The DBH 5981 is a radial shaft seal from the DBH line, sized for a 54 mm shaft, a 77.75 mm housing bore and a 15.80 mm height. It combines a single lip with a spring to hold lubricant in and keep contaminants out of rotating equipment such as gearboxes, pumps and power transmission drives. MR Industrial Accessories LLC supplies this part number and can help you confirm it or find an equivalent.

The 5981 seal carries the Lx designation, which indicates a single-lip, spring-loaded design for lubricated rotating shafts. The elastomer lip works with the internal spring to maintain contact under continuous operation. Shaft diameter is 54 mm, housing diameter is 77.75 mm and overall height is 15.80 mm, so the seal fits common gear reducer, pump, motor and gearbox housings.

Seals like this one protect bearings by keeping oil or grease where it belongs and blocking dust, water and particles. When a seal wears, leakage and contamination follow, which can lead to unplanned downtime. Replacing the seal at the right time is a routine maintenance task that avoids more extensive repairs.

To select the correct seal, match all three dimensions to your equipment: shaft, housing bore and height. The shaft surface should be ground and free of burrs, and the housing bore clean and undistorted. During installation, lubricate the lip with the same oil used in the machine, use a proper installation tool and never strike the seal directly.
