Key Features and Benefits
  • 1. Shock Absorption and Vibration Isolation The flexible rubber bellows work with compressed air to absorb shocks and reduce vibration transmitted through compatible equipment, supporting smoother operation and helping protect surrounding components from excessive vibration.
  • 2. Durable Rubber Construction The rubber bellows are designed for repeated compression and expansion under suitable operating conditions. Metal end plates provide structural support and secure mounting when installed correctly.
  • 3. Built-In Bumper Protection The integrated bumper offers additional protection against excessive compression in applications for which the air spring is properly selected, helping reduce the risk of damage when the unit approaches its compressed position.
  • 4. Defined Mounting Configuration The GUOMAT 1B6920 features a 3/4" NPT air fitting and specified top and bottom mounting holes. Verifying these details before purchase helps reduce installation mismatches and unnecessary downtime.
  • 5. Replacement Reference Support GUOMAT supports replacement inquiries using original part numbers, cross-reference numbers, product dimensions, and application information to help customers identify a suitable air spring.
