Modern, innovative mechanical engineering aims to reduce the external mass and increase the power potential of the components. More and more compact drive elements with maximum power density are required. But also the safety aspect, such as collision protection in case of machine crash, is gaining further importance due to increasing automation and dynamization.


With the type SKB, JAKOB Antriebstechnik has a safety coupling generation for overload limitation or collision protection for indirect drives in its product range, which meets these requirements. The high user benefit of the SKB series consists of the interaction of various details. These include high disengagement torques, a compact design, simple assembly by means of a clamping ring hub, high concentricity and bearing load, and simple adjustment of the disengagement torque.

Very high disengaging torques can be achieved by using high-strength quenched and tempered steel with surface hardening or plasma coating of the functional surfaces. The particularly robust ball cage is of great importance in the case of "disengagement impacts" at high speeds, and the grease-lubricated disengagement mechanism is additionally protected against heavy contamination or washout by a labyrinth seal. Furthermore, the SKB series is equipped with clamping ring hubs, which allow significantly larger bore and shaft diameters compared to conical hubs.


Various combination possibilities

The safety coupling SKB can be extended with metal bellows or elastomer coupling attachments if required. JAKOB offers a wide range of hub designs and compensating elements in various sizes. A sophisticated modular system allows production in cost-effective batch sizes and short delivery times.
