For rotating shafts that need a dependable barrier against lubricant loss and outside contamination, the DBH 5349 radial shaft seal is a direct-fit wear component. It works in a cylindrical housing bore and contacts the shaft through a flexible lip, so it can be swapped out during routine service. The size callout is shaft 50.80 mm, housing 69.88 mm and width 12.70 mm.

This seal is listed under part number 5349 in the DBH line. The Lz designation describes a single lip with a spring, a common choice for oil- or grease-lubricated rotating shafts. Because the lip is spring-loaded, it keeps steady contact with the shaft surface. The elastomer body and the spring work together to hold lubricant in and keep dust, water and particles out, depending on how the seal is fitted.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. It also suits agricultural and road machinery, where weather exposure makes scheduled seal replacement part of normal upkeep. Shafts near 50 mm running at moderate speeds are the usual match. Treat it as a wear part: inspect it at every maintenance interval and replace it when the lip shows hardening, cuts or leakage.

When matching a seal, confirm three measurements against the equipment: the shaft diameter, the housing bore and the housing depth. The height must fit the bore depth, and the shaft surface should be ground and free of splines under the lip. Lubricate the lip with the same oil used in the assembly, then press the seal in with an installation tube. Keep it square, avoid impacts and check concentricity before running the equipment.

If the DBH 5349 is not the exact fit, we can look at equivalents from other brands or search by dimensions: shaft, outer diameter and height. A double-lip version or one with a dust guard may be an option if the application calls for it. A photo of the old seal or caliper readings helps us identify the right replacement.
