NORD DRIVESYSTEMS has redefined surface protection!
Abingdon – UK: NORD DRIVESYSTEMS new NSD tupH sealed surface con-version system provides a versatile, cost effective and weight saving alternative to stainless steel gear case units for harsh environment and high hygiene drive applications. The ultra-robust finish employs a catalytic process that permanent-ly bonds a base layer to the aluminium substrate. With no application of paint or other material, aluminium gear case surfaces are transformed with a durable protective finish that has a 6- to 7-fold increase in surface hardness.
When applied to standard aluminium gear cases with suitable stainless steel hardware components, and combined with suitable sealing and lubrication sys-tems, NORD NSD tupH treated gear units can withstand the demanding envi-ronmental conditions that are encountered in washdown and chemical cleaning treatments used in the food, beverage, and pharmaceutical industries.
Extensive tests show that NSD tupH surfaces sustained no damage after a full year of salt water rinsing, which included the use of aggressive cleaning chemi-cals and high-pressure cleaners. Salt spray tests showed no corrosion after 1,000 hours. The NSD tupH surfaces also proved superior compared with standard systems during chip resistance testing: all gear units featuring protec-tive coatings or varnishes, even nickel, or nickel/teflon combinations, are sus-ceptible to peel off and scratching due to general wear and tear but NSD tupH gear unit surfaces are scratch-proof, very resistant to impacts and do not cor-rode.
Unlike stainless steel models, which most manufacturers provide for only a few drive types, the NSD tupH treatment is available for a very wide range of products – users can choose from virtually all aluminium gear units. The weight factor is another advantage: since aluminium as a basic material is considerably lighter than steel, this solution has substantially less mass and thus provides better installation options for mobile machinery and other weight sensitive applications. Moreover, NSD tupH drive units are also cheaper than stainless steel systems thanks to their choice of basic material.
NSD TupH, a breakthrough in protection at a molecular level.
As a leader in the power transmission industry, NORD Gear is committed to providing value to industries where end users demand durable equipment to withstand a variety of harsh environments. The market has long awaited a product with such a large range of standard reducers with the corrosive resistance properties of a stainless steel product without the excessive cost.
Surface Comparison
On an original painted aluminium surface the paint simply lies on top of the aluminium substrate and may even bridge across pores in the metal. Since paint does not form a permanent bond to the substrate, it can easily release at very low stress levels.
The NSD TupH process includes a base layer that is permanently bonded to the aluminium substrate and provides a powerful foundation for adhesion of the surface sealant. This foundation provides excellent roughness, is 6-7x harder than the aluminium substrate and up to 1000x harder than paint.
