The DBH 8238 is a radial shaft seal that keeps lubricant in and contaminants out by seating on the shaft and inside the housing. With a shaft diameter of 148 mm, a housing diameter of 170 mm and a height of 15.00 mm, it fits equipment that uses large-diameter shafts. Its Lx-Hel design adds an auxiliary lip for extra protection where dust or dirt is present.
This seal is identified by the numeric code 8238 and belongs to the DBH line. The three dimensions you need to confirm are shaft 148 mm, housing 170 mm and height 15.00 mm. The Lx-Hel designation means the seal has a second, exclusion lip, so it is intended for locations where outside particles can shorten seal life. A spring-loaded elastomer lip maintains contact under continuous rotation.
You will typically find this size in gearboxes, centrifugal pumps, mills, mixers and power transmission equipment that runs on 148 mm shafts. It also appears in agricultural machinery, conveyors and centralized lubrication systems. Because of its dimensions, it is common on large industrial drives where a reliable barrier against oil loss and dirt entry is important.
Before installation, make sure the shaft and housing are clean and free of burrs or scratches. Apply the same oil used in the equipment to the lip, then press the seal in squarely with a proper installation tube, taking care not to damage the lip. When selecting a seal, consider peripheral speed, operating temperature and how the elastomer reacts to the fluid being sealed.
If you are looking for an equivalent, send the part number 8238 or the shaft and housing dimensions. The team can suggest options from the DBH line and help you confirm the right choice. Installation tools and lubricants are also available to make the job easier.
