Providing the durability and flexibility required for food-grade environments.
STAINLESS STEEL SERIES
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.
The NTN Thermoplastic series offers comparable performance to our Stainless Steel series, but with added focus on protection from mold, bacteria, and chemical cleaning agents. Housings feature a white PBT composition that is designed with smooth surfacing to prevent particle buildup and retention.
The Thermoplastic series offers similar solid-base construction to the Stainless Steel series, meaning excellent mount stability and impact resistance. With pillow block, flange, and endcap availability similar to those featured in the Stainless Steel series, the Thermoplastic series provides you optimum flexibility when selecting the appropriate bearing unit for your application.
Thermoplastic units also feature USDA H1 grade grease, as well as a stainless-steel bearing unit insert composition that offers exceptional humidity resistance.
NTN’s flagship, mounted-unit line provides an excellent offering for food processing applications that don’t require assembly line washdown. The Ultra-Class line is the original solid-base offering in our mounted bearing unit portfolio and has come to symbolize NTN’s commitment to performance and reliability.
Featuring NTN’s exclusive ball-point, set-screw design, the Ultra-Class black-oxide-plated insert provides 120° screw orientation, meaning superior alignment and centering when compared to typical 90° configurations. The semi-retractable, ball-point mechanism enables excellent tightening torque characteristics without damaging the shaft-mounting surface.
Protection from particles in pharmaceutical or dry-good environments is paramount when selecting a mounted unit solution, and the Ultra-Class series is up to the task. Using a combined elastomeric seal, in tandem with NTN’s outer flinger design, each mounted unit exhibits a fan-like mechanism that effectively keeps particles away from the inner ball bearing and raceways.
