In many cases, it's not the gasket's fault.
At ttv, we see time and again in damage analyses:
The actual cause is the lubrication concept.
Not all greases are created equal.
Critical influencing factors:
▪ Additive packages that chemically attack elastomers
▪ Incorrect viscosity → increased temperature → material aging
▪ Over-lubrication instead of a defined amount of lubricant
▪ A grease approved for the bearing—but not for the seal
The result:
Premature wear, leakage, unplanned downtime.
Our approach at ttv:
We view drive seals systemically—not in isolation.
✔ Check material and media compatibility
✔ Coordination with bearing manufacturers & lubricant suppliers
✔ Optimization of lubricant type and quantity
✔ Technical consulting instead of relying on catalog specifications
Less grease—but the right kind—often significantly increases service life.
Service life is achieved through coordination. Not by chance.
