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 following: robotic, handler and pick & place systems, packaging, machine tools, wood working machines, assembly machines, measure instruments, electro-medical machines, print machines.
This family of Nadella products consists of linear guides for simple installation at reasonable cost yet able to support high loads, at high velocity and function reliably in aggressive environments. The most typical applications are in the foundry industry, steel fabrication equipment, metal stamping and transfer systems, automatic storage systems and material elevators among others. The family consists of rail designs GU, FS, FSH and GP. All are cold drawn solid bearing steel with induction hardened race surfaces that can be supplied both with sandblasted or ground surface treatment. Guide rollers are executed in ball, needle or tapered roller bearing designs to offer a wide range of load capacities at various price levels. Besides the guide rollers there is the family of carriages called Rolbloc. Rolbloc carriages, designed to be used with the trapezoidal profiled rails GU, are composed of a prismatical body in steel with one or two pairs of rollers, with a cylindrical outer ring, mounted with axes perpendicular between them. With Rolbloc carriages there is pure rolling, obtained with the trapezoidal profile of GU rail, that provides a well guided system. This design allows high duty-cycle performance under heavy load capacities, high speed and low noise. Rolbloc carriages are particularly suitable for moving very heavy loads with high acceleration, for foundry and other heavy industry applications.
This family is comprised a structural element in extruded aluminium having two pressed in hardened steel shafts serving as the raceways for the rollers of the guide carriages. The combination of two materials allow us to take advantage of the main features and of production technology of both: on the one part the lightness of the light alloy, on the other part the hardness and perfect surface finishing of the steel shafts. These guide rails are designed to satisfy applications with medium/light loads and aggressive environments (wood dust and shavings). Different geometrical configurations of rails have been realised for different applications: DC: complete rail with two shafts and an aluminum body with an “I” shape. C: rail with a single shaft, to be used when greater distance between the rollers are required. FWS: complete and compact rail with two shafts. FWH: compact rail with single shaft. LM: complete rail with two shafts with “C” shape. FWN: complete rail with two shafts with interchangeable dimensions according to DIN645. Carriages contain three or more rollers of hardened and ground steel with gothic arc profile, with long life lubrication and protection shields and seals.
