The DBH 5272Sil radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its Lx design and dimensions of 25.50 mm shaft, 40.00 mm housing and 7.00 mm height make it a common replacement part in gearboxes, pumps and electric motors. At MR Accesorios Industriales we carry it as part of our seals and oil seals line.

This item is a DBH brand oil seal, identified by the code 5272Sil. Its dimensions are 25.50 mm shaft diameter, 40.00 mm housing diameter and 7.00 mm height, with an Lx design. The Lx design corresponds to a seal with a single sealing lip and an outer metal case, intended for rotating shafts with permanent lubrication. The series nomenclature makes it quick to locate the replacement part once the original code is known.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases it serves to confine the oil or grease inside the assembly and prevent contaminants from entering from outside. It is a wear part: when a lubricant leak or abnormal vibration appears, it should be inspected and replaced.

To select the correct seal, verify that the three dimensions match the shaft, the housing and the seat depth. Shaft tolerance and surface finish affect sealing: a scratched or worn shaft can prevent the lip from seating properly. During installation, lubricate the lip, avoid striking it and make sure it enters perpendicular to the housing. If the shaft is damaged, consider repairing it or using a wear sleeve.
