## Overview

The Spyraflo PB4-1250-B SAE-840 Oil Impregnated Bronze Bearing Pillow Block features a robust two-bolt housing and a sintered aluminum design, ensuring high strength and corrosion resistance.

## Description

This Spyraflo pillow block bearing has an aluminum housing and an oil-impregnated bronze bearing insert with a 1.250-inch bore diameter. It is suitable for supporting shafts that carry radial loads, such as in material handling. The one-piece sintered aluminum bearing housing is lightweight and corrosion resistant, has a flat square foot to help accurately align the housing, and has two bolt holes. The Society of American Engineers SAE-840 bronze sleeve bearing insert is oil impregnated, containing 25 percent oil volume within the porous structure of the insert to provide a film of lubricant between the bearing and shaft and help ensure long life. This bearing allows self-realignment of up to 5 degrees and compensates for static and dynamic alignment errors, it has an operating temperature range of -20 to 200 degrees F, and it is permanently sealed and lubricated to help extend service life. This sleeve bearing pillow block is suitable for use in material handling applications, such as conveyors.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.Spyraflo manufactures bearings and bearing accessories. The company, founded in 1961 and headquartered in Peachtree City, GA, meets International Organization for Standardization (ISO) standard 9001:2008.
