Part DBH 6042 is a radial shaft seal from the DBH line, built to sit on a rotating shaft and inside a housing bore. It keeps lubricant where it belongs and keeps dust, water and other contaminants out of the assembly. The Lx design uses a single lip with a spring. Shaft side measures 88.9 mm, housing side 114.27 mm, and the seal is 14.28 mm wide.

Reading the code helps when you compare it against a drawing or a worn part pulled from a machine. The 6042 designation ties the seal to one specific size in the DBH range, and the three figures below it tell you whether it will fit: 88.9 mm for the shaft, 114.27 mm for the housing bore, 14.28 mm for the width. The Lx marking describes the lip arrangement, a single lip backed by a spring.

In service, the elastomer rides against the shaft while the spring holds steady contact, which lets the lip follow small amounts of shaft movement and runout. That combination is why seals of this type turn up in gearboxes, pumps, electric motors, rollers and other transmission equipment. Two jobs happen at once: oil or grease stays inside, and outside contamination stays out. On reducer output shafts and bearing supports, that protection is often what decides how long the bearing lasts.

Choosing a replacement comes down to matching the bore, the shaft and the space you have for width. Operating speed, temperature and the fluid being sealed also shape the decision. Lx seals work with grease or oil lubrication at moderate speeds. If the shaft surface is scored or worn, an auxiliary lip or a wear sleeve is worth considering instead of a straight swap.
