Gearing up for lubrication

Paul Boughton

The Lubricants and Fuel Additives Platform of water, energy and maintenance solutions provider NCH Europe has launched Top Blend, a new multi-viscosity and multi-purpose gear oil.

Designed for virtually all types of enclosed gear systems, Top Blend is available in several grades including types 80W-90 and 85W-140, meeting the requirements for grades ranging from 80W-140W. Target applications include industrial, food and beverage, packaging, processing and automotive.

With proper maintenance and when used in combination with NCH's Flush and Clean product to perform a flushing procedure before changing, Top Blend lasts up to four times longer than ordinary gear oils. This means it carries on working for up to 320,000km in automotive gear boxes or around 8,000 hours in stationary equipment.

Top Blend stands out with a unique formula that incorporates adhesive polymers, tackifiers, anti-foam, anti-corrosive and anti-friction agents, emulsifiers, detergents, pour depressants, shock-load reducers and leak inhibitors.

This powerful combination significantly improves component life, reducing downtime, labour costs and the frequency of parts replacement. Providing a high thermal stability, Top Blend ensures fewer oil changes and improves seal quality, which results in less oil needing to be replaced due to leaks.

"We know that up to 70% of mechanical gear-wear occurs on startup," explained Mark Burnett, VP of the Lubricants and Fuel Additives Innovation Platform at NCH Europe. "Dry starts are responsible for wear such as cold-weld fusion, pitting, and metal-particle contamination that can cause foaming, oxidation and the buildup of acidic compounds and sludge.

"Top Blend adds a protective film to rubber seals, which both conditions and reduces the chance of cracking and shrinking, traditionally a major cause of leakages. This same film coats the gears, ensuring good viscosity at startup that prevents mechanical wear.

"Customers testing Top Blend have told us that the way the blend of oxidation inhibitors and dispersants reduces heat stress, foaming based acidic compounds and sludge caused by oxidation particles is adding real value to their business in terms of tangible savings."

Subjected to stringent testing routines during development, Top Blend meets or exceeds leading industry standards including API, AGMA, SAE, US Milspec, and numerous automobile, truck and original equipment manufacturer (OEM) standards.
