Flexible Couplings
It is Steel No. 45, not stainless steel, it is a kind of iron, but it is harder than ordinary iron.
The coupling length is 22mm
There are two kinds of external diameter according to different apertures: 14mm, 16mm
The rigid coupling is 90 degree fastening design, and is fastened by four machine screws.
Pure copper material, aperture error is 0.03 mm (basically negligible), through-hole design, two aperture lengths each account for half of the coupling!
Size description:
The following 6 kinds of couplings are 14mm in diameter and 22mm in length.
4-4, one side aperture 4mm, the other end aperture 4mm; (side hole M4 machine screw)
5-5, one side aperture 5mm, the other end aperture 5mm; (side hole M4 machine screw)
5-8, one side aperture 5mm, the other end aperture 8mm; (side hole M4 machine screw)
6-6, one side aperture 6mm, the other end aperture 6mm; (side hole M4 machine screw)
6-8, one side aperture 6mm, the other end aperture 8mm; (side hole M4 machine screw)
8-8, one side aperture 8mm, the other end aperture 8mm; (side hole M4 machine screw)
The following 3 kinds of couplings are 16mm in diameter and 22mm in length.
