For equipment running a 150 mm shaft, the DBH 6617Pol radial shaft seal provides a sealing point that keeps lubricant in and contaminants out. It fits a 172 mm housing bore with an 18.30 mm height, so it is a direct replacement where those dimensions match the machined seat and the shaft.

The seal carries the DBH code 6617Pol and uses the Lx-Hel lip design. That configuration includes a helical feature on the lip that directs oil back toward the inside of the assembly as the shaft turns in its defined direction. The result is a seal suited to rotating equipment where the shaft runs continuously and the lip must maintain contact without letting oil escape.

You will find this size in gearboxes, pumps, electric motors, rollers and other power transmission assemblies. It also appears in mixers, conveyors and industrial ventilation units. In each case the seal works alongside bearings or bushings, and a worn lip typically shows up as oil loss, dirt entering the housing or a rise in operating temperature.

Selection starts with the three basic measurements. Confirm the shaft diameter is 150 mm, the housing bore is 172 mm and the height is 18.30 mm. Inspect the shaft surface where the lip runs: scratches, wear grooves or an out-of-round condition will shorten seal life. If the original part has a direction of rotation, note the orientation of the helical lip before removal.

During installation, apply the same oil used in the equipment to the lip, press the seal in squarely and avoid hitting it directly. A seal driven in at an angle can leak even when the dimensions are correct. For a quote, send the code 6617Pol along with the quantity, or provide the shaft, outer diameter and height of the old seal, or a photo of the part next to a caliper.

MR supplies DBH seals as part of its line of seals and radial shaft seals for industrial replacement. If you are unsure whether this lip variant fits your application, the team can suggest an equivalent within the DBH line or from another brand we carry, always respecting dimensions and lip type.
