The DBH 8717Pol is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It has a 31 mm shaft diameter, a 50 mm housing diameter and an 8.00 mm height, with an Lx-R-H design that combines a sealing lip, a reinforced body and a retaining spring. You will find it in gearboxes, pumps and electric motors, where it protects bearings and prevents leaks. MR Industrial Accessories LLC supplies this brand and can help you confirm the right choice.

The code 8717Pol belongs to the DBH line of radial shaft seals. Its dimensions are shaft 31 mm, housing 50 mm and height 8.00 mm. The Lx-R-H designation describes a seal with a lip, a reinforced outer case and a spring that keeps the lip in contact with the shaft, making it suitable for oils and greases. Use the full designation to cross-reference the code with the manufacturer's data and check compatibility before you install it.

Seals like this one are common in rotating assemblies: gearboxes, centrifugal pumps, electric motors, spindles and belt or chain drives. They serve two purposes: hold lubricant inside the housing and block dust, water or particles that would otherwise speed up wear on bearings and bushings. In industrial settings with vibration or moderate temperatures, a correctly selected seal helps extend equipment life and reduce maintenance downtime.

During installation, check that the shaft has no burrs or marks that could cut the lip, and that the housing bore is clean and undistorted. Lubricate the lip with the same oil or grease used in the equipment, insert the seal perpendicular to the shaft and apply even pressure on the outer ring. If the shaft is worn, consider a seal with an auxiliary lip. Alignment and adequate shaft hardness are key to avoiding premature leaks.

If you need an equivalent or a different size, gather the original seal data: shaft diameter, housing diameter, height and design type. With that information, MR Industrial Accessories LLC can look for a compatible alternative within the brands we supply. You can also ask about double-lip seals, special materials such as FKM or NBR, or high-temperature configurations. The goal is to keep your production running.
