High-Quality Operating Limits for Industrial Applications - China Suppliers & Factory - Pressure ≤3.0MPa, Temperature ≤450℃
Product Introduction
Acts as the elastic element, ensuring superior sealing performance across wide temperature ranges and thermal transients.
The bellows body does not rotate with the shaft, reducing dynamic friction, vibration, and mechanical wear.
Features built-in cooling passages to control seal face temperatures and mitigate wear from thermal expansion.

Frequently Asked Questions
Because the bellows body does not rotate with the shaft, it significantly reduces dynamic friction, vibration, and mechanical wear, leading to higher overall reliability in demanding environments.
It utilizes a precision-manufactured metallic bellows as its elastic element. This design maintains sealing integrity during rapid thermal transients and functions reliably across both extreme heat and low-temperature conditions.
The forced-cooling passages control the temperature around the seal faces. This mitigates the wear caused by thermal expansion and contraction, thereby extending the operational life of the seal.
The seal chamber is rigidly connected to the equipment via flanged joints, which provides a secure installation and minimizes the risk of loosening or leakage during heavy industrial operations.
They are widely used in pumps, agitators, and rotary machinery within petroleum refining, chemical processing, chemical synthesis, and steam systems where high-temperature endurance is required.
