MOUNTED MOBILITY AND VERSATILITY

Regardless of your industry type, NTN offer a diverse series of mounted bearing units to fit your application. Whether for mining, construction, or food processing, NTN has the solution for your industry.

ULTRA-CLASS™ SERIES

NTN’s flagship mounted unit line is the original solid base offering in our mounted bearing unit portfolio. It symbolizes our 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 to provide superior alignment and centering, compared to typical 90° configurations. The semi-retractable, ball-point mechanism means excellent tightening torque characteristics without damage to the shaft-mounting surface.

Protection in both wet and dry particle environments is paramount when selecting a mounted unit solution, and the Ultra-Class™ series is up to the task, allowing for usage even in food-grade environments. Using a combined elastomeric seal in tandem with NTN’s outer flinger design, each mounted unit exhibits a fan-like mechanism that keeps particles from getting near the inner ball bearing and raceways.

CORROSION-RESISTANT SERIES

The NTN Stainless Steel and Thermoplastic series of mounted units offer optimum performance for food-grade and related environments, with a strong focus on protection from oxidation, mold, bacteria, and chemical cleaning agents. Mounted-unit inserts have a stainless steel composition designed to withstand the aggressive cleaning and corrosive environments found within the food-processing industry.

The Corrosion Resistant series offers similar solid-base construction to the NTN Ultra-Class™ line, meaning excellent mount stability and impact resistance. 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 available in both Stainless Steel and Thermoplastic configurations.

Corrosion Resistant units feature USDA H1 grade grease, as well as a stainless steel bearing-unit insert composition that offers exceptional humidity resistance. NTN also offers solid-grade equivalent greases for higher temperature applications.

HEAVY-DUTY MOUNTED UNIT SERIES

NTN provides several heavy-duty mounted units designed specifically to accommodate the rigors of applications within construction, mining, and other large-scale equipment applications.

Mounted Units & Pillow Blocks

NTN’s two-part bearing housings, such as those found in the SAF series, offer a heavy-duty solution that simplifies mounting of maintenance of the units. Combined with precision-made, self-aligning roller bearings, these units offer significant benefits in terms of service life and running behavior. With a variety of sealing systems available, the two-part bearing-housing set-up provides a versatile, modular approach to mounted-unit design, offering technically and economically viable solutions for almost any application.

Where sealing is paramount in heavy-duty applications, NTN also offers a sealed-unit approach that provides even more protection than that found with the two-part series. Series such as the SPW and SFCW product lines feature a sealed spherical bearing that offers corrosion protection in these environments. The single-piece housing offers solid composition, which ensures excellent mechanical integrity and shock stability.

COMMITTED TO INNOVATION

While these product lines represent optimal solutions for an environmentally demanding industry, NTN features several other product lines that represent the collaborative design approach that NTN utilizes towards creating unique solutions for new and specialized applications.
