When a rotating shaft needs to hold lubricant in and keep grit out, a radial lip seal like the DBH 6050 is the usual answer. This seal is built around a 69.85 mm shaft, a 126.95 mm housing bore and an 11.90 mm overall height, so it fits assemblies where axial room is tight. Its Mz configuration pairs a primary sealing lip with a second lip that works as a dust excluder. DBH is one of the brands MR supplies for both repair jobs and new builds.

The designation 6050 identifies this radial shaft seal, and the three figures that matter when you pull one off a machine are shaft 69.85 mm, housing 126.95 mm, width 11.90 mm. The Mz layout uses a metal case with an outer coating, a main lip that rides the shaft and a secondary lip positioned to block external particles. That combination suits rotating shafts where oil or grease has to stay inside the cavity while dust, chips or washdown spray stay outside.

Sizing shows up across gearboxes, pumps, speed reducers, line shafts and process equipment that runs continuously. Plants handling food, paper or water often see fine dust or splashing, and there the excluder lip earns its place by keeping the lubricant cavity clean. The same seal is a common fix on older machinery: a worn unit comes out, a new one with matching dimensions goes in, and the housing stays untouched.

Before ordering, confirm the shaft and bore measurements against the values above, and check that the 11.90 mm height sits properly in the cavity without standing proud or leaving a gap. The Mz profile calls for a smooth shaft finish with no splines or keyways running through the lip path. Coat the lip with the same oil or grease used in the equipment, press the seal in square to the shaft, and seat it with even pressure rather than sharp blows. A grooved shaft may need a repair sleeve or a different size.

If you are chasing an equivalent, the fastest route is to send the code 6050 along with the dimensions you measured: shaft, housing and height. From there we can check alternatives in the DBH line or among the other brands we carry. Tell us too if the bore has a recess or if axial space is limited, and we can point you to a profile that drops in without machining.
