COLOSSUS C65 High Temperature Rotating Welded Metal Bellows Seal

Rotating welded metal bellows seal for high temperature service. Its dynamic performance and adaptability come from welded bellows technology: a 45 degree wave profile lowers stress peaks and spreads the stress at the inner weld to prevent early failure, keeping the seal faces in contact. Flexible graphite is used only as a static seal. Connection dimensions comply with DIN 24960 and GB 6556.

Key features

• Standardized design to DIN 24960 and GB 6556
• Welded metal bellows: good dynamic performance, wide adaptability
• Flexible graphite static seal, simple and reliable
• Set screw positioning
• Corrosion-resistant design
