Cylinder Head Bushing
Stepped bored bushing guiding the piston at the cylinder head.
Manufacturing Scope
Cylinder Head Bushing is a Hydraulic & Pneumatic Pistons family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀10–20 mm, lengths 12–28 mm, standard material Brass (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.
The family is machined from ⌀20 mm bar stock; its longest variant is HIDB-CHB-17 at 28 mm. The family is produced by turning alone. Bores in this family run ⌀6–17 mm. All of it is completed in a single setup, without the part leaving the machine.
The variant with the highest length-to-diameter ratio is HIDB-CHB-17: 28 mm long at ⌀20 mm, L/D 1.4. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to H7 tolerance; the smallest is HIDB-CHB-06 (⌀10 mm) and the largest HIDB-CHB-17 (⌀20 mm). The family includes bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
