When a rotating shaft needs its lubricant kept in and outside contamination kept out, a radial shaft seal does the job. The DBH 1150 is one of those seals, built to the Mz design and sized at 122.20 mm for the shaft, 152.40 mm for the housing bore and 7.14 mm in height. MR Industrial Accessories supplies this brand within its seals line and can help you verify the dimensions before you request a quote.

Reading the code is straightforward: the DBH line identifies the seal family, and 1150 points to this particular size. The three figures that matter are d, the shaft diameter at 122.20 mm; D, the housing bore at 152.40 mm; and h, the overall height at 7.14 mm. In the Mz design, a single lip with a spring works against the shaft to hold oil or grease in place, while the metal case is pressed into the machined cavity.

Seals in this diameter range show up in gearboxes, centrifugal pumps, mixers, conveyors and power transmission equipment. Whatever the machine, the task is the same: keep lubricant from migrating outward and keep dust, water and other contaminants from working their way in, where they would speed up wear on bearings and gears. That is why this seal is a common item on industrial maintenance lists.

Before fitting a replacement, inspect the shaft for burrs or deep marks in the contact zone and make sure the housing is clean and undistorted. Apply lubricant to the lip, then seat the seal with a support tube that pushes on the metal case rather than the lip. If the shaft already shows wear, an offset-lip design may be worth considering so the same failure does not return.

To source an equivalent, send the code 1150 together with the shaft, housing and height dimensions and the fluid being retained. A photo of the old part or the housing drawing also helps. With that information, the team reviews options in the same radial shaft seal category and confirms which one fits.

MR Industrial Accessories carries DBH among the brands in its seals and oil seals range. For equipment that is running, message the code 1150 and the dimensions on WhatsApp or by email, and the team will reply promptly with a quote and the alternative that suits your application.
