Gummi FK Element Brake and Clutch

The Gummi FK Element use a neoprene rubber, reinforced by cord materials that quickly expands inward when pressurised.
This action causes the friction shoes attached to the inside diameter of the tube to engage to the cylindrical surface of the brake drum.
When de-pressurised, the neoprene rubber will move outwards, causing the friction shoe to dis-engage to the brake drum.
It is designed and built to provide dependable brake or clutch operation, suitable for cyclical, high speed as well as general mechanical power transmission.

Applications: Cement Crusher, Drawworks, Main Main propulsion, Marine Tanker Pump, Can Making Machinery, Commercial Laundry Equipment, Metal Forming Machinery, Rubber processing Machinery, Tire Building Machinery, Oil Field Machinery, Ceramic & Clay Machinery, Pulp & Paper and Steel Industries.


When Pressurised > Engage

When De-pressurised > Dis-engage

Benefits of Gummi FK Element Brake Clutch

Self Adjustment

The element tube aill automatically compensate as the friction shoe wears down, eliminating the necessity of adjustment, without reducing the torque capacity

No Lubrication Required

There is no crucial sliding component, which require lubrication, thus saving maintenance time, as well as money

Any Plane Operation

The construction design and characteristics, combines with the centrifugal force, allows the clutch to operate in any plane.

Single Moving Component

The tube is the only moving component, there is no spring or sliding parts, saving maintenance hours.

Shock-Absorbing Effect

Due to the working principle that the tube transmits torque through its sidewall, and the properties of the neoprene rubber material, it works like a shock absorber.
It absorbs the shock loads, protecting the drive components of the transmission as well as reducing effect of torsional vibration.

Flexible Coupling

The neoprene rubber properties of the tube allows the drive to accommodate minor parallel or angular misalignment.

Repair of FK Element Brake Clutch

As the tube is vulcanised to the rim, the only parts that can be repair will only be the friction shoe assembly.
