Twotrees MGN12H 350mm Linear Rail Guide Linear Sliding Guideway with 1pcs Linear Bearing Sliding Block for 3D Printer and CNC Machine(H-Type,Black)

• 350mm MGN12 linear rail guide with MGN12H block
• Suggested to use M3 T nut and screws if you fix it to 20 series EU Al-profile
• High Quality:Made of Bearing Steel with low friction coefficients.It worked great and had no resistance in the bearings when put on a rail.And it works beautifully for both slider motion as well as panning.
• Widely Use:Applied in semiconductor manufacturing equipment, printed circuit boards, IC assembly equipment, medical equipment, robotic arms, precision measurement machine and other small linear motion device.
• Several lengths available: 300mm, (12 holes), 350mm, 14 (holes), 400mm, (16 holes), For connecting the rail to the machine via M3 bolts and nuts.
