2Pcs Hgr20 300Mm Linear made for smooth installs and clean fit
✔️ 2pcs hgr20-300mm linear rail + 1pcs rm1605-350mm ballscrew with bf12/bk12 kit, dsg16h nut housing, coupling,

This 2 pack is meant for clean replacement or upgrade work where fit and smooth operation matter.

✅ Wide application: the linear rail and ball screw kit is widely used in the automation machinery such as diy cnc routers, lathes, machine tool, bending machines, laser welding machines, etc. also applicable for large-scale transmission equipment including industrial robots, cracker machines, and many other machines that need precision linear movement.
✅ High precision: motor-driven guide rail achieves high precision linear motion. designed to achieve high precision linear motion, low friction coefficient. ball screw use the ball movement with small starting torsion, it does not appear a sliding motion creeping phenomenon which can ensure accurate positioning.
✅ High-quality steel material: linear bearings made of quality bearing steel. beautiful and anti-rust surface treatment ensures durability, high hardness, and stiffness. smooth running, low noise and non-pollution.
✅ Convenience: steel support rail with pre-drilled holes for easy mounting. stainless steel linear optical axis guide bearings linear movement. easy to install, no need for maintenance.the ballscrew movement without stick-slip effect, less heats up, less drive power required.
✅ Hgr20 300mm linear guide rail and rm1605 ballscrew: this linear guide rail set includes 2 pieces of hgr20-300mm linear guide rail, 4 blocks, 1pcs rm1605-350mm ball screw with end machined, 1pcs rm1605 ball nut, 1 set bk12/bf12 end support, 1 x coupler, 1 x dsg16h nut housing.

💡 How does screw pitch change feed rate and motor torque on a CNC axis?
Quick answer: match pitch, travel length, and support style to your axis load and speed.
* Pitch controls feed rate and torque demand
* Proper end supports keep alignment tight under load
* Good lubrication cuts heat and wear over time

Built to keep motion smooth and accuracy steady during long production runs.
