The DBH 5142 is a radial shaft seal designed to retain lubricant and block contaminants where a shaft rotates inside a housing. It measures 38.00 mm at the shaft, 72.00 mm at the housing, and 12.00 mm in height, and it uses the Lx design. This seal is part of the seals and oil seals line that MR Industrial Accessories supplies to maintenance and purchasing teams across the United States and several Latin American countries.

The code 5142 identifies this seal within the DBH line. The three dimensions that define the fit are shaft 38.00 mm, housing 72.00 mm, and height 12.00 mm. The Lx designation refers to a single lip with a spring, a configuration intended for rotating shafts that run with lubrication. The elastomeric lip rides against the shaft while the spring keeps contact pressure steady; the metal case is press-fitted into the housing bore. Together they hold oil or grease in and keep dust, water, and particles out.

Seals with these dimensions are commonly found in gearboxes, centrifugal pumps, electric motors, conveyor rollers, and power transmission equipment. They also appear in agricultural and industrial machinery where a shaft turns inside an oil-filled housing. In each case the job is the same: keep the lubricant where it belongs and protect bearings and gears from outside contamination.

Before installation, confirm that the shaft and housing match the 38 mm and 72 mm shown in the designation. The shaft surface should be clean and free of burrs or deep marks, and it helps to lubricate the lip before sliding the seal into place. Fit the seal with the lip facing the lubricant side and press it in with a tube of the correct diameter, applying force evenly and never striking the elastomer directly. If the shaft is worn, a repair sleeve may be an option.

If you are replacing a seal and need an equivalent, send the code 5142 or the dimensions you measured. A photo of the part and the housing also helps. The team can review the DBH line and suggest the option that fits your equipment.
