Oldham Coupler 5x8

Product Description This is the go-to coupler for the Z-axis motion of the Wuxn WXR 3D printer. Oldham couplers join two non-coaxial shafts to transfer torque. Product Features Oldham couplers are designed with a floating center disk for angular misalignment compensation, providing zero backlash to ensure precise positioning. The disk also offers a degree of vibration damping, and separate when linear motion systems are binding due to mechanical misalignment or collisions.
