The DBH 6617Pol radial shaft seal is a lip seal designed for 150 mm rotating shafts, with a 172 mm housing bore and 18.30 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in industrial equipment where the shaft rotates continuously and sealing integrity is critical to avoid downtime.

This item is a radial shaft seal from the DBH line, identified by the code 6617Pol. Its nominal dimensions are 150 mm shaft, 172 mm housing bore and 18.30 mm height. The Lx-Hel design combines a sealing lip with a helical configuration that helps return oil toward the inside of the equipment, which reduces leakage on shafts with a defined direction of rotation. It is a precision part that is press-fitted into the housing and rests its lip on the shaft.

It is used in gearboxes, pumps, electric motors, rollers and power transmission equipment where the 150 mm shaft requires lubricant containment. It also appears in continuous-process machinery, such as mixers, conveyors and industrial ventilation systems. In all these cases, the seal works alongside bearings or bushings, and its failure usually shows up as oil loss, contaminant ingress or increased temperature in the assembly.

To select it, verify that the shaft, housing bore and height dimensions match the machined housing and the dismounted shaft. Check the condition of the running surface: a scratched or out-of-round shaft accelerates lip failure. During installation, lubricate the lip with the same oil used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the original design has a direction of rotation, respect the orientation of the helical lip.

If you cannot find the code 6617Pol or need a nearby size, send us the dimensions of the old seal: shaft diameter, outer diameter and height. The code engraved on the part or a photo with a caliper next to it also works. With that data, at MR Accesorios Industriales we look for the equivalent in the same DBH line or in another brand we carry, respecting dimensions and lip type.

DBH is an official brand that MR carries, and this seal joins our line of seals and radial shaft seals for industrial replacement. If you already have the code at hand, write to us on WhatsApp and send us 6617Pol with the quantity you need. We confirm your quote with no obligation. We can also advise you if you are unsure between this design and another lip variant for your application.
