Guide rods

Guide rods are structural components suitable for accurate and highly efficient linear guidance of the moving parts of various mechanisms. They are produced from hardened, ground and straightened circular cross section shafts and can be mounted in clamping bars, sockets and other clamping elements.

The guide rods are supplied with a relevant rolling guide according to the required operation load and type of the guide rod. Guide rods that have been properly designed, calculated and applied do not require any special supervision or maintenance. However, they should be protected against dust, water and aggressive environments.

In combination with ball screws and suitable drives they constitute basic construction motion units used in various machines and equipment.

Guide rods are usually produced from steel grades CF53 or 42CrMo4 and afterwards are induction heat treated to 58 – 60HRC.

Assembly

Before the start of operation the conservation oil layer should be removed and the guide rods should be cleaned properly. The guide rods are usually implemented with linear bushings. They should be accurately aligned in parallel with the direction of motion of the linear bearings with precision 0.02 mm/1,000 mm. In the event of any warranty repair the guide rods should be sent to the producer as a complete rolling guide assembly.

Lubrication

For the lubrication of the guide rods, suitable lubricants include those used for ball bearings as well as relevant plastic lubricants which are applied once on basis of the recommendation of manufacturers of rolling guides.
