The DBH 5853 is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a fixed housing. With a 33 mm shaft, 42.50 mm housing bore and 8.00 mm width, it fits compact assemblies such as gearboxes, pumps and electric motors. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.

This seal carries the DBH code 5853. Its three key dimensions are shaft 33 mm, housing 42.50 mm and width 8.00 mm. The Lz design means a single lip with a spring, intended for rotating shafts that run with lubrication. The lip rides on the shaft while the outer case presses into the housing, forming a barrier that stops leaks and blocks dust, water and particles.

You will find seals of this size in gearboxes, centrifugal pumps, electric motors, speed reducers and other power transmission equipment. In each case the job is the same: hold oil or grease inside the assembly and keep out anything that would speed up wear on bearings and gears. It is a part that maintenance teams replace regularly in plants, factories and mobile machinery.

Proper installation starts with a clean shaft, free of burrs and scratches, and a sealing surface with the right roughness. Lubricate the lip before you push the seal in, and keep it square to the shaft by pressing on the metal case with a tube or socket, never on the lip. When choosing a seal, consider shaft speed, operating temperature and the fluid being retained. If any of those are unclear, send us your equipment details and we will help you decide.

If you need an equivalent, the fastest route is to send the full code, a photo of the part and caliper readings for shaft, housing and width. With that we can search within the same series or across other brands we carry. We can also tell you whether the Lz design is the right choice for your application.
