The DBH 8834 is a radial shaft seal sized for large-diameter shafts: 280 mm shaft, 320 mm housing bore and 20.00 mm height. Its Lz variant carries a main lip plus a secondary exclusion lip, so it holds lubricant in while keeping moderate dust out. Gearboxes, mills and process pumps are the usual places you will find it.
Reading the code is straightforward. The 8834 number is the commercial designation used to order the replacement, and the dimensions follow the standard order: shaft 280 mm, housing 320 mm, height 20.00 mm. The Lz designation tells you the lip arrangement, with the auxiliary lip acting as the dust-side barrier. Keep all three dimensions together when you look for a replacement, since the seal only works if the bore depth matches the 20.00 mm height.
Seals of this size sit in large gearboxes, ball and rod mills, process centrifugal pumps, industrial mixers, and mining or cement equipment. In each case the job is the same: keep oil or grease from escaping along the shaft and stop particles from reaching the bearings and gears, where they would speed up wear.
Before pressing a new seal in, inspect the shaft for burrs or deep marks in the sealing zone and confirm the housing is clean and undistorted. The lip needs the right surface hardness and roughness to run properly; a badly worn shaft may call for a repair sleeve. Lubricate the lip with the oil or grease used in the equipment, seat it square, and do not strike it or fit it backwards.
If you need an equivalent, send the full code together with the shaft, housing and height measurements. With that information we can check an alternative brand or confirm whether a different lip design is available, including spring-loaded lips or non-standard materials.
