Best Hexagonal Shaft Torque Limiter Coupling

Heyiarbeit 5pcs 4mm to 4mm 2 Section Rotatable Universal Joint Coupling Shaft Stepper Motor L52xD12 U Joint Coupler Connector with Screw for RC Model Motor, RC Robot, DIY Encoder, CNC Machine

[Total Size] - Outer Diameter: 12mm / 0.47".
Connection Diameter: 4mm to 4mm / 0.16" to 0.16".
[Material] - This universal coupling is made of premium iron metal material, which is durable and has a long service life, fine workmanship.
[Feature] - The universal joint of the purpose is to firmly connect the driving shaft and the driven shaft to rotate together and transmit motion and torque, cost effective coupling design, which is very flexible and easy for use, and is great replacement for your old or broken one.
[Design] - Rotatable design. Allow the angle between the two axes within a limited range vary with operational needs, and easy to set up the items on the shaft and control the holding capacity of the coupling.
[Wide Application] - Universal joint coupling are used in servo motor systems, 3D printer, cnc machine, diy encoder, spindle transmissions, stepping motors, lifting platforms, machine tool transmissions, stepping motors, encoders, screw drives, machine platforms or gearboxes, etc.
Great suitable for short support shaft, bushing model, miniature Shaft, model airplane/ boat/ car.

Size:L25mm x D20mm/0.98inch x 0.79inch( L*D) Bore Diameter: 5mm to 8mm / 0.19inch to 0.31inch.
Shaft Coupler Material: Aluminum alloy, Surface oxidation treatment.
Super torque can absorb vibration, appropriate a large torque transmission.High hardness,Durable,and excellent response,not easy to loosen.
Flexibility of coupling shaft removes stress between the motor and driving components, The coupling can be disassembled and used in combination by itself.
The shaft couplers are mainly used for CNC machines,servo motors, spindle, step motor etc.

【Dimension】 - Shaft usage:12mm to 15mm/0.47" to 0.59".
【Material】 -The coupling is made of aluminum alloy, the surface is oxidized, and the type isthread holding tight.

Connection Diameter: 10mm to 10mm, Total Length: 22mm /0.87 inch, Outside Diameter : 16mm/ 0.63 inch.
Widely used in blowers,3D printer,DIY robots,CNC machine,stepper motors,etc. Similar to rigid clamp couplings, shaft couplers are used to hold bearings and sprockets tightly on the shaft, and are used in motor and gearbox assemblies..
Top tight type rigid coupling with 2/4 screws to hold the shaft tightly.
high torque with rigidity, low inertia and excellent sensitivity..
NOTE: The rigid type basically does not allow eccentricity, and it must be fully adjusted during use..
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..
