Nadella by Rollon V-Line

Nadella V-Line, part of the Nadella by Rollon range, is a linear roller guide with V-shaped guide rails for industrial applications where load capacity, stability and environmental conditions are key selection criteria. The cold-drawn steel rails feature induction-hardened raceways and are available with a range of surface finishes.

The V-profile enables forces to be absorbed in various directions. In combination with matching guide rollers or bearings, this system offers possibilities for machine designs subject to significant radial and axial loads. Furthermore, the open design makes the V-Line an attractive option for applications where dust and other contaminants are present.

Which V-Line models are available?

Within this product family, Nadella by Rollon offers various models, including the FS and FSH-FSX. These models combine V-shaped guide rails with different bearing configurations. Depending on the model chosen, solutions featuring ball bearings and tapered roller bearings, amongst others, are available.

The rails are available with various career finishes, including ground versions. In addition, stainless steel materials are available for applications in which corrosion resistance is important.

Rollon also offers V-Line guide rails with an integrated rack and pinion. This may be relevant when the linear guidance and the drive are to be integrated within the same machine construction.

What to look out for when selecting V-Line?

When selecting Nadella by Rollon V-Line, the load, stroke length and available installation space are the starting point. The position of the mass center also plays an important role. An eccentricly gripping load causes moments on the guide rollers and rails. Therefore, take it with you during sizing.

In addition, the rail distance, the number of guide rollers and the selected bearing configuration influence the load distribution. Especially with heavy or variable loads, it must be assessed whether the construction remains sufficiently rigid and stable.

The speed, acceleration and cycle time also deserve attention. Dynamic forces are created during the acceleration, deceleration and change of direction of movement. The motion profile therefore partly determines which version and bearing configuration are suitable.

The mounting construction also plays a role. Correct alignment and adequate support of the rails help to limit unwanted additional loads. Therefore, judge not only the load capacity and theoretical life, but also the stiffness and movement behaviour of the total construction.

In applications with dust, chips or moisture, the choice of materials, protection of the careers, lubrication and maintenance accessibility are important. Although the V-shaped guide may be suitable for polluted environments, the operating conditions remain decisive for the necessary measures.

A suitable V-Line configuration therefore requires an assessment of load, moments, dynamics, mounting and environment. We determine which version meets the mechanical and functional requirements of the machine.
