V-LINE System

The name “V-line” comes from the V-shape of rollers and this is a robust and reliable system for all applications where smoothness and load capacity are required. V-Line system combines the versatility of the rollers with an excellent level of precision.

The rails are available in steel and stainless steel, with hardened raceways in order to ensure high durability both in traditional applications and for specific sectors such as food, pharmaceutical and medical, in which the research of materials makes Nadella a reference partner for the main machine manufacturers in the worldwide.

The guide rollers with V-groove profile can also be supplied with special lubricants (FDA approved, Vacuum, High Temperature, ...), required for compliance with food regulations or to guarantee correct operation even in the most critical conditions.

The FS rail has a double sliding cusp which allows it to work also as a single monorail, while the FSH (Half) rail allows you to space the rollers in order to increase the load capacity, ideally covering any size the customer may require to cope with high bending moments or special conditions.

FS and FSH rails are available with different surface finishing, sandblasted or grinded, the -M guides can also be used in applications with high precision or in the presence of high vibrations.

The range has 9 sizes available in stock with length up to 6 m, with the possibility of jointed rails for longer strokes.

The guides are supplied with standard or special boring layout according to catalogue or to customer drawing, thanks to Nadella's production versatility: Custom Made is one of the most recognized Nadella strengths.

From the profile of the FS, the FSR was born: a series of circular rails used both in standalone sectors and to make oval circuits in machinery with repetitive cycles, such as packaging, pick & place or medical.
Today our FSR is also available in the motorized version AXNRO and AXNRQ.

Do not forget the rails with integrated rack, where the assembly and alignment of a FS guide with a traditional rack make the FSHZ the most compact and convenient solution for the construction of machines with long strokes.

The guide rollers with V groove are available in many executions in order to fit with different load configurations and the various assembly needs:

• The Nadella classic roller FRN, with needle bearings;
• The Nadella best seller FR..EU, with double-rows of ball bearings;
• The RKY, for more demanding applications and high axial loads, with double crown of tapered roller bearings.

All the rollers are available in concentric and eccentric (-R), fixed or floating (-L) versions to ensure clearance-free mounting, allow preload adjusting and recover small misalignment errors in assembly.

Just as for the rails, a range in stainless steel (-NX) is provided, available from stock for the ever-increasing applications that may require its use.

In addition to the standard executions available in the catalogue, Nadella's Technical Office processes numerous special requests every day (for shape and size, materials, surface coatings, ...) in order to meet the most several needs of engineers, always looking for the most suitable product for layout of the machine they design.
