• Ball screw diameter: 25mm; Lead / Pitch: 5mm; Total length: 80.71 inch / 2050mm; Nut + BK20 integrate with Motor Bracket for stepper motor Nema 34/BF20 End support with locknuts and circlips + Flexible coupler + Ball Screw Nut Housing. The diameter of the coupler which matches the motor shaft is 14mm in default, if your size is other, pls tell us
• The ball screw kit can ensure motor shaft, coupling axial, axial bearing hole, and screw axis all in a line strictly, to make the transmission system run more accurately and sturdily, less noise and longer life. The material of the bk bearing support and Motor Bracket is cast steel, high hardness, shock resistance and high precision machining
• The ballscrew is no stick-slip effect, heats up less, reduce driving power required, small starting torque, able to apply high speed and micro-feeding
• 2Pcs linear rails HGH25 25mm length: 80.71 inch / 2050mm, 4Pcs HGH25-CA bearing slider carriage blocks. Strong bending resistance, difficultly deformed and twisted, ensuring precise linear motion, have high accuracy of the trajectory
• Innovative slider technology, smooth, low friction, high speed and silent operation. Can withstand the load in all directions with four-direction equal load characteristics and self-aligning to absorb installation-error
