Solid laminated gaskets SLA, designed in order to replace the traditional liquid sealants, avoid any accidental leakage occurring between housing and side covers and also inappropriate polymerization.

Coupling spider in a new optimized geometry by FEM simulation, made in an enhanced polyamide with a special elastomeric insert, an advanced powerful polymer compared with traditional TPU and TPE thermoplastic elastomers.

In 2006, Varvel introduced a valuable and upgrading feature to the 'flexibility evolution': the strategic road map of the company's development in years to come. The usual key-coupling between motor and gearbox was replaced by a customized type "G" flexible coupling without any increase in the geared motor dimensions.
