The RINGSPANN metal bellows coupling is a power transmission element that joins two shafts and absorbs misalignments with no appreciable angular backlash. The steel bellows, instead of an elastomer, gives it torsional rigidity and makes it suitable for repeatable positioning movements. It is used in servomotors, encoders, spindles and mechanisms where coupling backlash would ruin precision. MR Accesorios Industriales supplies it in Buenos Aires, Argentina, with more than 80 years in the industrial sector.

The designation is read in two parts: first the series, WK1 or WK2, and then the size. The number that follows the letters indicates the construction family, and the size defines the capacity of each body: in the catalog they appear from WK1 / size 5 and WK1 / size 10 up to WK1 / size 45 and WK1 / size 100, while the WK2 series starts at WK2 / size 1 and WK2 / size 5. To request a quote, provide the complete part number exactly as it appears on the drawing or on the equipment nameplate.

These couplings are seen in Argentine industry on servomotor beds, ball screws of machine tools, encoder shafts, dosing and packaging, and in automation equipment where repeatability is needed. They also appear in precision pumps and in laboratory or metrology drives. Since they have no elastomer, they tolerate temperature better and do not suffer the typical aging of a rubber spider, although they require more careful alignment.

To choose well, first look at the nominal torque and the peak that the drive will withstand, then the admissible shaft diameter at each hub and finally the misalignment the bellows allows: angular, radial and axial. During assembly, align the shafts before tightening the fastening screws, verify the available axial clearance and avoid forcing the bellows to compensate for a bedplate error. Lubrication does not apply to the bellows, but it is advisable to keep the area clean and check the tightening of the set screws.

Among brands, metal bellows couplings are interchanged by performance: shaft diameter, torque, torsional rigidity and admissible misalignment. There is no universal equivalence table, so replacement is resolved by comparing those variables and the mounting dimensions.
