When a rotating shaft passes through a housing, the DBH 6776 radial shaft seal keeps grease or oil where it belongs and keeps dust and moisture out. Its size — shaft 34.93 mm, housing 72.00 mm, height 7.90 mm — together with the A 156 design, fits equipment where the seal sits in a narrow axial space. MR supplies this brand and helps you match the right seal to the job.

The reference 6776 identifies this lip seal within the DBH line. Reading the size is straightforward: d is the shaft it runs on, D is the bore it presses into, and h is how deep it sits. Here that means 34.93 mm on the shaft, 72.00 mm in the housing and 7.90 mm of height. The A 156 designation describes how the lip and the metal case are shaped, so the sealing edge holds lubricant inside a cavity while the shaft turns. It is a standard replacement item among the seals and oil seals MR carries.

Seals in this size range turn up in gearboxes and reducers, centrifugal pumps, electric motors and other power transmission drives. Wherever a shaft leaves a housing, the seal closes that gap: it keeps the lubricant in and shields the bearings from dust, water and process particles. Agricultural machinery and process equipment are common places to find one as well, since they call for a closure that works reliably with little attention.

Before fitting a new seal, confirm that the shaft and housing measure what the part number calls for, and check that the shaft surface is clean, with no burrs or score marks. Lubricate the lip first, then seat the seal squarely on the shaft; forcing or striking it can distort the case. If the equipment runs at high peripheral speed or elevated temperature, check with MR whether the A 156 design suits those conditions.

Looking for an equivalent? Send the code 6776, or simply the shaft, housing and height measurements, and we can search within the same category or across the other brands we supply. A photo of the old part and the housing also helps avoid mix-ups. The aim is a correct match the first time, with no back and forth.
