The DBH 5888Pol is a radial shaft seal built around a metal body with an outer coating, sized for a 55 mm shaft, an 80 mm housing bore and a 10 mm height. Its Lx design pairs a main sealing lip with a secondary exclusion lip, which is what makes it a practical choice where dust, moisture or splashes are part of the daily environment. Gearboxes, pumps, motors and transmission equipment are the usual homes for this seal, where it keeps lubricant in and keeps contaminants out.

Reading the code helps when you are matching a replacement. The 5888Pol number identifies the item, and the three figures that follow in the sizing line describe the fit: shaft 55.00 mm, housing bore 80.00 mm, height 10.00 mm. The Lx designation tells you there are two lips on the metal carrier, one doing the sealing and one acting as an excluder. That second lip matters in dirty or damp surroundings, since it shields the bearing and the lubricant from what is floating around outside.

In service, seals of this type turn up on gearboxes, centrifugal pumps, electric motors, transmission shafts and process lines that run continuously. The job is always the same: hold oil or grease where it belongs and keep foreign matter from getting in. Because the shaft seat is 55 mm, this size fits medium equipment such as conveyors, mixers and agricultural or industrial machines.

Installation comes down to checking the fit before anything else. Confirm the shaft diameter and the housing bore against the figures above, then seat the seal with the lip toward the lubricant and, where the design permits, a thin film of compatible grease on the sealing edge. The shaft contact area should be free of burrs and heavy wear, the housing clean and undistorted, and the 10 mm height tells you how much cavity depth the seal needs.

When you send a request, the code 5888Pol or the shaft and housing dimensions are enough to get started. The designation is checked against the manufacturer's data sheet so that compatible options in dimensions and lip type can be offered, and the team can point you toward the design that best suits your lubricant and operating conditions. Quotes are handled by WhatsApp or email, and replies come back promptly.

This seal sits in the seals and oil seals line, alongside bearings, mounted units and housings, power transmission parts and lubrication and maintenance tools.
