y. Reducing friction by up to 50% compared to conventional systems, the TR 200 exhibited minimal wear after 15 million cycles. Its dynamic sealing function is achieved by a sealing area with a large radius. Radial sealing force is created by a design interface that eliminates the radial compression of the seal cross section, which minimizes friction and wear while also eliminating stick-slip effects.
Another recent development from Simrit combines the advantages of elastomer and PTFE materials to produce two low-energy seals with low initial friction, non-linear behavior, and low hysteresis. The TCS is a bonded piston specifically developed for reciprocating motion. It combines the low friction characteristics of PTFE with the rigidity, centering, and lip shape (similar to that of a channel gasket) of a bonded transmission piston seal with the metal carrier that was previously used. The TCS tolerates high temperatures, involves mounting of a single part, has an integral piston, and offers excellent centering.
The third is Simrit’s TCS, a general-purpose piston groove seal offering low coefficient of friction and high heat tolerance. It features dual layers, including PTFE foil enhancement. Developed for use as a D-ring in a wide range of designs and diameters, the seal does not twist, resists extrusion and is easy to install.
