Nexen rullapyöräjärjestelmä RPG sisältää pantentoidun pyörän sekä hammaskehän tai hammassegementin. Hammaskehät ja -segmentit on saatavilla joka sisä- tai ulkopuolisella hammastuksella.
Avain ominaisuuksia
RPS-GP hyödyntää samaa teknologiaa, mutta se on valmiiksi laakeroitu. Tämä tarkoittaa, että sillä voi suoraan korvata perinteiset kääntökehät. RPS-GP tuo samalla järjestelmään nollavälyksen.
Nämä tuotteet mahdollistavat myös voiteluvapaan toiminnan ja +/- 13 ArcSec paikoitustarkkuuden sekä +/- 1,6 ArcSec toistotarkkuuden.
Maksipyöriminopeus 632 rpm.
Nimellismomentit 2625 Nm asti ja maksimimomentti jopa 4313 Nm.
