3-bolt flange brackets are flange housing units with all 3 bolt holes located on one side of the bearing. These flange units specialize in applications where mounting space is restricted, but are still suitable for rigorous conditions and industries such as agricultural, conveyors, and construction equipment.Normally these bearings
can be adjusted or aligned within the housing to accommodate long shafts. Most manufacturers produce flange units in two series: inch dimensions and metric dimensions. Materials include cast iron, thermoplastic, glass filled PBT polyester, stainless steel, and other metals.Plastic housing units avoid rust and corrosion, requiring minimal to no maintenance, however they may not be suitable in high temperature applications.Common flange unit features include a grease fitting for adding lubricant, or slingers on the sides for dust protection. These units are either set screw locking type, sleeve collar, or eccentric locking collar locking type for one directional applications. A multitude of bearing inserts with varied materials and seal types are available with these housing units. Chrome steel bearings are regreaseable and often paired with cast iron units. UHMW-PE bearings are designed for applications in wet or harsh environments, are self-lubricating, and can be used with most metal housings. Bronze bearings
are preferred for lighter applications and continuous lubrication. Stainless steel, nickel, and plated zinc are also available, depending on the manufacturer.

are more suitable for light duty applications. Find the bearing that suits your application at MRO Supply; Our formidable selection of 3-bolt flange brackets from various brands, sizes, materials, and bearing types offers variation and customization to suit any application.
