The miniature spiral slit coupling is made of aluminum, and its high torque reaches 0.9Nm.This zero-backlash coupling has two fixing methods: tightening and fixing bolts, and can balance angular deviations of up to 3° and radial deviations of up to 0.2mm.In order to be used for higher torque and anti-corrosion requirements, this kind of coupling has also introduced stainless steel products.

　　For some smaller application spaces that cannot be used, Botou Joy Coupling also launched a smaller I series product.It is firmly fixed to the shaft by a single fixing bolt.
