Surface chrome plating treatment beautiful anti-rust, hardness can as high as HRC62, more durable BulletPoint3 : 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 BulletPoint4 : 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 BulletPoint5 : 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 Color : MGN9H ExternallyAssignedProductIdentifier1 : 730759342754 ExternallyAssignedProductIdentifier2 : 0730759342754 ItemName : 2Pcs HGR20-2000mm Linear Rail + 1PCS RM1605-2000mm Ballscrew with BF12/BK12 Kit, DSG16H Nut Housing, Coupling, Slide Blocks Linear Guide Rail Ball Screw Set for DIY CNC Routers Lathes Mills ItemPackageDimensions_Height : 201.93 centimeters ItemPackageDimensions_Length : 10.16 centimeters ItemPackageDimensions_Width : 11.43 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : linear-motion-guides Manufacturer : Creabygirls Material : Alloy Steel ModelNumber : 4086LZ11V3LAUY6TH0EXWU37 NumberOfItems : 1 PartNumber : 4086LZ11V3LAUY6TH0EXWU37 ProductDescription : Package & Content: 2 x HGR20-2000mm Linear Guide Rail 4 x Slide Blocks 1 x RM1605-2000mm Ballscrew 1 x Ball Nut 1 x BF12/BK12 End Support 1 x Coupling 1 x DSG16H Nut Housing
