Knurled Shaft Coupling
Shaft coupling element with knurled grip and internal thread.
Manufacturing Scope
Knurled Shaft Coupling is a Couplings & Shaft Adapters family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀8–20 mm, lengths 20–42 mm, standard material Aluminium (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 KAPB-TML-10 at 42 mm. Besides turning, the family requires knurling. Bores in this family run ⌀3–12 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 KAPB-TML-01: 20 mm long at ⌀8 mm, L/D 2.5. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to h9 tolerance; the smallest is KAPB-TML-01 (⌀8 mm) and the largest KAPB-TML-10 (⌀20 mm). The family includes knurled, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
