Product Overview:
The NeveRest is a gearbox and motor combination with an attached encoder designed with FIRST Tech Challenge teams in mind, by including geometry that matches existing bolt patterns. The shaft is 6mm in diameter and the gearbox housing is 37mm in diameter. The power cable which feeds into the black encoder housing for the motor has two powerpole connectors already crimped to the end of the cable making the gearmotor or motor by itself, ready to use.

Product Usage Note:
We have received some feedback from a small number of customers regarding the durability of the gearbox on the NeveRest Classic 20 Gearmotor. After some internal testing, as well as review of returned gearmotors, we have found that this particular gearbox is more susceptible to failure from shock loads as compared to the NeveRest Classic 40. These sort of failures happen most commonly in high-shock applications such as flywheel shooters, as well as drive chassis. We recommend these gearmotors to be used in low shock-load applications such as intake rollers, internal conveyors, etc.
