A square, four-bolt flange bearing from the LINK-BELT FCEU 300 series mounts flat against a machine frame and carries a rotating shaft, mainly under radial load. Conveyors, agitators and drive packages use this style of unit because it bolts down easily and can be lined up without extra supports. MR Industrial Accessories supplies it to maintenance and purchasing teams.

Read the code in two parts. FCEU is the LINK-BELT four-bolt flange family, and the digits that follow give the shaft size. Across the 300 series the number climbs with the diameter, so a larger figure means a bigger shaft and a wider bolt-hole spacing. The suffix never changes how the unit mounts, only its size. Send the complete part number, or simply the shaft diameter, and we will confirm the reference you need.

Typical duty covers belt and chain conveyors, mixers, pumps, fans and process lines where the shaft runs horizontally or vertically on sheet metal or cast iron. Food plants, cement and aggregate operations, and wastewater treatment sites favor the square flange because it sits on a flat surface with no extra machining. Material handling equipment and agricultural machinery also use it where a unit has to be swapped out quickly.

Selection depends on radial and axial load, running speed and the surroundings. Dust, water or regular washdowns call for a unit with heavier sealing. The mounting face has to be clean and flat, and the four bolts should be drawn down evenly so the flange does not distort. Relubricate on the duty cycle, and keep the shaft aligned with the flange to avoid stressing the bearing. If vibration or heat shows up, inspect the fit and the grease first.

Flange bearings from several brands share standardized dimensions, but they do not always swap directly. Shaft diameter and hole spacing can line up while flange diameter, seal design and shaft locking differ. Compare the full part number and the key dimensions before pulling a unit. Send us the original reference and we will point out the compatible option.

For an FCEU flange bearing, message the part number or shaft diameter to MR Industrial Accessories. We will quote the matching LINK-BELT reference, and if you need a variant that is not listed, send the model and we will get back to you. We can also walk you through installation and lubrication.
