The guide rods are an engineering element suitable to ensure the precision and highly efficient linear roller guiding of moving parts of all sorts of mechanisms. This concerns hardened and cut standard single component bars with round profiles and the ability to fix to fixing strips, sleeves, and other fixing elements.
The guide rods are supplied with appropriate roller guides according to the required operating load and design of the guide rod. Guide rods, which are correctly dimensioned and suitably used and positioned in the construction do not require special monitoring or maintenance. It is, however, necessary to protect them against dust, water, and harsh environmental conditions.
In combination with the ball screw and suitable drive, they may form the basic motion unit construction of all sorts of machinery and equipment. The rods are made of steel grades CF53 and 42CrMo4 and are inductively hardened to 58–60 HRC.
Before commissioning, the preservation film must be removed and the rod should be cleaned properly. Rolled guide rods are usually installed with linear roller bearings. The rods must be positioned in parallel with the motion of the linear bearings up to 0.02 mm per m. During removal of the guide rod for the purpose of warranty repair, the complete linear roller guide must be sent to the manufacturer.
Lubricants for roller bearings are suitable for lubricating the roller guide, and appropriate plastic lubricants are also applied one-off according to the recommendations of the roller bearing manufacturer.
