The DBH 5977 is a radial shaft seal built to hold lubricant in and keep contaminants out of rotating equipment. Its Lx configuration uses an elastomer lip with a metal spring, and the elastomer compound resists oils and greases. Shaft, housing and height dimensions are confirmed, so the seal can be matched directly to the bore and shaft it serves.

Dimensions to confirm before ordering: shaft 49.20 mm, housing 76.22 mm, height 17.85 mm. The code 5977 sits inside the DBH line, which makes it easy to look up in a catalog or purchasing system and cross it against what is currently installed. The Lx designation tells you this is a single-lip seal with a spring, intended for lubricated rotating shafts.

You will find this profile in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In each case the seal keeps oil or grease where it belongs and blocks dust, water and particles from reaching bearings and gears. Machine tools and power transmission assemblies with moderate shaft speeds are also common homes for it, and the compact section fits where mounting space is tight.

Installation is straightforward when the basics are respected. Clean the shaft and housing and check for burrs or scratches. Lubricate the lip with the same oil or grease the equipment runs. Press evenly on the outer ring only, never on the lip. If the shaft is worn, consider a repair sleeve. Speed, temperature and fluid type drive selection, so share those details if you are unsure.

For a replacement or an equivalent, send the code 5977, the dimensions of the seal being replaced, or a photo of the part and the housing. We compare against the DBH line and suggest options. Exact dimensions matter here: a mismatch in any of the three measurements will compromise sealing and lead to early leaks.
