The DBH 8502Pol is a radial shaft seal with a single main lip and an additional dust lip, identified as the Lx-R design. It fits a 70 mm shaft, a 92 mm housing bore, and an 8.50 mm height, and is used to keep lubricant in and contaminants out of gearboxes, pumps, and similar transmission equipment.

In this seal, the elastomer lip runs against the rotating shaft while the outer diameter presses into the housing to form a static seal. The Lx-R designation means there is a primary sealing lip plus an external lip that helps block dust, water, or particles. As a wear part, the lip can harden, tear, or lose elasticity over time, leading to oil leakage along the shaft.

This size appears in parallel-shaft gearboxes, centrifugal pumps, mixers, conveyors, and chain or belt drives. It is also found in agricultural machinery and process lines where oil or grease must be retained in a bearing. The dust lip is particularly useful when the equipment operates around dust, chips, or mud, as it keeps contaminants away from the main lip.

Proper installation starts with checking the shaft for burrs, scratches, or wear. A deep groove on the shaft will prevent sealing even with a new seal. Lubricate the lip before fitting, and press the seal in squarely without hitting the elastomer directly. When selecting a seal, consider shaft speed, operating temperature, and the fluid being retained. For equipment with high vibration or eccentricity, a more rigid design may be needed.

To find an equivalent, provide the part number 8502Pol along with the shaft, housing, and height dimensions from your equipment. With that information, we can look for alternatives within the DBH line or other brands we supply and identify a compatible option. We can also cross-check against the manufacturer's data sheet for critical applications where installation risk must be minimized.
