• 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.
• SPECIFICATIONS: The linear rail length: 800mm/31.5 inch, diameter:20mm/0.79 inch; Ball screw diameter:16mm/0.63 inch, ball screw pitch:5mm/0.2 inch, ball screw length: 800mm/31.5 inch.
• CONVENIENCE: Aluminum alloy support rail with pre-drilled holes for easy mounting. Stainless steel Linear optical axis guide bearings linear movement.The ballscrew movement without stick-slip effect, less heats up, less drive power required.
• HIGH PRECISION: Industrial-Grade standard linear rails with high precision. Ballscrew use the ball movement with small starting torsion, it does not appear a sliding motion creeping phenomenon which can ensure accurate positioning.
• COMPLETE LINEAR RAIL AND BALL SCREW KITS: This linear rail set includes 2 pieces of 800mm rail shafts and 4 SBR20UU blocks.This ball screw kit includes 1 x SFU1605-800mm ball screw end machining, 1 x ball screw Nut,1 set BK12/BF12 end support,1 x coupler, 1 x nut housing.
