A 4-bolt flange bearing from the LINK-BELT 3200 series fastens a rotating shaft to a flat surface such as a wall, frame or steel structure. It suits equipment where the bearing has to be flanged and lined up with the shaft, and its sealing keeps lubricant in while keeping dust out. MR Industrial Accessories supplies this line to plants and workshops across the United States and Latin America.

Reading the code tells you what you are holding. Take 3210FT1, 3210FT3, 3211FT1 and 3211FT3: the leading digits 3210 and 3211 identify the series and size, meaning 3200 series bearings built for different shaft diameters. FT marks the 4-bolt flange version. The trailing digit separates sealing or configuration variants, so FT1 and FT3 should not be swapped without first checking the mounting.

You will find these units on belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and other process equipment. Food, chemical, cement and metallurgical plants rely on the flange design because it lets the bearing bolt straight to sheet metal or structural steel, with no machined housing required. Older machines are another common case, where an original bearing is replaced without touching the bedplate.

Shaft diameter, load type (radial, axial or combined) and the surrounding environment drive the selection. Sealing deserves close attention: dusty or damp locations call for a reinforced seal variant. At installation, check that the flange lies flat and that all four holes line up, since a twisted flange introduces stress and shortens bearing life. Use the lubricant specified for the working temperature and control internal clearance according to the fit.

LINK-BELT 3200 series bearings are often interchanged with equivalent lines from other manufacturers that share the same flange designation and size. Shaft diameter, hole spacing and sealing type are the points to compare. A bearing of equivalent performance can serve as a replacement as long as the mounting dimensions match, and MR Industrial Accessories can point you to the compatible option.
