This SKF pillow block roller bearing unit with inch dimensions has a cast-iron housing, a two-bolt base, and TriGard seals. It is a ready-to-mount one-piece bearing housing made of ASTM International A48 grade 30 grey cast iron and is assembled, lubricated, and sealed at the factory for maximum strength and rigidity. This non-expansion-type bearing uses a pop-release locking collar for easy release from the guided shaft. The unit has TriGard seals help protect it from coarse contaminants. It is good for carrying shafts with radial or radial-and-thrust loads.

Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.

SKF manufactures bearings, seals, and lubrication systems for automotive, OEM, energy, and other and industrial applications. The company, founded in 1907, is headquartered in Gothenburg, Sweden, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance.
