The DBH 5746 is a radial shaft seal engineered to keep lubricant in and contaminants out of rotating equipment. With an Lx design and dimensions for 85.73 mm shafts and 111.16 mm housings, it fits gearboxes, pumps, electric motors and transmissions where leak control and protection from dust or water are essential. MR Industrial Accessories supplies this brand and can help you select the right seal.

This seal features an Lx configuration, which combines a main sealing lip with an auxiliary dust lip for added defense against external particles. A stainless steel spring maintains steady contact pressure on the shaft. The elastomer is formulated to resist mineral oils and greases. Key dimensions are shaft 85.73 mm, housing 111.16 mm and height 19.84 mm.

Common installations include gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In each case, the seal prevents lubricant loss and blocks contaminants that would otherwise accelerate wear on bearings and gears. It also suits food, chemical and petrochemical equipment where fluid containment is critical. The size works well for medium and large shafts found in heavy machinery and production lines.

During installation, inspect the shaft for burrs or marks that could harm the lip, and lubricate the lip with the same oil or grease used in service before sliding it into place. The housing must be clean and undistorted; proper surface roughness helps the seal seat correctly. When choosing a replacement, factor in shaft peripheral speed, operating temperature and chemical compatibility between the elastomer and the fluid being sealed. If your original seal has a different design, contact MR to evaluate an equivalent.
