SKF has launched a newly re-engineered product line of mounted ball bearing units with industry-standard inch series cast iron housings in several designs, high-performance SKF inch or metric insert bearings, and several shaft-locking methods. These mounted bearing units will suit a wide range of light- and medium-duty industrial applications, including conveyor systems, fans and air-handling equipment, and similar machinery across industries.

Four robust cast iron housing types have been introduced: pillow block units (P2B, P2BL, and P2BM series), 4-bolt square flange units (F4B and F4BM series), 2-bolt oval flange units (F2B series), and tapped base units (P2BT series). All housings conform to ABMA (American Bearing Manufacturers Association) inch series dimensional standards and their solid construction adds strength and promotes stability in service. The housings in an assortment of bore sizes are supplied pre-lubricated and with grease fittings for re-lubrication. Housings easily slip fit onto a shaft. Set screw, eccentric, or concentric shaft-locking mechanisms can be specified.

Unlike competing versions in the marketplace, these mounted units exclusively integrate highly engineered, high-quality SKF brand insert ball bearings (inch or metric). Their raceways have been ground and honed to provide precision, quiet running, and higher speed capability. A molded glass fiber reinforced polyamide cage adds durability. In addition, the outside diameter of the bearing and the inside diameter of the housing have been uniquely sphered, allowing the bearing to swivel within the housing and compensate for any errors in initial alignment during installation.

These mounted ball bearing units ultimately offer ideal solutions accommodating diverse mounting surfaces, load requirements, shaft sizes, and dimensional requirements, whether in OEM or aftermarket applications. Custom mounted bearing products can be developed.
