1set Rigid Shaft Coupling CNC Motor Jaw Shaft Coupler Connector Sleeve #45 Steel Transmission Connector(8-8mm)

CouplingsThe rigid coupling is 90 degree fastening design, and is fastened by four machine screws.It is Steel No. 45, not stainless steel, it is a kind of iron, but it is harder than ordinary iron.#45 Steel material, aperture error is ±0.05mm, through-hole design, two aperture lengths each account for half of the coupling!The shaft coupler connector is mainly used to connect the shaft of the motor and the Fully Threaded Rod to ensure the normal operation of the machine.Mainly used for 3D printers, DIY model cars, model boats, model Airplane.NOTE: The rigid type basically does not allow eccentricity, and it must be fully adjusted during use.Top tight type rigid coupling, high with rigidity, low inertia, and excellent sensitivity.No rotation gap and elastic action can make up for symmetrical angular misalignment.Single piece set screw clamp design makes it easy to set up the items on the shaft and control the holding capacity of the coupling.Package include:Coupling*1+ machine screw*4+wrench*1(Only one wrench is delivered per order.)Size description: For example, 5mm-7mm indicates that one side has a hole diameter of 5mm and the other side has a hole diameter of 7mmThe coupling length is 22mm(Among them, the length of 3mm-3mm is 25mm)There are three kinds of outer diameter according to different apertures: 14mm, 16mm,18mm1,The following 1 kinds of couplings are 14mm in outer diameter and 25mm in length:3mm-3mm2,The following 26 kinds of couplings are 14mm in outer diameter and 22mm in length:3mm-4mm,3mm-5mm,3mm-6mm,3mm-8mm,3.17mm-5mm,3.17mm-6mm,3.17mm-8mm,4mm-4mm,4mm-5mm,4mm-6mm,4mm-7mm,4mm-8mm,5mm-5mm,5mm-6mm,5mm-7mm,5mm-8mm,6mm-6mm,6mm-7mm,6mm-8mm,6.35mm-5mm,6.35mm-6mm,6.35mm-6.35mm,6.35mm-8mm,7mm-7mm,7mm-8mm,8mm-8mm.3,The following 6 kinds of couplings are 16mm in outer diameter and 22mm in length:5mm-10mm,6mm-10mm,6.35mm-10mm,7mm-10mm,8mm-10mm,10mm-10mm.4,The following 6 kinds of couplings are 18mm in outer diameter and 22mm in length:5mm-12mm,6mm-12mm,6.35mm-12mm,8mm-12mm,10mm-12mm,12mm-12mm.==========High-concerned chemical : NoneStandard or Nonstandard : StandardFlexible or Rigid : FlexibleModel Number : 3/4/5/6/6.35/7/8/10/12mmMaterial : #45 SteelStructure : Metal BellowsOrigin : Mainland Certification : None
