Nadella specializes in motion technology products such as linear guide systems, bearings, cam followers, and telescopic rails. The Hardened Telescopic Line is noted for its high load capacity and durability, ideal for heavy-duty applications.
Telescopic rails are available in sizes 28, 33, 43, with size 63 coming soon. Made from cold drawn steel with induction hardened raceways, they ensure smooth movement and reduced friction. The product line includes full extension rails (NTS-H), part extension rails (NTA-H), and linear guide rails (NTSF).
- High load capacity and low deflection
- Induction hardened raceways for wear resistance
- Steel ball-cage for smooth sliding and high load capacity
Nadella has a worldwide network of sales engineers and distributors, providing customer-oriented solutions and excellent service delivery.
Standard material is zinc-plated steel, with options like NC4 zinc-nickel alloy coating available upon request.
Proper lubrication is crucial, with re-lubrication recommended every 50,000 cycles. Operational temperature ranges from -20°C to +120°C, with a maximum of 170°C. Higher temperatures may reduce load capacity.
Load capacities are specified for single sliders in Newtons (N) and Newton-meters (Nm). Proper assembly involves mounting guides in parallel and using all available holes for uniform load distribution.
The lifetime of the guide rail is determined by the maximum stroke or number of cycles before plastic deformation occurs, based on dynamic load capacities and equivalent loads.
Deflection refers to the elastic deformation at the rail's edge when a load is applied.
For optimal performance, guides should be mounted with two parallel guides, with the load applied in the middle of the sliders. The ball-cage system ensures smooth sliding by moving the ball-cage half the stroke of the slider.
Discusses the displacement process of ball-cages in relation to slider position, leading to stroke reduction and dragging on raceways. It is advised to use the race for the entire stroke and limit speed and acceleration.
Ball-cage guide systems are recommended for horizontal movements. An external end stop is advised to prevent stress on the internal stop screw.
Outlines different operating conditions with corresponding friction coefficients, ranging from smooth operation at low speed to high accelerations with shocks and vibrations.
For semi-telescopic rails, deflection depends on the rigidity of connected structures. For telescopic rails, deflection values are provided for maximum load conditions.
Nadella telescopic rails offer options like double stroke for forward and backward extension. Various hole configurations are available, including countersunk and threaded holes.
Provides a matrix of product specifications, including installation length, extension length, and material options.
Detailed order codes are provided for different rail types and configurations, specifying installation size, rail length, and carriage details.
