The DBH 9363 is a radial lip seal built to hold lubricant in and keep contaminants out of assemblies with a turning shaft. With an Lx design and a size of 30 mm shaft, 58 mm housing and 8 mm height, it suits gearboxes, pumps, electric motors and transmissions running on oil or grease. MR supplies this brand and can confirm the size before quoting.

This seal belongs to the DBH line and carries the code 9363. The dimensions are shaft 30 mm, housing 58 mm and overall height 8.00 mm. Its Lx design refers to a single lip with spring, made for rotating shafts with internal lubrication. The manufacturer's markings are stamped on the part itself, so the same seal can be identified and reordered without confusion.

Typical applications are equipment where oil or grease has to stay inside while dirt stays outside. That includes gearboxes, centrifugal pumps, electric motors, conveyor rollers, mixers and belt or chain drives. It is also a common replacement on older machines whose original assembly is no longer offered, when the loose seal is sourced by its dimensions instead.

During installation, verify that the shaft is free of burrs and wear and that the bore is clean and undented. Coat the lip with the same oil or grease used in the equipment, then press on the outer ring only, never on the lip. If the shaft shows a deep groove, a seal with the lip in a different position is worth considering. Speed, temperature and fluid type all influence the selection, so keep that data on hand.

For an equivalent, send the shaft diameter, housing diameter and height you measured, plus a photo of the old seal if you have one. With that information we review options within the same DBH line or other brands we carry. We can also advise when the housing is damaged and a repair sleeve or a seal with a reinforced case should be evaluated.

To request a quote for the DBH 9363, send the code on WhatsApp or by email to MR along with the quantity you need. If the size is unclear, write to us anyway and we will help you confirm it against the manufacturer's data. We handle technical inquiries on bearings, seals, power transmission and bearing housings so you order once and get the right part.
