Similarly, virtually all metal connections expand as a system heats up, and then contracts as the system cools. Conventional worm gear, T-bolt, and other clamps are passive, in that expansion or contraction of components cannot be compensated for with out re-tightening or loosening the clamps. This clamping system is an \"active\" clamping mechanism, which monitors and then compensates for the changes by actually changing diameter through a unique worm gear Belleville assembly.\u003c\/p\u003e\n\u003ch4\u003eFeatures:\u003c\/h4\u003e\n\u003cul\u003e\n    \u003cli\u003e\"Active\" clamping mechanism\u003c\/li\u003e\n    \u003cli\u003eUnique worm gear Belleville assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications:\u003c\/h4\u003e\n\u003cul\u003e\n    \u003cli\u003eMax.
