When lubricant starts weeping past a shaft end, the DBH 8493 radial shaft seal is the part that stops it. This lip seal presses into the housing bore and rides on the rotating shaft, keeping oil or grease where it belongs while blocking dust and other contaminants from getting in. Its measurements are 15 mm at the shaft, 32 mm at the housing and 7 mm in height, which makes it a common fit in gearboxes, pumps and electric motors.

The seal carries the DBH brand and part number 8493. Reading the size callout is straightforward: d equals 15.00 mm for the shaft, D equals 32.00 mm for the housing bore and h equals 7.00 mm for the height. The Lz designation refers to the lip profile, built to hold lubricant in place. An elastomer lip presses lightly against the shaft to close the gap, while the metal outer case holds the seal firmly in the housing.

You will find this type of seal on rotating shafts in gearboxes, centrifugal pumps, electric motors, compressors, spindles, and belt or chain drives. Its job is twofold: keep oil or grease inside the mechanism and keep dust, water and particles out. Seals like this one protect the bearings and gears around them, and a failed seal often shows up as a leak or as premature wear elsewhere in the assembly.

Choosing the right seal starts with confirming the shaft and housing dimensions, then checking the lubricant type, the operating temperature and the rotation speed. The Lz design works with grease or oil lubrication at moderate speeds. At installation, coat the lip with lubricant, use a tool that will not cut or distort the seal, and make sure the shaft surface is free of burrs and marks. A clean housing bore matters just as much for a reliable seal.
