LINEAR RAIL KITS: 2 pieces of linear rail 1000 mm/39.37" long rail shafts and 4 Pieces SBR12UU blocks. Sliding blocks to be used cooperatively with rails..
EASY TO INSTALL: Aluminum support rail with pre-drilled holes for ease of mounting.Suits X, Y, Z axis..
ADVANTAGE: Premier Linear Guiding System.The support rail unit provides maximum rigidity and stiffness to the shaft throughout the whole stroke, and ensure the performance of the unit..
HIGH-QUALITY STEEL MATERIAL: CNC parts linear rails are made of carbon steel, linear bearings are made of quality bearing steel with aluminum alloy housing. Surface chrome plating treatment makes it anti-rust, durable, and extremely hard..
WIDELY USED: It is widely used in linear motion system. Such as, punch, tool grinding machine, automatic cutting machine, printer, card sorting machine, food packing machine, other sliding parts on industrial machinery..

Low friction: the ball does not circulate, and it can achieve rolling motion with minimal friction..
It can perform high-precision linear motion: as a component of the shaft and the nut, the gap in the rotation direction can be adjusted to ensure accuracy..
Rotating torque can be transmitted: the ball rolls on the ball groove of the spline shaft, and it can move linearly while transmitting the rotating torque..
Compact design: Even with a single-axis mechanism, it can move linearly while keeping the nut in the direction of rotation without deviation..
Large load capacity and long service life: Because the rolling surface is made of R-shaped ball groove in line with the diameter of the ball, the contact area is large, the load capacity is strong, and the service life is long..

Made of Bearing Steel , move smoothly without deflection high accuracy minimal wear and low noise..
Applied in semiconductor manufacturing equipment, printed circuit boards, IC assembly equipment, medical equipment, robotic arms, precision measurement machine and other small linear motion device..
It worked great and had no resistance in the bearings when put on a rail ease of mounting..
The system works beautifully for both slider motion as well as panning..
Package include:1PC MGN9C 200mm Linear rail guide ,1PC MGN9C block..
