MUGEN MRX5 Thrust Bearing Stopper (spring steel) by Arrowmax AM-MRX5-H0756  [AM-MRX5-H0756]

Thrust bearing stopper for MRX5

This Arrowmax AM-MRX5-H0756 component is an RC-scale thrust bearing stopper made for MUGEN MRX5 platforms, supplied in spring steel to resist elastic deformation under repeated loading. It serves as a compact retention element that limits axial movement of thrust bearings inside the differential or transmission stack.

In practice the stopper helps maintain bearing face alignment and reduces unwanted axial play that can alter gear mesh during acceleration or cornering. The part is intended for hobby-grade 1/8–1/10 scale electric touring and racing cars using the MRX5 chassis family where a discrete thrust retention element is required.

Installation is straightforward for users familiar with differential servicing: remove the differential assembly, locate the thrust bearing position, and fit the spring-steel stopper to provide the desired preload and axial location before reassembling. Adjustments to stack height and bearing preload should be performed incrementally and checked on the bench to verify gear alignment.
