The DBH 6688 is a radial shaft seal built to keep lubricant inside a housing and keep dust, water and other contaminants out. Its three key measurements are a 34.93 mm shaft, a 61.90 mm bore and a 7.54 mm width, which places it among the low-profile lip seals. MR Industrial Accessories supplies this brand and helps you confirm the right reference for your equipment.

Code 6688 sits in the DBH line of radial shaft seals, and the Lz designation tells you which lip and case geometry the part uses. Read the number in this order: 34.93 mm is the shaft it runs on, 61.90 mm is the housing bore it presses into, and 7.54 mm is the overall width. Checking those three figures against the machine before you pull the old seal is the fastest way to avoid a wrong fit. This is a seals and oil seals item, meant for rotating shafts that carry oil or grease.

You will find seals like this one in gearboxes, pumps, electric motors, rollers and power transmission assemblies. In each case the job is the same: hold the lubricant in, keep grit and moisture out. Because the 7.54 mm width is compact, it suits housings where there is little room along the shaft. Agricultural equipment, plant machinery and continuous-process lines all rely on this kind of seal to keep unplanned stoppages down.

Before ordering, confirm the shaft measures 34.93 mm and the bore 61.90 mm, and that the housing depth takes the 7.54 mm width. The Lz design affects how the lip sits and how it handles pressure, so it matters when you match a replacement. At installation, coat the lip with lubricant, keep burrs and sharp splines away from it, and check the shaft surface. A worn shaft can often be brought back with a repair sleeve.
