This LINK-BELT 3-bolt flange bracket is a mounted assembly that pairs a cast iron housing with a self-aligning insert bearing. It supports rotating shafts where a three-point front mount is needed, as in conveyors, mixers, fans and process equipment. MR Industrial Accessories LLC supplies this line and assists with selecting the correct part number based on shaft diameter and locking style.

Reading the part number is straightforward. The first letter shows the housing family, the next digit gives the number of mounting bolts, the following letter identifies the housing type, the M means the shaft diameter is in millimeters, and the E denotes the insert type. So P3S2M20E is a 3-bolt flange bracket for a 20 mm shaft, while P3S2M40E is for a 40 mm shaft. The full code points to one specific part.

These brackets are common in food and beverage plants, material handling, chemical processing and process equipment assembly. The 3-bolt flange mounts to sheet metal or structure with a fixed orientation, which helps when the shaft is horizontal and access is tight.

When choosing, consider shaft diameter, load type and the operating environment. The insert typically comes with contact or labyrinth sealing, and a tighter seal is better in dusty or wet conditions. Insert lubrication is usually permanent, but at high temperatures or speeds the grease type should be checked. Aligning the flange with the shaft prevents stress on the bearing.

Equivalents exist from other brands under their own naming systems. Interchangeability depends on flange dimensions, shaft diameter and insert locking type. A similar part number is not enough; drawings must be compared. For a replacement, send the original part number and we will identify the compatible alternative.
