The DBH 6589 is a radial shaft seal sized for large rotating equipment. Its lip rides against the shaft while the outer body seats in the housing, so lubricant stays inside the assembly and outside contamination stays out. The dimensions are shaft 103 mm, housing 166 mm and height 15.00 mm, with the Lz lip and body configuration. Gearboxes, pumps, mills and power transmission units built around 103 mm shafts are the usual homes for this size.

The number 6589 identifies this seal within the DBH line. Reading the size callout is straightforward: 103 mm is the shaft diameter the lip contacts, 166 mm is the bore it presses into, and 15.00 mm is the overall height. The Lz designation describes how the lip and seal body are arranged. A garter spring inside the lip keeps steady pressure on the shaft, which is what maintains the sealing contact as the shaft turns.

Seals in this size range turn up in gearboxes, speed reducers, centrifugal pumps, mills, mixers and similar power transmission equipment running 103 mm shafts. Their job in those assemblies is to hold oil or grease in place and keep dust, water and particles away from the bearings. When the seal does that job, bearings last longer and unplanned downtime drops.

Before ordering, confirm that the shaft and housing dimensions match the seal and that the 15.00 mm height fits the cavity depth. The Lz design also sets the lip geometry and which way it faces. On installation, coat the lip with lubricant, drive the seal in with a proper tool rather than a hammer, and check the shaft for burrs, nicks or wear at the contact band.
