IP65 Clutch

Jonathan Bullick | July 29th, 2015

KEB’s Power-On Clutch series is a great fit for many different applications. Due to it being power-on, it is the safest option for many clutch applications. It is backlash-free, can withstand high operating speeds, can be shaft or flange mounted, and comes equipped with ISO Class B (130°C) insulation.


However, our standard Power-On (Combinorm) clutch is only rated at IP20. Many facilities, production lines, machines, and applications do not have the cleanest environments.


Due to this, we have designed an enclosed IP65 Clutch for applications that demand a higher protection standard. It is often referred to as our Combibox Clutch-Brake Series, but the function is the same as our Combinorm power-on clutch.

Design Features

We designed our enclosed clutch to be able to meet a wide array of application specifications. In regards to mounting the unit, it can easily be configured to mount with conventional motors and gearboxes. It can be either flange or foot mounted with varying size bores and/or shafts on the input and output.


If needed, we can also incorporate a brake inside the unit for those quick start/stop applications. The Combibox torque range is offered from 7-250 Nm and the units support a wide array of operating voltages.


Ingress Protection

From first-hand experience, I know that production floors aren’t always the tidiest. Whether you have production lines manufacturing aluminum ingots or conveyor belts in your system; oil, coolant, lubricant, or water can make its way into the clutch unit and reduce the effective torque, thereby rendering it ineffective or unsafe.

KEB’s IP65 clutch is intended for these types of harsh environments. The unit is considered dust-tight and can withstand powerful water jets from either the application or during routine cleaning. On top of normal IP65 protection, we can take extra precautions by adding sealing washers, gamma rings, and even Loctite any component fittings making the unit oil-tight. Our IP65 clutch that is oil-tight is our highest protected clutch and will be able to withstand your harsh production environment.
