The three-lobed bellows design increases usable working height while maintaining structural stability. This allows smooth vertical displacement under dynamic loads.
Designed to maintain consistent support force across varying pressure levels, ensuring balanced machine operation.
The reinforced rubber construction provides excellent resistance to repeated compression cycles, temperature variation, and industrial environmental stress.
High-strength end plates ensure secure installation and long-term structural integrity.
