The DBH 5129 is a radial shaft seal built for rotating shafts. Its designation 52x72x10 tells you the three critical dimensions: a 52 mm shaft, a 72 mm housing bore and a 10 mm width. The Lx configuration uses a single lip with a spring, which helps hold lubricant in and keep contaminants out. You will find this seal in gearboxes, pumps, motors and other power transmission equipment. MR Industrial Accessories supplies the DBH brand and can help you confirm the right seal for your application.

When you read the code 5129, the numbers that matter are the bore, the outside diameter and the height: shaft 52.00 mm, housing 72.00 mm, width 10.00 mm. The Lx design is a single-lip seal with a garter spring, made for lubricated rotating shafts. DBH is one of the brands we carry, so if you need a cross-reference we can look at other series or manufacturers that match those three dimensions.

Seals like the 5129 show up in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In each case the job is the same: keep oil or grease where it belongs and block dust, water and particles from getting in. Because the lip runs against the shaft, it wears over time. Watch for drips, weeping or unusual noise around the seal area as signs that replacement is due.

Installation matters as much as selection. Check that the shaft surface is clean and within the recommended hardness and roughness, and that the housing bore is free of burrs or scratches. Put a light film of lubricant on the lip before you press it in, and use a proper driver so you do not distort the metal case. Shaft speed, operating temperature and the fluid being sealed all affect how long the seal will last.
