At MR Accesorios Industriales we sell it and advise you so you choose the right seal for your application.

This item is a DBH brand radial shaft seal, identified by part number 5281. Its dimensions are 70.00 mm shaft diameter (d), 90.00 mm housing diameter (D) and 10.00 mm height (h). The Lz design corresponds to a seal with a sealing lip and a specific construction that defines its behavior in service. It is made of elastomer with a metal case that gives it rigidity for press fitting into the housing.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all cases, the function is twofold: retain the oil or grease inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and gears. It is a critical part in industrial maintenance, because its failure causes lubricant loss and greater damage.

To correctly install this seal, verify that the shaft has the proper hardness and surface finish, and that the housing is clean and free of burrs. Lubricate the lip before inserting it and use an installation tool that presses on the outer face, never on the lip. Seal selection must consider rotation speed, working temperature and the type of lubricant. If you have doubts, consult us with your equipment data.
