BEISGUANGS Electric Bike Accessories Universal Torque Arm Conversion Kit for ebike Front or Rear Hub Motor Wheel E Bike kit Easy Install Reinforcement
【Material】Torque arm is made of high-quality metal, with good design and strong resistance to deformation. The surface is galvanized to prevent corrosion and maintain gloss..
【Size】Torque arm length 86mm, shaft hole 14mmX10mm, C clip 14mmX10mm, arm thickness 3mm, hub bracket thickness 4mm, C clip thickness 3mm, can be adjusted according to different configurations..
【Function】This torque arm will help prevent the motor from loosening from the bicycle's front fork (front) or frame (rear fork), and prevent the slotted shaft from bending or breaking your dropouts. Necessary for high-power motors..
【Installation】This torque arm is suitable for electric bicycle motors and electric bicycle conversion kits. Easy to install, the product is suitable for normal motor shafts, except for special shafts (the size of the motor shaft does not exceed 14mm)..
【List】Contains 1 long reaction arm + 1 short reaction arm + 1 hex screw + 1 collar + 1 nut + 2 washers. (as the picture shows). It can provide maximum protection for your electric bicycle, motor and hub motor wheel..
Witproton Ball Splines with One End Stepped 10mmX300mm 1pc
Low friction: the ball does not circulate, and it can achieve rolling motion with minimal friction..
It can perform high-precision linear motion: as a component of the shaft and the nut, the gap in the rotation direction can be adjusted to ensure accuracy..
Rotating torque can be transmitted: the ball rolls on the ball groove of the spline shaft, and it can move linearly while transmitting the rotating torque..
Compact design: Even with a single-axis mechanism, it can move linearly while keeping the nut in the direction of rotation without deviation..
Large load capacity and long service life: Because the rolling surface is made of R-shaped ball groove in line with the diameter of the ball, the contact area is large, the load capacity is strong, and the service life is long..

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..

Straight miter 90 degree mesh transmits mechanical power between perpendicular shafts.
Pressure angle of 20 degrees for a lower contact ratio between gears, resulting in higher load capacity than smaller pressure angles.
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.
