Modular Racks and Spur gears
Over the last few decades, the evolution in engineering plastics and technopolymers has led to the availability of spur gears in plastic material featuring high mechanical strengths in addition to providing all the advantages of plastic such as resistance to corrosion and chemical agents, also high resistance to torsion and good tensile strength, significant noise reduction and a low friction coefficient, which allows the use of gears even in sectors where lubrication is not recommended or even prohibited.
Elesa transmission elements can be coupled to both technopolymer and metal gears. This is an excellent solution for all those applications where it is necessary to obtain a faster dissipation of the heat accumulated during the operation.
For heavy duty applications racks are available with steel core, spur gears are provided with plain pass-through mounting holes or undrilled hubs.
