OMET LINEAR MOTION ENGLISH VERSION Aggiornato 23-01-06

THE PHILOSOPHY OF “OMET LINEAR MOTION” 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...

OLM-C SYSTEM • Code T,6002,…. RAIL SECTION 30 mm • Code T,6003,…. RAIL SECTION 40 mm MATERIAL: Realized by coupling a supporting element in aluminum alloy with steel bars that make up the sliding surfaces. In such a way the most favorable features of both materials and the relevant processing technologies come to meet: the lightness of the alloy and the surface wear resistance of the bars. The rails in this family can fulfill structural functions; the high inertia moment allows using them as carrying structures in many accomplishments. The extruded aluminum profiles are stabilized and...

BALL BEARINGS FOR RAILS OLM-C In order to meet with the variety of applications and allow the customer a larger customization possibility, OMET also proposes single components, leaving up to the designer how to make the most suitable cursor for one’s own application.

GENERAL INSTRUCTIONS FOR USE • 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. • SETUP OF THE CURSOR-RAIL CLEARANCE The eccentricity of the central pin allows adjusting the pre-load and the cursor-rail clearance. How to set: The adjustment of the eccentric pins shall be carried out rotating the shaft counterclockwise. In such a way any vibration that may occur during working will tend to tighten the...

LUBRICATION • BEARING LUBRICATION The bearings are life-long lubricated and shielded on both sides. • RAIL LUBRICATION 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...

CUSTOMIZED LOAD TESTS OMET “Practical Test” 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, … - 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;...
