sizes. To avoid mistakes, send us the data of the original coupling (brand, model and dimensions) and we will help you find the right option within the RINGSPANN line we supply.
If you need a safety coupling for your machine, write to us on WhatsApp with the SWK-BN code and the size shown on the nameplate or drawing. You can also send a photo of the assembly and the shaft dimensions. At MR Accesorios Industriales we respond promptly with technical information and a quote. We work with companies throughout Argentina and ship to plant or workshop according to your needs.

Frequently Asked Questions
- How do I know what size of SWK-BN I need?
- The size is chosen based on the machine's working torque and maximum peak. The shaft diameter alone is not enough. Send us that data via WhatsApp and we will indicate the appropriate RINGSPANN size.
- Can a coupling from another brand be replaced by an SWK-BN?
- Yes, if torque, shaft dimensions and mounting match. There are no automatic equivalences between brands. Send us the dimensions of the original coupling and we will verify it.
- What maintenance does this coupling require?
- It depends on the version and the environment. In general, alignment, wear of the transmission elements and lubrication, if applicable, are checked. Follow the manufacturer's instructions for your application.
