The DBH 5171 is a radial shaft seal sized 32 mm shaft, 55 mm housing and 8.00 mm height. Its Lz design is a single-lip seal with spring, built for rotating shafts with internal lubrication. It keeps oil or grease in and keeps dust, water and particles out of gearboxes, pumps, motors and transmission equipment that run on 32 mm shafts.

Reading the code and dimensions: the DBH 5171 number identifies this seal, while 32 mm is the shaft diameter it runs on, 55 mm is the housing bore and 8.00 mm is the height. The Lz design tells you it has one sealing lip with a spring, which is the usual choice for rotating shafts lubricated from inside the housing. The lip contacts the shaft while the outer case presses into the housing.

Where it fits: you will find this size in gearboxes, centrifugal pumps, electric motors, speed reducers and power transmission equipment. In each case the seal retains lubricant and shields bearings and gears from contaminants. Because the 8 mm height is compact, it suits equipment with limited axial space that still needs dependable sealing on a 32 mm shaft.

Installation and selection: check that the shaft and housing match 32 mm and 55 mm, and that the shaft surface is clean and free of burrs or scratches. Lubricate the lip before fitting the seal, then press it in with a suitable tool, keeping force even on the case. When selecting, account for rotation speed, working temperature and the lubricant in use; our team can help if you are unsure.

Equivalents and quotes: if you need a replacement, send the DBH 5171 code or your shaft and housing dimensions. We can also check other brands or configurations when the Lz design is not the right fit. Message us on WhatsApp or by email with the part number and we will reply promptly.
