Part number 1027 belongs to the DBH line of radial shaft seals. It is a lip seal: the outer body sits in the housing bore while the lip rides on the turning shaft, holding lubricant inside and keeping dust, water and particles out. The nominal size is 57.15 mm shaft, 81 mm housing and 12.70 mm height, in the Mx design. MR Industrial Accessories supplies this brand within its seal and oil seal range.

Reading the code is straightforward. The 1027 identifies the item in the DBH catalog, and the three figures that follow in any listing are always shaft, housing and height. In this case 57.15 mm, 81 mm and 12.70 mm. The Mx designation covers the profile of the lip and the shape of the metal case, made for a standard housing bore. Because it is a dynamic seal rather than a static O-ring, it is expected to work continuously against a rotating surface.

Sizes like this turn up in gearboxes, centrifugal pumps, electric motors, conveyor rollers, fan shafts, mixers and machine tools, anywhere oil or grease is present and the surroundings are dirty. The seal does two jobs at the same time: it keeps lubricant from escaping and it slows contaminants on their way to the bearings. Vibration or misalignment puts extra stress on the lip and shortens how long it lasts.

Before ordering, confirm all three dimensions against the shaft, the housing bore and the cavity depth. Look at the shaft surface as well: scoring, wear or a burr will destroy a new lip quickly. The bore needs to be clean and free of dents, with the entry chamfer intact. Coat the lip with the same oil or grease used in the equipment, set the seal square to the bore and press it in with a tube or arbor press that contacts the outer ring only, never the lip. A worn shaft may call for a repair sleeve first.

For an equivalent, send part number 1027 plus the shaft, housing and height figures from the nameplate or drawing. A photo of the old seal beside a caliper works too. We check those numbers against the catalog and come back with options that fit the same cavity, from the same brand or another line. If Mx is not the right design for your equipment, we will say so before quoting.

Quotes are handled by WhatsApp or email. Send the part number and the quantity you need, and if the machine is down include the shaft and housing dimensions so we can rule out variants.
