LINK-BELT 300 series flange units are four-bolt flange bearing units used to support rotating shafts on walls, frames and metal structures. They suit power transmission drives that need a firm mounting point and straightforward alignment. MR Industrial Accessories LLC supplies this line to industrial plants, workshops and maintenance teams across the United States and in several Latin American countries.
Reading a 300 series part number is simple once you know the blocks. The letters FEU mark a flange unit with a mounted bearing. The number that follows tells you how many mounting holes the flange has. The last digits identify the bearing size and shaft diameter, so FEU3K27 and FEU3K31 share the same flange layout but take different shaft sizes. The K suffix shows how the bearing grips the shaft, which in this series is by set screws. With that structure in mind, you can order the exact unit you need.
These units appear in belt conveyors, bucket elevators, mixers, agitators, blowers and process lines in the food, chemical, cement and aggregate industries. They are common in milling plants, balanced feed plants and material handling systems where a shaft has to be supported on a flat surface at four anchor points. The four-bolt flange spreads the load and lets you mount the unit on a wall or frame without machining a housing.
Selection comes down to shaft diameter, the radial and axial loads the unit will carry, and the working environment. Sealing matters most in dusty or damp areas, where extra protection is worth considering. The bearing arrives pre-lubricated from the factory, but severe applications call for a relubrication plan. When mounting, make sure the flange seats without distortion and tighten the four bolts evenly, since uneven tightening can cause misalignment and shorten bearing life.
LINK-BELT 300 series flange units interchange with equivalent units from other brands that follow the same mounting standard and flange dimensions. That compatibility simplifies replacement in existing equipment without touching the structure. To replace a unit, send the original part number or the shaft dimensions and hole spacing. MR Industrial Accessories LLC will identify a compatible alternative or quote the part if it is a special item.
To request a quote for a LINK-BELT 300 series flange unit, send the part number by WhatsApp or email.

Frequently asked questions
- What does the designation FEU3K27 mean?
- FEU indicates a flange unit with mounted bearing, the 3 is the number of mounting holes, K is the shaft mounting system and 27 identifies the bearing size and shaft diameter. Every part number in the series follows this logic.
- Can it be replaced with another brand?
- Yes, if the replacement matches the flange dimensions and shaft diameter. The 300 series is a mounting standard, so many brands offer equivalents. Send the original part number and MR will tell you the compatible alternative.
- How are these units lubricated?
- The bearing comes pre-lubricated from the factory. In applications with dust, humidity or high temperatures, relubrication according to the maintenance plan is advisable. Use a grease compatible with the seal and avoid mixing different bases. MR can advise if you need help.
