For rotating shafts where space is tight, the DBH 6866 radial shaft seal provides a compact sealing solution. It measures 18.80 mm at the shaft, 27.00 mm at the housing and 4.76 mm in height, and is press-fitted into the housing to run against the shaft. This dynamic barrier helps retain oil or grease and keeps contaminants out of bearings and bushings. MR supplies this seal for industrial maintenance and repair work.

The seal carries the DBH brand and the designation 6866. Its dimensions are shaft 18.80 mm, housing 27.00 mm and height 4.76 mm. The Lt design indicates a single lip with a spring, intended for rotating shafts lubricated with oil or grease. In the 6866 code, the numbers correspond to that specific dimensional combination. A metal case and an elastomeric lip are bonded into one rigid unit that presses into the housing bore.

You will find this seal in small gearboxes, centrifugal pumps, low-power electric motors, gear reducers and transmission equipment. It also appears in agricultural machinery, conveyors and hydraulic systems where lubricant must stay in and dust or water must stay out. Because the seal is compact, it suits assemblies with limited axial space that still need reliable sealing at moderate speeds.

When selecting a replacement, confirm that the shaft diameter is within the recommended tolerance and that the housing bore has the correct surface finish. Install with a uniform pressure tool, lubricate the lip and avoid impacts that could damage the sealing edge. Shaft runout and operating temperature influence service life; for high temperature or high peripheral speed, consider a different compound. Always compare the full designation before replacing.

If you need an equivalent, send the original code, a photo of the part and dimensions measured with a caliper. With that information we can search our seals and radial shaft seals line for the option that best fits, whether from the same brand or another that performs the same function. We can also advise on the most suitable lip design for your lubricant and working conditions.
