n St. Petersburg, a heavy machinery manufacturer struggled with unstable equipment performance during Russia’s freezing winters, where temperatures can drop below –30°C. Conventional bearings often failed due to lubricant freezing and increased friction, leading to difficult startups and shortened service life.

We provided AV50 and AV60 precision needle bearings specifically designed for cold environments. Using anti-freeze lubricants and nickel-plated anti-corrosion treatments, the bearings maintained smooth rotation even at subzero temperatures. The precision-ground races and reinforced cages reduced wear and vibration, improving operational stability. Additionally, our custom axial-fit design improved assembly efficiency by 15%.

After six months of winter testing, the client reported 25% faster startup times, smoother machine performance, and doubled maintenance intervals. Even under severe cold, the machines maintained full output capacity. The company’s technical director commented, “The AV series bearings keep our equipment solid as rock through Russia’s winter.”

The AV50 and AV60 series are helping Russian machinery manufacturers overcome extreme cold challenges and ensure reliable operation year-round. We will continue to provide high-quality bearing solutions worldwide, enabling equipment to perform more efficiently and durably.
