Understanding Gear Failures and Limitations of Standard Lubricants

Under challenging operating conditions, issues like microcracks, micropitting, sharp edges, or pitting (material breakouts) can occur—leading to gear failure and production downtime.

Prolonging Gear Life with Anti-Micropitting Gear Oils

Anti-micropitting gear oils allow previously damaged gears to continue functioning—sometimes for several years—until a replacement is available. These oils have been developed through collaboration with gearbox manufacturers and research institutes, offering benefits like increased lifespan, improved safety, and cost savings.

Technology Behind High-Performance Gear Oils

New formulations, such as the Eutectic Formula, ensure optimal performance even under extreme loads and temperatures. These oils provide maximum wear protection, even under the toughest conditions like wind power generation.

What Causes Micropitting?

Factors such as oil film thickness, temperature, and slide-to-roll ratio contribute to micropitting. This wear appears as a dull, gray finish, caused by surface fatigue. It alters the gear tooth profile, creating noise, vibration, and misalignment.

Combating Oil Aging in Industrial Gearboxes

Oil aging accelerates with temperature—doubling with every 10°C rise. Anti-micropitting gear oils help reduce oil temperature and aging by using advanced additives with low friction coefficients.
