The DBH 8305 seal is a radial lip seal, designed to retain lubricant and exclude contaminants on rotating shafts. Due to its dimensions —57 mm shaft, 84.80 mm housing and 21 mm height— and its design A 214, it is mounted in gearboxes, pumps, electric motors and reducers where axial space is limited. At MR Accesorios Industriales we supply it as part of our line of seals and oil seals, with technical advice so you choose the right replacement.

This item is a seal from the DBH brand, identified with code 8305. Its dimensions are 57 mm shaft diameter, 84.80 mm housing diameter and 21.00 mm total height. Design A 214 corresponds to a radial shaft seal with sealing lip and metal case, suitable for rotating shafts with lubrication. It is a standard replacement part, not in-house manufacturing by MR, but an official brand that MR supplies.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, its function is twofold: to prevent oil or grease leaks to the outside and to block the entry of dust, water or particles that damage bearings. Because of its 21 mm height, it is suitable for housings with limited space on the shaft.

To install it correctly, check that the shaft diameter is within the recommended tolerance for radial shaft seals and that the housing has no burrs or wear. Lubricate the lip before installation and use an installation tool that does not damage the seal. If the shaft has play or excessive roughness, the seal may fail prematurely. Lip material selection depends on the fluid and the working temperature.

If you need an equivalent or a nearby size, the most practical thing is to send us code 8305 or the current dimensions of the seal you are replacing: shaft diameter, housing diameter and height. With that data, at MR Accesorios Industriales we look for the option available in our seal line. We can also guide you if design A 214 does not match your equipment housing.
