The DBH 5721 radial shaft seal keeps lubricant in and contaminants out of rotating shaft assemblies. It follows the Lz design, with a sealing lip and metal outer case that presses into the housing and runs against the shaft. Its dimensions are shaft 58.74 mm, housing 82.58 mm and height 12.70 mm. MR Industrial Accessories supplies this brand and helps you confirm the correct seal for your equipment.

The Lz designation tells you what you are holding: a lip seal with a metal body, made to be press-fitted into a housing bore and seal against a moving shaft. The three values to check before ordering are the shaft diameter (58.74 mm), the housing bore (82.58 mm) and the height (12.70 mm). If the shaft or bore measurement differs, the seal will not seat or seal correctly, so measure the worn part and the bore rather than relying on the old number alone.

Seals of this type are common in gearboxes, centrifugal pumps, electric motors and power transmission equipment. The job is always the same: hold oil or grease inside and keep dust, water and particles out, so bearings and gears are not exposed to premature wear. Given its dimensions, the 5721 typically fits medium-sized assemblies running at moderate shaft speeds and normal operating temperatures.

Selection involves more than the three dimensions. Consider the lubricant in use, the peripheral speed at the shaft and the service temperature, because a lip compound that does not match those conditions can harden or wear early. During installation, clean the housing and remove any burrs, lubricate the lip, and drive the seal in with a tube or spacer that presses on the outer case, never on the lip.

To quote the 5721, send the shaft, housing and height measurements, or a photo of the part. With that information we can locate the equivalent in the same brand or in another line we carry, and we can tell you whether the Lz design suits your equipment or whether a different lip or material configuration should be reviewed.
