The DBH 9543 is a radial shaft seal that sits in the housing and works against the shaft, holding lubricant in and keeping dust, water and particles out. Its Ls design is a single sealing lip with a spring, made for rotating shafts on industrial equipment. Gearboxes, pumps, electric motors and transmissions rely on seals like this one to protect bearings and gears. MR Industrial Accessories supplies this brand and quotes it by part number.

Part number 9543 identifies this DBH seal. Reading the size code gives shaft 59.40 mm, housing 86.00 mm and height 5.00 mm. The Ls design points to one sealing lip with a spring, which suits lubricated rotating shafts. At 5.00 mm tall, the seal stays compact where axial room is tight. Confirm both the shaft and housing diameters before installation, since any mismatch changes how the lip seats.

A seal in this size range shows up in gearboxes, centrifugal pumps, electric motors, spindles and transmission equipment. In each case it keeps oil or grease from leaking out and stops contaminants from reaching the bearings. You will also find it on agricultural machinery, material handling equipment and process lines where shafts see dust or moisture. Where dirt is heavy, check the lip condition on a regular basis.

Selection depends on shaft speed, working temperature and the lubricant in use. The Ls design with spring fits moderate speeds and low pressures. During mounting, lubricate the lip, make sure the shaft is free of burrs and marks, and keep the housing clean. Press the seal in perpendicular, without hammering that could distort the lip. If the shaft is worn, look at an offset lip seal or a repair sleeve.

For an equivalent, send part number 9543 or the dimensions taken from the old seal. We can search within the same DBH brand or across other brands we supply, keeping the shaft, housing and height dimensions unchanged. We can also tell you whether the Ls design fits your application. Details such as equipment type, lubricant and temperature help us give you a better answer.
