NTN's mounted bearing units with a stainless composition are designed specifically for applications where corrosion resistance is mandatory. When subjected to environments featuring high humidity or the presence of corrosive cleaning agents, traditional cast-iron ball bearing units are more likely to degrade at a faster rate during conveyor-line-washdown cycles. To address this issue, NTN’s Stainless Steel series features full stainless steel composition, from outer housing to inner ball bearings and raceways.
The solid base construction of NTN Stainless Steel bearings offers superior mount stability and impact-load resistance than bearings with semi-solid construction do. In addition, the removal of additional cavities minimizes any space in which particle buildup can occur.
Mounted unit solutions are available in a wide array of configurations, including pillow block and two- or four-bolt flange styles. Protective endcaps can be ordered for additional protection, and are universal to all Stainless Steel series mount styles.
All stainless steel units feature grease that meets the USDA H1 food-grade specification. NTN also offers solid-grade equivalent greases for higher temperature applications.
