Plunger
Bendix

A precision machined plunger component constructed from steel, this element provides the essential axial translation in a range of control and actuation mechanisms within the braking system. Its small-diameter profile and defined overall length enable smooth travel within tight tolerances, reducing the risk of snagging or binding during valve or switch operation. The material choice offers reliable strength and stiffness while maintaining compatibility with high-frequency cycling applications encountered in commercial vehicles. Key benefits include predictable response, repeatable seating, and durability under thermal cycling, all of which contribute to maintaining consistent control signal transmission and valve seating in high-load scenarios. In practice, this plunger works in concert with associated springs, gaskets, and housings to ensure leak-tight operation and precise actuation. Its VMRS designation 013-010-228 places it in the cylinder and actuator segment of braking-system components, and category 42848 confirms its role within standard control hardware used across Bendix valve assemblies and related subsystems.
