The DBH 5252 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a housing. A flexible lip with a spring rides against the shaft to hold the seal while the equipment runs. You will find this size on gear reducers, pumps, motors and other transmission drives, where it protects bearings from dust and water. The 5252 code covers a 20 mm shaft, a 35 mm bore and a 10 mm width.

This seal belongs to the DBH line and carries the size code 5252. In shorthand, the dimensions are shaft 20 mm, housing 35 mm, width 10 mm. The Lx configuration means a single lip with a spring, which suits lubricated rotating shafts. DBH is one of the brands MR supplies, so the seal arrives with its factory marking and measurements.

You will typically see a seal this size in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. Its job in all of them is the same: hold the oil or grease inside and block outside particles. Machine tools, industrial washers and hydraulic systems with continuous or intermittent shaft rotation also use it.

Before installing, inspect the shaft for burrs or wear at the contact area and make sure the housing is clean and not distorted. Coat the lip with the same lubricant used in the machine, then press the seal in with a driver that contacts the outer diameter only, never the lip. Speed, temperature and the fluid being retained all affect the choice; if any of those are unclear, share your equipment details with us.

For a cross-reference, send the full original part number, the shaft, housing and width measurements, and a photo of the seal. With that we can search the same DBH line or another brand we carry. We can also tell you whether the cavity allows a different width or a design with a second lip for extra contaminant protection.
