The DBH 9729 is a radial shaft seal built to sit on a rotating shaft and inside a housing cavity, holding lubricant in and keeping dust, water and particles out. Its three key measurements are 82.50 mm at the shaft, 101.60 mm at the housing and 9.50 mm in height, and it comes in the Mx design. It is a replacement item for rotating equipment, where a seal that fits and seats properly is what keeps bearings and bushings from wearing out early.

This seal belongs to the DBH line and carries the code 9729. Read the dimensions in the order they are normally checked: shaft 82.50 mm, housing 101.60 mm, height 9.50 mm. The Mx design refers to a sealing lip combined with a metal body, the arrangement used to retain oil or grease along a rotating shaft. Because the lip runs directly against the shaft and the outer edge presses into the cavity, the measurements have to match the original assembly exactly.

Typical installations include gearboxes, pumps, electric motors, rollers and power transmission equipment, as well as agricultural machinery, conveyors and hydraulic systems where a shaft turns inside a housing and the lubricant has to stay separated from the surrounding environment. Since the lip wears over time, the practical approach is to replace the seal once leaking, unusual noise or shaft play shows up, before the condition spreads to bearings or bushings nearby.

Before ordering, confirm that the shaft diameter, housing diameter and height correspond to your equipment. The shaft surface also matters: it should be clean, free of burrs and grooves, and hard enough that it does not damage the lip. When installing, coat the lip with the same grease or oil the system runs on, press the seal in squarely and avoid striking it. If the shaft is already worn, a seal with an auxiliary lip is worth evaluating.

To request a quote for code 9729, send the shaft and housing dimensions, a photo of the part and the lubricant type used in the equipment. With those details we can search for an alternative in the DBH line or among other brands we supply, or propose a seal with similar characteristics. We can also help when the housing is a special design or the original seal is no longer available.
