The DBH 9906Pol is a radial shaft seal with an A 109-R AH design, used between a rotating shaft and its housing to keep lubricant in and contaminants out. MR Industrial Accessories supplies this brand and helps you confirm the right seal for your equipment. Its dimensions are 40.00 mm shaft, 58.00 mm housing, and 10.17 mm height, a size common in gearboxes, pumps, and power transmission units.

This seal carries the designation 9906Pol. The three key measurements are shaft 40.00 mm, housing 58.00 mm, and height 10.17 mm. The A 109-R AH design indicates a sealing lip geometry intended for rotating shafts. If your measurements match 40 x 58 x 10.17 mm, this part number is the one you need.

Seals of this size appear in gearboxes, centrifugal pumps, electric motors, rollers, and power transmission equipment. They serve two purposes: retain oil or grease inside the assembly and block dust, water, or particles from entering. In dirty or wet environments, a healthy seal helps protect bearings and avoids unplanned downtime from lubricant loss.

During installation, inspect the shaft for burrs or wear in the contact area and make sure the housing is clean and free of dents. Lubricate the lip with the same oil or grease used in the equipment, then press on the outer ring only, never on the lip. If the shaft shows a deep groove, consider a seal with an offset lip. Selection also depends on speed, temperature, and the fluid being retained.

For an equivalent, send the part number 9906Pol or the dimensions 40 x 58 x 10.17 mm by WhatsApp. A photo of the old seal with the number stamped on the lip also works. We check the designation against the manufacturer's data to offer the right option within the DBH line.
