Turned from certified C45 bar, these bushings carry an induction-hardened bore at 58-62 HRC, ground and lapped to Ra 0.8 with H7 fit held across the full length. Concentricity stays inside 0.008 mm so the part drops into serviced housings without re-boring.
Wall sections, flanged heads and spiral oil grooves are standard options machined on the same setup. Trial pieces ship with dimensional reports, and mixed lots are kitted by fit grade for direct-line assembly.
- Hydraulic cylinder guide bores
- Linear shaft bearing interfaces
- Gear and pump wear bushes
- Pivot points in linkages
