The DBH 8508Pol radial shaft seal is a lip seal mounted between a rotating shaft and its housing to retain lubricant and stop the entry of dust, water or particles. Due to its dimensions of 50 mm shaft, 72 mm housing and 12 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment that work with oil or grease. MR Accesorios Industriales carries this brand as part of its line of seals and oil seals.

This item is a DBH 8508Pol radial shaft seal, identified by its designation 8508Pol. Its published attributes are: shaft diameter (d) 50 mm, housing diameter (D) 72 mm and height (h) 12.00 mm. The design indicated is Lx-R-H, which corresponds to a seal with a sealing lip, reinforced body and retaining spring. It is a standard replacement part within the category of radial shaft seals, intended for shafts that rotate and need lubricant containment.

Typical applications of a seal with these dimensions appear in gearboxes, speed reducers, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. In all those cases the seal performs two functions: preventing oil or grease from escaping to the outside and preventing dust, water or chips from entering the bearing or gear. It is a wear part, so it should be checked at every maintenance service.

To install a radial shaft seal, check that the shaft and housing diameters match the values on the product page, that the shaft has no burrs or marks and that the lip is oriented toward the lubricant side. It is recommended to lubricate the lip before inserting it, use a tube or socket of suitable diameter so as not to deform it, and strike only on the outer ring. If the housing is damaged or the shaft has play, the seal will not seal properly even if it is new.

If you need an equivalent or a nearby size, the most practical thing is to send us the part number 8508Pol along with the dimensions of your shaft, housing and height, and a photo of the old seal if you have it on hand. With that data we can look for an alternative within the same DBH line or from another brand we carry, always respecting the mounting dimensions. We can also guide you if the Lx-R-H design is not the one that corresponds to your equipment.

At MR Accesorios Industriales we have more than 80 years in the industrial sector and we carry DBH as an official brand. If this seal is for your maintenance, send the part number 8508Pol by WhatsApp and we will send you the quote. If you are unsure about the size, write to us anyway: with the equipment data or the original seal we can confirm whether the 8508Pol is the right one or find the size you need.
