Product range
NORTHON offers a comprehensive selection of high-performance couplings, designed to meet the demands of various industrial applications. Whether ensuring precision in high-speed machinery or absorbing misalignments in heavyduty systems, our couplings guarantee efficiency, durability, and reliability. The Quality Control Department ensures rigorous inspection at every stage, from raw material selection to final product verification. Upon request, certifications for materials, heat treatments, and dimensional accuracy are provided.
Gear Couplings – Series Z
Built to withstand high torque and extreme working conditions, these couplings effectively compensate for angular and parallel misalignments, ensuring smooth and secure power transmission. Thanks to their forged and heat-treated alloy steel construction, they deliver exceptional performance even in the most demanding environments. Their crowned tooth design allows greater flexibility, while integrated grease fittings facilitate easy maintenance.
Elastic Couplings – Series PN & PNHP
Designed to absorb torsional shocks and vibrations, these couplings provide excellent misalignment compensation while preserving the integrity of connected machinery. The PN series, crafted from C40 UNI 7845 steel and anti-oil synthetic rubber elements, is ideal for general industrial applications.
For higher torque demands, the PNHP version features reinforced alloy steel components and high-resistance elastomers, ensuring enhanced durability and performance.
Elastic Star Couplings – Series PSA
Compact yet powerful, the PSA series is the optimal choice when space constraints are a concern. With its polyurethane star element, available in different hardness levels, it maintains high torque transmission capacity while offering excellent resistance to temperature variations. This makes it particularly suitable for applications requiring precision and efficiency in limited spaces.
Elastic Pin Couplings – Series Revolution
For applications requiring lightweight yet high-torque solutions, the Revolution series provides superior alignment flexibility and easy maintenance. Constructed from aluminum alloy, these couplings offer resistance to corrosion and oxidation, making them ideal for demanding industrial environments.
Additionally, the design allows for quick replacement of elastic elements without dismantling connected machinery, reducing downtime and maintenance efforts.
Flexible Disc Couplings – Series FLX
When torsional rigidity and zero backlash are essential, NORTHON’s FLX series offers an advanced solution. These couplings are self-lubricating and maintenance-free, with stainless steel lamella packs that provide superior durability. Designed to perform in extreme temperature conditions (-30°C to +240°C), they are ideal for applications with frequent start-stop cycles, high-speed rotations, and precise motion control requirements.
