Rosa Linear Bearings

Product Details

Rosa Sistemi - MG linear guidesMG Monoguide Series  Many types of modern industrial machines, especially machine tools, require linear guidance systems with high precision and rigidity, low heat generation and vibration, compactness and a wide range of configurations. All Rosa Sistemi linear guides meet these requirements, in particular the MG Monoguide series of roller guides.  Rosa Sistemi NG Linear Guides Rosa Sistemi Srl high precision prismatic linear guides Rosa Sistemi Srl designs and manufactures Prismatic Linear Guides, which are high precision linear motion products, ideal for use in a wide range of machine tools, machining centres, material handling systems and special machines, as well as in measuring and testing equipment.  GR prismatic linear guides with crossed rollers or balls This type of guide is designed for rollers and balls. Rollers have the advantage of a much higher load carrying capacity. On the other hand, balls have the advantage of lower running forces, are less sensitive to contamination and can better compensate for deficiencies in the adjacent structure.  NG Prismatic LM Guide with Cross Rollers This type of product represents the modern evolution of the GR type of guideway and consists in creating guideways which, despite their smaller section, have better characteristics in terms of load capacity and therefore rigidity. This new type of LM Guide, called NG, also has two different sections with standard dimensions ranging from 50 to 400 mm in length, 19 to 25 mm in height, 9 to 12 mm in width and 27 to 368 g in weight.  RM/RV Prismatic LM Guide with Needle Rollers and Cage The same calculation criteria used for the GR model are used for the RM/RV model. However, it is necessary to take into account the different characteristics of the GR type rail: - Higher load ratings. - Higher rigidity. - Better roller overlap, especially with short strokes. - Greater sensitivity to installation errors and contamination. M/V prismatic linear guides with special coated sliding surfaces The M/V Prismatic LM Guides are coated with a special sliding material on the sliding surfaces and retain the same characteristics as the RVA models. The dimensions are the same as those of the GR type, but the rigidity of the system is significantly increased. These slides are mainly used to eliminate vibrations in the system.  RM/RVA prismatic linear guides with sliding track coating This type of guidance system complements the RM/RV guidance system. The rails of the RVA are coated with a special anti-friction material. This type of guidance system is used for relatively low speeds (max. 20 m/min) and critical system stiffness. A set can consist of two RM guides and two RVA guides. The RVA and RV guides are interchangeable in size.  GRD double raceway prismatic linear guides The GRD dual raceway prismatic linear guides have been designed to simplify system assembly and increase system rigidity. These prismatic guides can be used with the top of the TR and TRL linear coordinate tables to increase cost efficiency. GRD guideways are an integral part of TRKD systems equipped with RK ball recirculating carriages.  RK ball recirculating linear unit The RK linear units with ball recirculation consist of three main parts. The first is a hardened steel central housing (hardness HRC 60 ± 2) to support the load. The balls travel along the V-shaped raceway of the LM rail and are retained by a polyamide block that prevents them from falling out and provides directional control. Ball units combined with GR or GRD slides provide linear motion limited only by the length of the slides themselves.
