The DBH 8551Pol is a single-lip radial oil seal with a spring, built for rotating shafts. It keeps lubricant in and contaminants out, protecting bearings and gears. Pressed into the housing and running against the shaft, it maintains a thin oil film for sealing with low friction. Common in pumps, motors, gearboxes and transmission equipment.

Dimensions are shaft 58 mm, housing 75 mm and width 9 mm. The Lx-R design pairs a spring-loaded sealing lip with an outer elastomer cover, which eases installation and supports sealing in standard-tolerance housings. The 8551Pol code identifies the lip geometry and material, suited to mineral oils and moderate temperatures.

You will find this seal in centrifugal pumps, electric motors, speed reducers, transmission shafts and process equipment. In each case it shields bearings and gears from premature wear caused by contamination. It also fits agricultural and industrial machinery where space is tight and sealing must be reliable.

Selection starts with confirming shaft and housing dimensions. The shaft needs adequate hardness and controlled roughness to avoid leaks. During installation, lubricate the lip with the same oil used in the equipment, check that the spring sits correctly, avoid impacts and confirm housing concentricity.
