ENGLISH VERSION Aggiornato 23-01-06 >

OMET proposes three ranges of complete modules aiming at satisfying the most varied needs in the field of linear motion. From the most economic to the most performing one, everything is to be evaluated according to the application. The system is composed of a pivot-pin cursor (adjustable central pin) sliding inside a C-shaped rail with inner sliding rails. The prominent features common to all ranges are: ? ASSEMBLY SIMPLICITY All the rails are provided with fastening holes so that the assembler does not have to make any further operation. If the application requires supplementary holes on...

? CONSTRUCTION PRINCIPLE OF THE CURSORS > The cursors are provided with 3 pivot-pins. The two side pins are fixed and work on a side of the rail, the central one is eccentric and therefore adjustable. It works on the opposite side of the rail. IMPORTANT > ARRANGE THE CURSOR SO THAT THE SIDE PINS LIE ON THE RAIL SIDE WHERE THE LOAD WORKS! ? SETUP OF THE CURSOR-RAIL CLEARANCE > The eccentricity of the central pin allows adjusting the pre-load and the cursor-rail clearance. PAY THE MAXIMUM ATTENTION DURING THE SETUP PHASE: TOO HEAVY PRE-LOADS DRASTICALLY REDUCE THE LIFE OF THE LINEAR SYSTEM!...

The bearings are life-long lubricated and shielded on both sides. > As to the rail type OLM-A and OLM-B (completely in aluminum) no kind of lubrication is required, since the occurring contact is plastic (bearing coating) on aluminum. For the rails type OLM-C (aluminum rail with steel insertions) it is necessary to have a lubricating film on the bars to avoid a direct contact between the metallic surfaces and protect from corrosion. The lubrication interval depends on a lot of factors among which temperature, speed and use conditions (loads, assembly of the rail so that the cursor slides...

OMET Practical TestӔ laboratory is able to carry out customized tests. The final applications of the cursor-rail system are infinite and very different from one another. − HORIZONTAL, VERTICAL AND OBLIQUE MOTIONS − TYPE OF LOADS (axial, radial, moments) − ACCELERATIONS (taking to dynamic loads due to inertia forces and creating instantaneous very heavy loads) − RAIL ARRANGEMENT, NUMBER OF CURSORS, ŢȒ USE CONDITIONS The above mentioned are only some of the features defining a linear system. Noticeably in a laboratory it is not possible to recreate all these variables; there are testing...
