Industrial Gear Market Trends


The demand for more efficiency within the industrial market is driving the need for better gear design. Changes in gearboxes have led to tighter requirements on wear, seal compatibility, and filtration. Gearboxes have reduced by approximately 33% over the last forty years, resulting in higher performance requirements from the gear oil specifically in regards to foam and filtration. The desire for longer operating hours, longer maintenance cycles, and shorter downtime has created a need for gear oils that have higher cleanliness, are compatible with seals to prevent leakage, and have a longer lifespan.

What is the Purpose of Gear Oil?


Gearboxes are used in a wide array of applications and markets, and gear oil serves several critical roles to keep gears clean and running at optimum efficiency.
