Stainless steel shaft couplings are used in the food, pharmaceutical, and medical technology industries because they are corrosion-resistant, easy to clean, and hygienic. The smooth, rust-free surface prevents dirt and germ accumulation and meets high hygiene standards.

JAKOB Drive Technology GmbH now offers various stainless steel couplings as standard series: the metal bellows couplings KG-VA, KGH-VA, and MKG-VA, the spacer coupling series WD-VA and WDB, the elastomer coupling EKM-VA, as well as safety couplings SKVA-N and SKVA-K along with variants.

Especially noteworthy is that both the metal bellows coupling KGH-VA and the WDB series are manufactured in a very assembly-friendly half-shell design. This construction allows for easy assembly and disassembly, even in tight spaces. The fixed hub halves are simply placed onto the shaft and screwed to the loose half-shell pieces. This particularly saves time with stationary shaft pins, as the elaborate disassembly of the drive and/or driven unit is eliminated. Thanks to their rust-free stainless steel construction, these couplings are also ideal for use in the food industry.

Various series for different application areas

The KG-VA series can be used at temperatures up to 350 °C and is designed for shaft diameters from 10 to 90 mm and torque values from 30 to 1000 Nm. The KGH-VA series is wear- and maintenance-free, also operable up to 350 °C, and covers shaft diameters from 7 to 85 mm and torque values from 10 to 1200 Nm. It is available in variable lengths with 2- or 4-well bellows.

The MKG-VA is a miniature metal bellows coupling with a clamping hub, available with 2- or 4-well bellows, capable of transmitting up to 15 Nm and operable up to 350 °C.

New in the range is the elastomer coupling EKM-VA, which can transmit torques up to 500 Nm and is usable at temperatures up to 90 °C. It features an assembly-friendly clamping hub.

The spacer coupling WD-VA is available in variable lengths up to 3 meters and ensures backlash-free torque transmission. It is also operable up to 350 °C and suitable for shaft diameters from 7 to 85 mm with torques from 10 to 1200 Nm.

The safety couplings of series SKVA-N and SKVA-K are designed for indirect drives, while series SKVA-EK and SKVA-KG are for direct drives. They are suitable for use in the food industry or medical technology, which require particularly high hygienic standards. The series without elastomer are also especially heat-resistant and can be used in oven or cold systems.
