For maintenance teams working on rotating equipment, the DBH 9862Pol oil seal offers a reliable sealing solution. This single-lip radial seal is designed for a 76.30 mm shaft and a 125.35 mm bore, with a 19.40 mm height. Its A121-R construction features a metal case and an elastomer lip, effectively retaining lubricant and blocking contaminants. Commonly found in gearboxes, pumps, motors, and transmissions, this seal helps maintain system integrity. MR Industrial Accessories supplies this brand and provides expert guidance to ensure you select the correct seal for your specific application.

The DBH 9862Pol is a radial shaft seal identified by its designation and the A121-R design code. This code indicates a steel outer case with a sealing lip and a retaining spring. It is not a double-lip or mechanical seal, but a friction component that operates against the shaft and housing. The three critical dimensions are: shaft diameter (d) 76.30 mm, housing bore (D) 125.35 mm, and overall width (h) 19.40 mm. Always confirm these measurements match your equipment before installation.

Seals of this size are typically used in gearboxes, speed reducers, centrifugal pumps, medium-power electric motors, and transmission shafts. Their primary role is to keep oil or grease contained while preventing dust, water, or particles from entering. They also serve as closures on bearings and bushings that need protection from harsh environments. If your equipment experiences vibration or misalignment, inspect the shaft condition before replacing the seal.

Proper selection depends on rotation speed, operating temperature, and lubricant type. The A121-R design requires a ground shaft surface with adequate hardness; a scratched or worn shaft will leak even with a new seal. During installation, lubricate the lip with the system's oil, insert it perpendicular to the shaft, and avoid impacts. Remove any burrs or corrosion from the housing beforehand. These steps help maximize seal service life.
