This listing is for the blocks only. We may repackage blocks as the package is sometimes damages from the anti corrosion oil the blocks are shipped in.

Linear rail available here.

It is not recommended to disassemble blocks.  Damage to the bending fence, loss of ball bearings, or reinstallation of ball bearings to wrong side of block can occur.  Ball bearings are paired at factory to blocks according to manufacturing error and specified preload requirements. The green and red plastic parts are injection moulded and come with their own manufacturing and installation error tolerances - these may require a run-in stage. The preload on these blocks is Z0 and will not "free fall" if rail is held vertical.

Basic Dynamic Load Range: 0.68 kN - 8.93 kN

The MG series is a miniature linear guideway that comes in a compact size with a Gothic arch contact design that offers high stiffness and high rigidity against moment loads in all directions. The MG series also offers anti-corrosion protection which all material is in a special grade of stainless steel for compatibility in various working environments. The MG series is available in a narrow block type (MGN) and also with an enlarged width (MGW).

  • Precision Code: C
  • Preload: ZO (Very Light)
  • Material: Stainless Steel

MG Series - Block

  • Tiny and light weight, suitable for miniature equipment.
  • Gothic arch contact design can sustain loads from all directions and offer high rigidity and high accuracy.
  • Steel balls will be held by miniature retainer to avoid balls from falling out even when the blocks are removed from the rail
  • Interchangeable types are available in certain precision grades.

Advantages and Features of Linear Guideways

(1) High positional accuracy
When a load is driven by a linear motion guideway, the frictional contact between the load and the bed desk is rolling contact. The coefficient of friction is only 1/50 of traditional contact, and the difference between the dynamic and the static coefficient of friction is small. Therefore, there would be no slippage while the load is moving.

(2) Long life with high motion accuracy
With a traditional slide, errors in accuracy are caused by the counter flow of the oil film. Insufficient lubrication causes wear between the contact surfaces, which become increasingly inaccurate. In contrast, rolling contact has little wear; therefore, machines can achieve a long life with highly accurate motion.

(3) High speed motions is possible with a low driving force
Because linear guideways have little friction resistance, only a small driving force is needed to move a load. This results in greater power savings, especially in the moving parts of a system. This is especially true for the reciprocating parts.

(4) Equal loading capacity in all directions
With this special design, these linear guideways can take loads in either the vertical or horizontal directions. Conventional linear slides can only take small loads in the direction parallel to the contact surface. They are also more likely to become inaccurate when they are subjected to the loads.

(5) Easy installation
Installing a linear guideway is fairly easy. Grinding or milling the machine surface, following the recommended installation procedure, and tightening the bolts to their specified torque can achieve highly accurate linear motion.

(6) Easy lubrication
With a traditional sliding system, insufficient lubrication causes wear on the contact surfaces. Also, it can be quite difficult to supply sufficient lubrication to the contact surfaces because finding an appropriate lubrication point is not very easy. With a linear motion guideway, grease can be easily supplied through the grease nipple on the linear guideway block. It is also possible to utilize a centralized oil lubrication system by piping the lubrication oil to the piping joint.

(7) Interchangeability
Compared with traditional boxways or v-groove slides, linear guideways can be easily replaced should any damage occur. For high precision grades consider ordering a matched, non-interchangeable, assembly of a block and rail.
