About SKF FSAF 518 Spherical Roller Bearing Housing, 4
This SKF spherical roller bearing housing is made of cast iron, has four mounting bolt holes, is suitable for use as a housing for spherical roller bearings in the 22200 series with a tapered bore, and provides for oil bath and circulating oil methods of lubrication. This horizontally-split roller bearing housing has a machined bearing seat for spherical roller bearing fit, four cap bolts to provide clamping force between the cap and base, dowels to locate the cap and base for ease of assembly, and a flat square foot to help accurately align the housing. It supports condition monitoring during operation by providing space to attach sensors on the top and on the side and front faces of the housing for different condition monitoring requirements. This housing is made of American Society for Testing and Materials (ASTM) A48 grade 30 grey cast iron, its dimensions are interchangeable with SAFD (ductile iron) and SAFS (cast steel) housings, the cap bolts are American National Standards Institute (ANSI) grade 8.8, and the bearing seat is machined to the G7 tolerance.Roller bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All roller bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
