Gortite® Sewn bellows are manufactured from heavy-duty elastomer-coated fabric stitched with nylon or specialty thread. A liquid coating can be added to seams to extend life in severe applications by reducing the thread exposure to the environment or to limit moisture leakage. Available in any size or shape (round, oval, box, way cover, etc.) without tooling charges.
Sewn bellows help keep abrasive grit, impinging chips, and coolant off of machine ways and ball screws. Sewn bellows boots are ideal for protecting hydraulic cylinder rods, shafts and splines. Using a bellows cover is essential for mitigating damage to actuators and motion components, thus maintaining uptime.
