NTN Unveils ROX to American Markets

Schaumburg, Ill. — NTN Bearing Corporation of America (NBCA) is pleased to announce the launch of the ROX spherical roller bearing product line to the American markets. This product line is specifically designed to withstand the extreme conditions of aggregate, mining, and heavy industrial environments.

ROX is a unique solution designed using NTN’s expertise in the aggregate and mining industries. It is the only spherical roller bearing on the market with double metal shields affixed to the cage. This patented technology durably protects the inside of the bearing from external contamination while improving grease retention.

“We are thrilled to be able to offer our customers the newest of our cutting-edge solutions,” said Kris Leming, Product Manager, NBCA. “Combining robustness, ease of use, and proven performance, ROX sets a new standard for reliability in heavily contaminated industrial environments. This new solution completes one of the most extensive ranges on the market and confirms NTN’s commitment to providing sustainable, high-performance solutions adapted to the realities of the field.”

Perfectly interchangeable with standard open bearings of the same size, ROX is designed to operate in particularly demanding environments: abrasive dust, mud, vibration, shock, and wide temperature variations (-40°F to +400°F). The metal shields effectively block the entry of dust and debris, and nitriding the shields considerably improves resistance to impacts, which are very prevalent in aggregate and mining. The absence of contact with the outer ring ensures zero friction and allows for misalignment of up to 2°, as well as play control.

Tests carried out on the product have shown a twofold increase in minimum service life when compared to standard solutions. With optimized grease retention, ROX also reduces re-lubrication frequency by more than 50%. ROX reduces maintenance, decreases unplanned downtime, and improves productivity.

Key benefits summary:

• 100% interchangeable with premium standard (ISO) bearings
• Doubles minimum service life
• Reduces re-lubrication frequency by more than 50%
