The DBH 5463Pol is a radial shaft seal sized for a 110 mm shaft, a 140 mm housing bore and a 13.00 mm height, built in Kx design. Its job is to hold lubricant in place while keeping dust, water and other contaminants out of equipment with a rotating shaft. You will find this type of seal in pumps, gear reducers, motors and transmission cases, where the bearings and the assembly depend on a proper seal. MR supplies it as a brand.

Reading the code tells you the size: shaft 110 mm, housing bore 140 mm, height 13.00 mm. The Kx design uses a sealing lip plus a dust lip, so it retains oil or grease on one side and blocks incoming contaminants on the other. The outer diameter presses into the housing, while the lip runs against the rotating shaft. Because the lip is a wear item, it eventually hardens, loses flexibility and starts to leak.

Seals in this size range show up on equipment with larger transmission shafts: centrifugal and positive displacement pumps, speed reducers, electric motors, gearboxes, mixers and continuous process machines. Material handling equipment and production lines with shafts turning inside a lubricated housing are also common places to find them. In every case the seal does two jobs at once: it keeps lubricant where it belongs and stops particles that would shorten the life of bearings and gears.

When choosing or installing a radial shaft seal, confirm three things: the shaft diameter and housing bore match the seal, the height fits the cavity depth, and the lip design suits the lubricant and the contamination level around the equipment. Install on a clean shaft free of burrs, lubricate the lip before sliding it into place, and press on the outer ring only, using a tube or press, never on the lip. If the shaft is worn or has a deep groove, consider repairing it or using a different size.

The simplest way to get the right part is to send the dimensions of the old seal: shaft diameter, housing bore and height, along with a photo of the seal and the housing. With that information we can find an equivalent in the same brand or in another line MR carries, keeping the dimensions and design type the same. We can also tell you whether the original seal has a special feature worth preserving.
