The DBH 6446 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —54 mm shaft, 91.38 mm housing and 12 mm height— make it suitable for equipment with standard housings. The Ls design indicates a single-lip configuration, suitable for applications requiring low friction and good sealing. MR Accesorios Industriales carries this brand and advises you so you choose the correct seal for your equipment.

This item is a radial shaft seal from the DBH brand, identified with part number 6446. Its dimensions are 54 mm shaft diameter, 91.38 mm housing diameter and 12.00 mm height. The Ls design corresponds to a single sealing lip, without an additional dust lip, intended for applications where the seal sits in a machined cavity and the shaft rotates in contact with the lip. It is a standard replacement part for equipment requiring oil or grease containment and protection against dust and dirt.

Radial shaft seals such as the DBH 6446 are used in gearboxes, pumps, electric motors, transmission shafts and industrial equipment in general. Their main function is to prevent lubricant leaks and the entry of external particles that accelerate wear of bearings and gears. As it is a critical component with a relatively low cost, it is advisable to replace it every time the equipment is disassembled, especially if leaks or hardening of the lip are observed.

To correctly install this seal, verify that the shaft has no burrs or excessive wear in the contact area. Lubricate the lip with the same grease or oil used in the equipment before inserting it into the housing. Installation must be done with uniform pressure on the outer face, using a tube or socket that rests on the outer diameter, never on the lip. If the housing has a chamfer, make sure the seal enters perpendicular to the shaft to avoid deformation.

If you need an equivalent size or a close variant, you can send us part number 6446 or the dimensions of your current seal (shaft diameter, housing and height). At MR Accesorios Industriales we have alternatives from other brands and can guide you according to the application. We can also help you identify the appropriate design (Ls, double lip, with dust lip) according to the working conditions of your equipment.
