The RINGSPANN WK-H series metal bellows coupling is a precision transmission component that connects two shafts while compensating for misalignment with no angular backlash. Its metal bellows body absorbs vibration and allows high-speed rotation with immediate response, ideal for servomotors, encoders and spindles. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, with technical advice to select the right size for your application.

The WK-H series designation is read by model and size: for example, WK3-H / size 5 or WK4-H / size 30. The number after WK indicates the construction variant, and the suffix H distinguishes this family of bellows couplings. The size, in turn, defines the mounting dimensions and transmission capacity. In the RINGSPANN catalog you will find a wide range of sizes and model combinations. To request a quote, send us the full code shown on your drawing or equipment.

These couplings are used in industries that require precise and repeatable movements: machine tools, automation, robotics, digital printing, medical and laboratory equipment. In Argentina, we find them in packaging, dosing and axis control lines, where backlash-free transmission is critical. They are also used in applications with servomotors and actuators that need to compensate for small alignment errors without losing accuracy. MR Accesorios Industriales sells them throughout the country, with a focus on Buenos Aires, Argentina and the industrial belt.

To select the right coupling, take into account the nominal and maximum torque, the rotation speed, the permissible misalignment (axial, radial and angular) and the shaft diameter. The metal bellows works without lubrication and tolerates moderate temperatures, but it is sensitive to overloads and corrosion if the right material is not chosen. During installation, ensure careful initial alignment and avoid forcing the bellows; use the fastening screws at the recommended torque. If the environment has dust or moisture, ask us about protected variants.

When replacing a coupling, interchangeability between brands depends on the mounting dimensions, shaft diameter and required torque. It is not enough for the size to match: you must check the overall length, outer diameter and type of fastening. The RINGSPANN WK-H series is often compared with other metal bellows lines on the market, but each manufacturer has its own tolerances. If you send us the original code or the shaft dimensions, we help you find the right equivalent within our line.
