Rolled and ground ball screwsA wide range of ball screws made in Italy
TRM offers a wide range of ball screws made in Italy by the company Scaravella.
In business for more than 60 years
Scaravella has been producing rolled and ground ball screws since 1975, either from a catalogue or to customer specification.
A complete catalogue
The Scaravella catalogue contains more than 1,000 types of nuts: cylindrical, cylindrical with threaded head, standard flange, DIN and customised flange, made for ball screws.
100% Made in Italy
Production is entirely made in Piacenza, Italy, with high quality materials, selected and processed by Scaravella with modern machinery.
Accurate measurements
All Scaravella products are 100 per cent guaranteed and tested with sophisticated measurement systems, capable of intercepting even the smallest deviations from standards and/or design specifications.
Production of linear guides and blocks
TRM manufactures linear recirculating ball linear guides and carriages for applications in automation and robotics, machine tool production, measuring systems, medical technology and food technology.
Linear guides offer the possibility of load positioning systems in combination with drive elements such as actuators or ball screws. The linear range includes precision industrial linear guides with different design geometries, loads and construction characteristics to suit each individual application. TRM linear guides and carriages are high-quality components for applications requiring low friction and low noise.
Linear systems with rails and carriages are used in many fields of application, can provide high load capacities and ensure friction-free running, with mounting methods that can also facilitate installation and maintenance.
