The DBH 8164 is a radial shaft seal with an Lz design, featuring a single sealing lip and a metal outer body. It is sized for a 19 mm shaft, a 28.67 mm housing bore, and a 5.50 mm overall height. This seal is used to retain oil or grease and to keep dust and moisture out of rotating equipment, making it a common replacement part in pumps, motors, and gearboxes.

The Lz designation indicates a single-lip configuration, which is suited to shafts running at moderate peripheral speeds. The lip is made from an elastomeric compound that resists oil and the temperatures typically found in industrial service. The metal case allows the seal to be press-fitted into the housing bore. The code 8164 identifies this particular size within the DBH catalog.

Typical applications include centrifugal pumps, electric motors, reducers, gearboxes, bearing housings, and spindles. In these positions, the seal prevents lubricant from escaping and protects bearings from external contamination. It is often found in agricultural machinery, process equipment, and pumping systems where axial space is limited.

When selecting a replacement, confirm that the shaft diameter, housing bore, and height match the DBH 8164. During installation, apply the same oil used in the equipment to lubricate the lip, and check that the shaft is free of burrs or scratches that could damage the sealing edge. Keep shaft eccentricity to a minimum to support seal life.
