The DBH 9821 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It is press-fitted into a housing and its lip runs against the shaft, so the fit and shaft condition matter as much as the seal itself. The design is A 053, and the size is given as shaft 30 mm, housing 45 mm, height 16 mm.

Read the size in the same order the code implies: the 9821 designation corresponds to a 30 mm shaft, a 45 mm housing bore and a 16 mm height. The 16 mm height gives a wider seating band in the housing, which helps keep the seal square during installation. The outer diameter is fixed in the housing while the lip contacts the rotating shaft.

Typical uses include gearboxes, pumps, electric motors, mixers and conveyors, as well as equipment exposed to dust or splashes. In maintenance work it is often fitted during repair of process or agricultural machinery. The radial lip design suits moderate speeds and continuous operation.

Before ordering, confirm the shaft, housing and height dimensions with a caliper. Inspect the shaft surface for grooves or wear that could damage the lip, and check that eccentricity and play are within tolerance. Lubricate the lip and use an installation tool to avoid deforming the seal.

If you need an equivalent, send the part number 9821 or your shaft and housing dimensions by WhatsApp or email. The team can look for alternatives in the same brand or in others, and can advise if the mounting space allows a different height. Photos of the housing also help confirm the correct part.
