The DBH 8158 is a radial shaft seal built to keep lubricant in and contaminants out where a shaft turns. Its dimensions are shaft 111.31 mm, housing 142.80 mm and height 4.92 mm, which suits assemblies that leave little room along the axis. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your machine.
This seal carries the DBH code 8158 and the A 045 design, a single lip with a spring that rides against a rotating shaft. Because it contacts both the shaft and the bore, its performance depends on how those two surfaces are sized and finished. Check the tolerances and surface condition of the shaft and housing before you order.
Seals of this type appear in gearboxes, pumps, electric motors, rollers and other power transmission equipment. They hold oil or grease inside the assembly and block dust, water and particles that would otherwise speed up wear on bearings and gears. When the shaft is large and axial space is tight, a low-height seal like this one is a practical way to keep lubrication where it belongs.
Installation calls for matching the measured shaft and housing diameters to the figures above. The shaft should be free of burrs, with hardness and roughness that will not harm the lip. Coat the lip with the same oil the equipment uses, then press the seal in with a tool that spreads force evenly across the outer ring. Never hit the seal directly, since that can distort the lip or the spring.
If you need a replacement for the DBH 8158, send us code 8158 or your current measurements. We can look for equivalents in other brands or lip configurations within our seal range and suggest the design that fits your speed, temperature and lubricant. Quotes go out by WhatsApp or email, and our team can also help you verify that this model suits your application.
