The DBH 9428 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft passes through a housing. It measures 44 mm at the shaft, 72 mm at the housing and 8.00 mm in height, dimensions that fit gearboxes, pumps and other power transmission equipment. MR supplies this DBH seal and can help you confirm the right lip and elastomer for your operating conditions.

The part number 9428 identifies a DBH radial shaft seal with an Lx design: a single lip with a spring, made for rotating shafts that run with lubrication. The three dimensions to check are shaft 44 mm, housing 72 mm and height 8.00 mm. At the time of quoting, the elastomer and spring are confirmed against the manufacturer's product page.

Seals in this size range are common in gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment, as well as in agricultural and industrial machinery exposed to dust, water or oil. Their job is twofold: hold the lubricant inside and block particles that would otherwise wear bearings and bushings.

During installation, confirm that the shaft and housing diameters match the values above and that the shaft surface is clean and free of burrs. Lubricate the lip before pressing the seal in, and use an installation tool that contacts the outer edge only, never the lip. If the shaft is worn, an offset lip seal may be an option. Speed, temperature and the fluid being retained determine the correct lip material.

To find an equivalent to the DBH 9428, send the part number and dimensions to the MR team by WhatsApp or email. We can also review cases where the shaft or housing is outside standard tolerances. For that, provide the measured shaft diameter, housing diameter and width, plus a photo of the housing and the old seal. With those details, we quote the DBH option or another brand we carry.

MR Industrial Accessories LLC supplies seals, bearings, mounted units and housings, power transmission parts, lubrication and maintenance tools to customers in the United States and several Latin American countries. If the DBH 9428 is for equipment in service, send the part number and we will reply promptly with a quote and material options, along with guidance on installation and lip care.
