Nadella Guide Rollers

About Nadella Guide Rollers

Nadella is specialized 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 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).

Engineered Durability and Precision

Nadella Guide Rollers are manufactured from high-quality alloy steel that undergoes heat treatment and precision grinding, resulting in superior hardness, strength, and corrosion resistance. With options for single or double rows and different roller or bearing types, they accommodate diverse operational demands, ensuring stability and longevity for automation, linear motion, and material handling equipment.


Wide Operating Range and Versatile Sealing

Designed to perform in temperatures ranging from -20C to +120C, Nadella Guide Rollers are suitable for both indoor and challenging outdoor environments. The choice between double rubber seal (2RS) and shielded (ZZ) types provides flexibility for applications requiring enhanced protection against contaminants or reduced friction for higher speeds.
