- Offer Profile
- Nadella was founded, with the
name of Nadella Cuscinetti S.p.A., in 1963 as the Italian branch of a French
manufacturer of needle bearings.
The traditional commercial activity of Nadella consisted in sale of needle
bearings produced in French, after that new interesting lines of products
were developed. These products are mainly linear guide systems, linear
actuators, adjusting nuts and angle gear boxes. Design and production of
linear guide systems are not only oriented to standard products, but also to
custom solutions for specific customer applications.
Linear and Motion Solutions
Linear Guide Systems
- Nadella is specialised in the design and production of
linear guide rail and rollers, divided into heavy and light load families,
suitable for all applications where high speed and low noise are required
and the operating environment is very aggressive.
Our rails can be supplied with a single length of 6 meters, can be cut and
drilled according to the customers’ needs and can be jointed together.
The main application fields of Nadella’s linear guide systems are the
- Robotic, handler and pick & place systems
- Machine Tools
- Wood Working Machines
- Assembly Machines
- Measure Instruments
- Electro-medical Machines 8.
- Print machines
- The adjusting locking/unlocking nuts and rings are used
whenever precision mechanisms require a precision clamping as well as a
powerful and safe locking, but above all for adjusting and clamping all type
of bearings. The original clamping system is constituted from a part of the
threaded section of the adjusting nut or ring (threaded clamping spring).
When tightening the hexagon grub screws clamping is applied with a very
strong pressure onto the threaded spring which meshes perfectly into the
corresponding threads of the shaft or spindle. The Nadella adjusting nuts
and rings can be easily mounted, dismounted and reused without losing the
- Nadella telescopic slides are special ball bearing guides
for high load rating. Two or more ball bearing mounted guide rails which can
be drawn telescopic wise guarantee a high reliability. According to the
requirements a combination of different manufactured parts are used. Load
and extension proportions are the basic characteristics of the telescopic
The model line is made up of five types and three extension proportions:
part extensions, full extensions, full extensions in Z-design, heavy duty
extensions and over extensions.
- Nadella’s linear modules are an integrated product. The
aluminium extruded profile of high rigidity contains linear guidance and a
belt drive system which allow high performance in any application, with a
single module or in multi-axes configurations. The four available sizes (AXN
45 / 65 / 80 / 100) make use of our roller guide system (rollers of large
dimensions with double ball cages, lubricated for life), and hardened and
ground steel shafting pressed into the aluminium profile. For the drive
system a toothed belt in polyurethane with steel tension cords rolls on two
steel toothed pulleys located in the heads of the module. An integrated
lubrication system, easily accessed on the carriage, facilitates lubricating
the contact area between the rollers and the shafts. The roller guide system
allows high speed motion (up to 10 m/s), at low noise levels. Nadella offers
complete systems including connecting shafts, motor flanges, couplings,
limit-switches, T-slot nuts, fasteners and connecting plates.
Needle Roller Bearings
- Needle bearings are a standard element of a rotational
motion system. Needle bearings are used in applications where high load
capacity, high precision and small overall dimensions are required. Nadella
offers a big range of needle bearings. The strength of Nadella’s production
consists also in the ability of producing special items at a reasonable
price. Every bearing contains the long experience acquired from Nadella
through decades of design, production and application.
