DHS Equipment sources this part directly through authorized channels, so you can order with confidence knowing you're getting the correct component for your machine.
Key Features
- Genuine OEM Construction — Manufactured to the exact dimensional tolerances required for the ST45 bushing application, maintaining proper clearance and load distribution within the assembly.
- Direct-Fit Replacement — Engineered to install in the same position and orientation as the original, with no modification to surrounding components needed.
- ST45 Compatibility — Confirmed fitment for the Multiquip ST45 swing tube concrete pump series.
- Wear Resistance — A correctly functioning bushing reduces metal-to-metal contact at pivot and bearing points, protecting adjacent components from accelerated wear.
- Maintains Pump Integrity — A worn or failed bushing introduces unwanted play into the pump's mechanical linkage, leading to misalignment and increased stress on surrounding parts.
A bushing serves as a load-bearing sleeve that reduces friction and wear between two moving or mating components. In a concrete pump like the ST45, bushings are critical at pivot points and mechanical joints where repeated motion and heavy loads are transferred through the machine's structure. When a bushing wears beyond its service limit, excess play develops in the joint, causing misalignment, vibration, and accelerated damage to surrounding hardware — making timely replacement essential to keeping the pump operating correctly.
