Air passages in the sealing case let the dust cover breathe while blocking dust suction, reducing contamination in rotary compression molding.
A flexible bellows with wave-shaped corrugations seals the braking device, accommodating greater brake pad mobility in parallel directions.
A flexible membrane joint system with axial support ribs eliminates rotary seals to resolve reliability and complexity trade-offs in atmospheric diving suits.
A bellows device incorporates a flexible compensating section that absorbs radial movement, reducing material wear and seam stress on the bellows folds.
