Oilfield and mining machinery operate under some of the toughest conditions in the world:

Heavy impact loads

Continuous high-temperature operation

Dust, oil contamination, and vibration

Frequent engagement cycles

Standard clutches often fail under these conditions — but Rubflex PTO clutches are built specifically for them.

Industry Knowledge: The Real Challenges for Heavy-Duty Clutches

Torque rating alone does not determine clutch performance. The real key factors are:

Thermal capacity – ability to withstand repeated engagement heat

Heat dissipation – prevents thermal damage

Structural rigidity – resists deformation under shock loads

Rubflex engineers design PTO clutches with a complete system approach.

Rubflex Product Features：

Reinforced friction systems – high wear resistance and thermal stability
Optimized cooling design – reduces heat build-up
Heavy-duty structural components – impact-resistant and durable
Precise pneumatic control – smooth, controlled engagement

The Result：

Reduced downtime

Lower maintenance costs

Longer equipment operating cycles

Rubflex helps customers improve overall equipment reliability in demanding industries.
