The DBH 8490Pol oil seal is a single-lip radial shaft seal that mounts on the shaft and against the housing to retain lubricant and block the entry of dust, water or particles. Its A 075 design and its dimensions of 40.00 mm shaft, 58.00 mm housing and 11.30 mm height place it in transmission applications and rotating equipment where axial space is limited. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH radial shaft seal identified as 8490Pol, with the following dimensions: shaft diameter of 40.00 mm, housing diameter of 58.00 mm and height of 11.30 mm. The indicated design is A 075, which defines the geometry of the lip and the outer body. It is a single-lip seal, intended for rotating shafts with lubrication and to keep oil or grease inside the assembly, preventing leaks and the entry of contaminants from the outside.

Typical applications of a seal of these dimensions include gearboxes, pumps, electric motors, rollers and power transmission equipment. It is also used in agricultural machinery, conveyors and industrial equipment where there are shafts rotating inside a housing and a reliable sealing barrier is needed. The 40 x 58 x 11.30 mm size is common on shafts with a nominal diameter of 40 mm with a standard housing, which makes replacement easier when working with equipment already installed.

To mount this seal, check that the shaft and the housing are clean, free of burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and fit the seal with a tube or spacer that presses on the outer body, never on the lip. The 11.30 mm height must match the housing depth so that the seal seats fully. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.

If you need an equivalent or a close size, the most practical thing is to send us the part number 8490Pol or the current dimensions of the seal you are replacing: shaft diameter, housing diameter and height. With that data we can look for an alternative within the DBH line or other brands we carry. It also helps if you tell us the equipment where it is mounted and the working temperature, so we can fine-tune the lip material recommendation.

At MR Accesorios Industriales we carry the DBH brand and have more than 80 years of experience in the field. If you want a quote for the 8490Pol oil seal or to ask about a similar size, write to us on WhatsApp with the part number or the dimensions and we will reply shortly.
