Part number 6755 is a DBH radial shaft seal, also called a lip seal. It keeps lubricant inside the assembly and keeps dust, water and other particles out along a rotating shaft. The size reads as follows: shaft 50.80 mm, housing 57.95 mm, height 11.50 mm, with an A 033 construction. Gearboxes, pumps, motors and similar industrial equipment with tight mounting space are the usual homes for this seal. MR Industrial Accessories supplies the DBH line and can help you confirm the right choice.

How the code reads: 6755 is the DBH reference for this seal, and A 033 describes how the seal is built, which covers the lip style and the material used. The three figures that matter for fit are the shaft diameter of 50.80 mm, the housing bore of 57.95 mm and the 11.50 mm height. Once the seal sits in the bore, its lip rides on the shaft and forms the barrier that holds grease or oil in and contamination out.

Where it is used: reducers, gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each of these, the seal shields the bearings and internal parts from losing lubricant or taking in abrasive matter, which helps the assembly reach its expected service life. You will find seals of this type in process machinery, plant equipment and vehicles, wherever a clean, leak-free joint matters.

Fitting it correctly: clean the shaft and the housing bore and check both for burrs, scratches or rust before you start. Coat the lip with the same oil or grease the seal will retain, then press it in with a proper installation tool so the lip is not cut or rolled. When selecting a seal, look at shaft speed, working temperature and whether the elastomer tolerates the fluid in contact. If any of these points is unclear, ask us and we will review the application with you.

Finding an alternative: send us reference 6755 or simply the measured shaft and housing dimensions. From that we can search other brands and series that do the same job, and we can also explain the A 033 configuration and the options around it. The 6755 number belongs to DBH, so a matching replacement will normally carry a different reference even when the dimensions line up.

Quoting: message us on WhatsApp with the part number or your dimensions. MR Industrial Accessories answers with technical input and helps you settle on the right seal for the equipment.
