Bellows Mechanical Seals – DIN Standard
Product Overview:
The bellows range is specifically designed to deliver high performance, durability, and reliability for industrial sealing applications. Each seal is assembled in the First4Seals™ UK headquarters, using components produced in Group manufacturing facilities to ensure consistent performance. The bellows design offers full-length protection of the shaft from particulates, a close radial fit to protect the rotary face during installation, and maximized axial movement to maintain sealing even under shaft deflection. The DIN standard 540 range meets DIN 24960 and ISO 3069 requirements, providing modularity and multiple product iterations from stock.
