The DBH 8081 is a radial shaft oil seal designed to retain lubricants and block contaminants in rotating equipment. With a 25 mm shaft, 35 mm bore, and 8 mm width, it fits common industrial housings. The Lr configuration—single lip with a garter spring—works well on lubricated shafts under low pressure, making it a practical choice for gearboxes, pumps, and motors.

This seal is identified by part number 8081. Key dimensions are shaft 25.00 mm, housing 35.00 mm, and height 8.00 mm. The Lr design features a single sealing lip backed by an internal spring, which maintains contact with the shaft during operation. The elastomer and spring combination provides reliable sealing in continuous duty.

Typical installations include gearboxes, centrifugal pumps, electric motors, compressors, and conveyor rollers. In these applications, the seal prevents oil or grease loss and keeps dust and moisture away from bearings. It is also found in agricultural and general industrial machinery where the shaft rotates at moderate speeds and surface finish is good.

Before installation, confirm the shaft has a minimum hardness of 45 HRC and roughness below 0.8 µm Ra. The housing bore should be clean, free of burrs, and have a lead-in chamfer. Coat the lip with lubricant prior to assembly and avoid hammering on the seal. If the shaft is worn, a wear sleeve or repositioning the lip may be needed. Selection depends on speed, temperature, and lubricant type.
