Reviews 2 pc Shaft Low Torque

Boston Gear HLSK103YL Spiral Miter Gear, 35 Degree Spiral Angle, 1:1 Ratio, 0.750\ Bore, 10 Pitch, 20 Teeth, Steel with Hardened Teeth

Left hand spiral miter 90 degree mesh transmits mechanical power between perpendicular shafts.
Spiral angle of 35 degrees better suits this spiral miter gear for higher speed and larger torque applications than straight miter gears.
Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion.
Hardened teeth for 1:1 gear ratio applications where hardness and strength are needed to transmit torque and motion.
Bore has keyway and setscrew for use with keyed shaft.

Total Length: 22mm/0.87 inch, Outside Diameter : 14mm/0.55 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..

Connection Diameter: 4mm to 4mm, Total Length: 26mm /1.02 inch, Outside Diameter : 10mm/ 0.39 inch.

【Dimension】 - Shaft usage:17mm to 17mm/0.67" to 0.67".
【Material】 -The coupling is made of aluminum alloy, the surface is oxidized, and the type isthread holding tight.
【Features】- Connector is wear-resistant, high hardness, good responsiveness, super elastic torque can absorb vibration, suitable for large torque transmission.
【Function】 -The Flexible Coupler Joint transmits torque while suppressing system vibration and adapting to misalignment to protect other components from damage.
【Application】 -The shaft couplers are mainly used for CNC machines,servo motors, spindle, step motor etc.

Product 1: Includes: 1-pc. 3/8 in. drive torque wrench.
Includes product manual with torque conversion chart.
Product 1: Wrench emits a click that can be heard and felt when the preset value is reached.
Product 1: High-contrast dual-range scale is easy to read, even in low light.
Product 1: Reversible ratchet head drives in both directions and measures torque in clockwise direction.
Product 2: Confidently tighten fasteners to a manufacturer's torque specifications, preventing expensive damage caused by overstressed or poorly secured Parts.
Product 2: Wrench emits a click that can be heard and felt when the preset value is reached.
Product 2: Smooth and precise, the spring-loaded adjustment collar automatically locks in place at the desired torque value, ensuring it won't accidentally wander during use.
Product 2: Reversible, finely geared 72-tooth ratchet head measures torque in clockwise and counterclockwise directions for regular and reverse threaded fasteners.
