The DBH 1370 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and stop the entry of dust, water or particles. With 33 mm shaft, 44 mm housing and 8 mm height, and Mt design, it is used in gearboxes, pumps, electric motors and power transmission equipment.

This item is a DBH 1370 radial shaft seal, identified by its designation 1370. Its dimensions are 33 mm shaft diameter, 44 mm housing diameter and 8.00 mm height. The Mt design corresponds to the construction variant of the lip and metal body, intended for rigid housings and shafts with continuous rotation. The lip elastomer works on the shaft with slight interference, while the outer diameter maintains the fit in the housing. It is a wear part: when the lip hardens or becomes marked, it begins to lose oil.

Typical applications for a seal of this size appear in gearboxes and gearmotors, centrifugal pumps, electric motors, rollers and transmission equipment. It is also found in machine tools, mixers and conveyors, where there is a shaft rotating inside a lubricated housing. In all those cases it performs two functions at once: it prevents oil or grease from escaping and blocks the passage of contaminants toward bearings and gears. For this reason it is advisable to inspect it every time the equipment is disassembled.

To mount it, clean the housing and shaft, verify that there are no burrs or tool marks and lubricate the lip with the same grease or oil used in the equipment. Insert the seal perpendicular, without striking the lip, using a tube or shim that rests on the outer diameter. When choosing a replacement, compare the three dimensions —shaft, housing and height— and the type of design; if the shaft is worn, evaluate a sleeve or a seal with the lip in another position. A seal with correct dimensions but poorly mounted will leak just the same.

If you need an equivalent or a nearby size, send us code 1370 along with the shaft, housing and height dimensions, and a photo of the old part if you have one. With that data we search the DBH line and the available alternatives for the option that best fits your equipment. We can also advise you if the housing has a shoulder, if the shaft shows wear or if you need a variant with a material resistant to higher temperatures.
