The DBH 6686Pol is a radial shaft seal that keeps oil or grease in and contaminants out where a rotating shaft passes through a housing. Its Lz-R design pairs a main sealing lip with a secondary exclusion lip, making it a practical choice for equipment exposed to dust and moisture. It is commonly found in gearboxes, pumps, motors, and industrial transmissions.

This seal carries the code 6686Pol within the DBH line. The dimensions to match are shaft 47.63 mm, housing 64.95 mm, and height 8.28 mm. The Lz-R designation indicates a main lip for lubricant retention plus a secondary lip that limits the ingress of outside particles. Use these three measurements and the code when checking a replacement.

Typical installations include gearboxes, centrifugal pumps, electric motors, conveyor rollers, and belt or chain drives. It also appears in road and agricultural machinery and in food processing lines, as long as the shaft and housing match the stated sizes. In each case, the seal retains lubricant and helps protect bearings from particles.

During installation, confirm the shaft is free of burrs or marks that could harm the lip, and that the housing bore has the correct diameter and finish. Apply the same oil or grease used in the equipment to the lip, then press the seal in with a support tube that contacts the outer diameter only, never the lip. In dirty environments, the secondary lip of the Lz-R design helps, but inspect the shaft and replace the seal at the first sign of leakage.

If you need an equivalent, send the complete code, the equipment make and model, or the shaft, housing, and height dimensions. We will check the DBH line and the other brands we supply for the closest match, and we can also review design variants. Accurate information helps us provide a reliable alternative quickly.
