## Overview

The FB250DRWX1 Flange Block Mounted Bearing is designed for robust performance with a four-bolt flange housing, accommodating misalignments, and featuring a durable ductile iron construction. Its secure set screw locking collar and effective nitrile rubber seals ensure longevity and reliability in various applications.

## Description

This Hub City FB250DRW series flange block has a ductile 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 ductile iron housing is rigid and fatigue resistant 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.

I bought four of these to build a double swing driveway gate.  The movement is very smooth.  I estimate each gate weighs 600 pounds.
