Nadella Guide Rollers

Product Details

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. Their 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. Linear guide systems for heavy loads 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.NADELLA provide a wide range of guide rollers to be able to meet different technical and economic requirements. All guide rollers are produced in concentric and eccentric versions to allow backlash adjustment during assembly on final equipment. Eccentric rollers are identified by additional R in the code.The sides of the races of the guide roller are slightly convex. Besides reducing rolling friction, this also permits offsetting slight guide flexing or small assembly alignment errors.Guide rollers are fitted with seals or shields for bearing protection and lubricant retention as described in dimensional tables.Guide rollers based on needle or tapered roller bearings (FRN ... EI, RK ..., PK ...) are recommended for critical applications with heavy axial loads and / or shock loading. Guide rollers based on ball bearings (FR ... EU, PFV, RCL) are more suitable for lighter loads or high dynamic systems.The carriages based on Rolbloc's system are recommended for applications with heavy loads, high frequency of work and aggressive environment (dust, abrasive).When mounting guide rails opposite to each other with connected carriages, as shown in the next sketch, a high level of parallelism between the guide rails is required when axially rigid rollers are used. To avoid operating problems, it is recommended to use axially rigid fixed rollers on one carriage e.g., FR ... EU / FRR … EU and axially movable rollers on the other carriage e.g., FRL ... EU / FRLR ... EU. Movable rollers allow a little misalignment between the opposite mounted guide rails.NADELLA Guide Rollers Series RKU FKU FR FRR FRN FRNR FRLK FRLRNADELLA Guide Rollers RKY RKYR FKY PK PKR FK PFV PFVR RKO RKOR
