25Mm Cnc Ballscrew Kit With Anti Backlash Nut And 1750Mm Length For Nema 34 Motor Includes Bk20 Bf20 End Blocks And Coupler To Build A Rock Solid Rig Setup That Runs Slick As Butter
This CNC ballscrew kit is built for serious machine builders who need a reliable linear motion system. It includes everything required to upgrade a Nema 34 stepper motor setup into a high-precision drive. The kit features a 25mm rolled thread ball screw that slides with minimal friction. You get exact alignment between the motor shaft, coupling, and bearing supports to reduce noise and wear.
✅ SFU2504 model with 25mm diameter and 4mm lead for precise micro-feeding ✅ 1750mm total length (68.9 inch) provides ample travel range for large rigs ✅ BK20 and BF20 end blocks ensure rigid support and secure mounting ✅ 14mm coupler bore fits standard Nema 34 motors with axial alignment ✅ GCr15 steel construction offers high hardness and shock resistance ✅ C7 grade precision reduces stick-slip effect for smoother operation ✅ Integrated nut housing and bracket simplify assembly time
💡 Why choose a pre-assembled ballscrew kit over sourcing individual parts? A complete kit ensures all components are compatible and aligned correctly from the start. The integrated BK20/BF20 blocks save you from calculating complex mounting distances. Standardized dimensions like the 14mm coupler fit most common Nema 34 setups. You avoid costly errors in ordering mismatched end stops or unsupported screw lengths. This setup saves significant engineering time when building custom CNC machines. Proper lubrication every 3-6 months keeps your new rig running slick for years. Get the stability of a commercial axis with DIY assembly benefits.
