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