Description
GAM SKG-9 Indirect Drive Safety Coupling 90mm Gear 18mm Bore 3.05-7Nm
The GAM SKG-9 is an indirect drive safety coupling designed to protect machinery from torque overload in automated and motion-control drive systems. It consists of a toothed aluminum gear wheel and a steel hub assembly that transmit torque through indirect engagement while disengaging or slipping when torque exceeds the set threshold. The adjustable torque range of 3.05 to 7 Nm allows tuning to specific application requirements.

Applications
Safety couplings of this type are used in packaging machinery, conveyor drives, printing equipment, robotic joints, and other automated systems where mechanical overload protection is required. When driven torque exceeds the preset threshold, the coupling disengages or slips to protect downstream gearboxes, motors, and driven components from damage. The indirect drive design — where the gear transmits motion without rigid shaft-to-shaft connection — is common in applications requiring compliance or shock absorption between the driver and load. GAM (formerly known as GAM Enterprises) manufactures precision motion control components widely used in European and North American industrial automation. The SKG series specifically targets light-to-medium duty applications where a compact, adjustable torque limiter is needed in a gear-integrated form factor.
This GAM SKG-9 indirect drive safety coupling has been inspected and is in good used condition. The aluminum gear body and teeth show general surface wear and light grime consistent with prior industrial use, as visible in the photos. The bore hub and steel inner race are intact with no visible cracks or damage. Fastener hardware is present. Overall the coupling is structurally sound and complete.
