The DBH 9503 oil seal is a radial shaft seal with a 36 mm shaft diameter, 52 mm housing bore and 10 mm height, in the Lx-R-AH design. It is used to retain lubricant and exclude contaminants on shafts rotating inside gearboxes, pumps and reducers. Its flexible lip runs against the shaft and its metal case fits into the housing. It is a wear part: when oil leakage appears or dirt gets in, it should be replaced with one of the same size.

This item is a DBH 9503 radial shaft seal, identified by its designation 9503. Its dimensions are 36.00 mm shaft diameter (d), 52.00 mm housing bore diameter (D) and 10.00 mm height (h). The Lx-R-AH design indicates the lip and case configuration: a single radial lip with spring and a case that is press-fitted into the housing. DBH is a brand that MR carries, so the code 9503 corresponds to that reference.

Typical applications for a seal of these dimensions are transmission shafts, centrifugal pumps, electric motors, reducers and gearboxes. In all cases it performs two functions: retaining the oil or grease inside the assembly and preventing the entry of dust, water or particles. It is also used in continuous-process equipment, where scheduled replacement prevents downtime due to leaks. If the shaft rotates with misalignment or vibration, the seal works under greater demand and its service life is shortened.

For installation, check that the shaft has no burrs or deep marks in the lip contact area. Lubricate the lip with the same oil used in the equipment before sliding it on, and use a support tube so as not to deform it. The housing must be clean and free of old sealant residue. When selecting a replacement, in addition to the 36 x 52 x 10 mm dimensions, take into account the type of fluid, the working temperature and the shaft speed. If the original design is Lx-R-AH, it is advisable to keep that configuration unless the equipment manufacturer indicates otherwise.
