Ideal for professional applications, it features a secure setscrew locking collar and effective nitrile rubber seals for optimal durability. ## Description This Hub City FB250UR series flange block has a cast iron housing with four bolt holes and a set screw locking collar. This bearing unit is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The cast iron housing is rigid and dampens vibration and its four bolt holes provide mounting stability. A collar extends from the bearing inside ring to lock the collar and bearing onto the shaft with two set screws spaced 120 degrees apart for a three-point contact hold. The steel single-row, deep groove ball bearing insert is self-aligning and accommodates misalignments between the shaft and the housing. A pressed steel cage spaces the rollers for even load distribution and prevents contact to reduce friction, vibration, and noise. Nitrile rubber seals with steel guards on both sides of the bearing protect against contaminants and retain lubricant applied at manufacture and the bearing housing has a grease fitting for reapplying lubricant. Flanged bearing units are suitable for use in industrial and commercial applications including conveyors, fans and blowers, construction machinery, and processing equipment.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.Hub City manufactures power transmission products for use in transportation, packaging, construction, material handling, and medical and food processing equipment. The company, founded in 1892, is a subdivision of Regal-Beloit and headquartered in Beloit, WI. ## Features - Four-bolt flange-style housing for a ready-to-mount installation where surface and guided shaft are perpendicular - Single-row deep groove ball bearing insert accommodates misalignments between the shaft and the housing - Cast iron housing and steel bearing unit for carrying shafts with radial or radial and thrust loads - Set screw locking collar for secure attachment to shaft - Nitrile rubber seals on both sides of the bearing keep lubricant in and contaminants out ## Images ![Hub City FB250URX1 Flange Block Mounted Bearing, 4 Bolt, Normal Duty, Relube, Setscrew Locking Collar, Narrow Inner Race, Cast Iron Housing, 1" Bore, 1.398" Length Through Bore, 2.756" Mounting Hole Spacing - Image 1](https://m.media-amazon.com/images/I/819cHMld4-L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐ Had a couple issues with the bearing falling out. ... *by B***M on Reviewed in the United States πŸ‡ΊπŸ‡Έ on June 20, 2016* Had a couple issues with the bearing falling out.
