Hub City FB250URX1-1 4S Flange Mounted Bearing

Hub City FB250URX1-1 4S flange mounted bearing is a flange-mounted bearing unit from Hub City designed to support a rotating shaft with a fixed mounting flange. Flange-mounted bearings secure to a frame or base via bolts in the mounting flange, providing alignment stability and a straightforward installation path in equipment where space constraints or mounting surfaces dictate a surface-mounted solution. This model specifies a 1-1/4 in bore, defining the shaft diameter it is designed to accommodate, and is identified by the part number FB250URX1-1 with catalog reference #328977. The '4S' designation in the name denotes the configuration within the FB250URX1-1 family, assisting purchasers in differentiating this variant during sourcing. The bore size and flange mounting together determine mounting interfaces and shaft fit for this specific bearing, helping buyers verify compatibility with their mechanical drawings before purchasing. For proper selection, verify the model against your shaft size—1-1/4 in bore—and the mounting pattern specified by your design drawings.
