The DBH 5755 is a radial shaft seal designed to retain lubricant on a rotating shaft while keeping out dust, water, and other contaminants. With a 12.70 mm shaft diameter, 31.75 mm housing diameter, and 9.52 mm height, this Lx design seal is a common replacement for small-shaft equipment. MR Industrial Accessories LLC supplies this brand and can help you select the right seal for your application.

This seal is identified by the designation 5755. The dimensions are: shaft diameter 12.70 mm, housing diameter 31.75 mm, and height 9.52 mm. The Lx design indicates a single-lip seal with a spring, intended for rotating shafts with lubrication. Knowing the series nomenclature helps you quickly find the part in a catalog and compare it to the original size before replacement.

Typical uses for this size include pumps, small electric motors, gearboxes, compressors, machine tools, and power transmission equipment with small-section shafts. They are also found in agro-industrial and process equipment where the seal must contain oil and prevent water and dirt ingress. If the seal operates in an environment with abrasive dust, inspect the lip and shaft condition before installing a new one.

For proper installation, ensure the shaft has no burrs or scoring in the contact area, as a damaged surface can ruin the lip quickly. Lubricate the lip with the same grease or oil used in the equipment, and press the seal in perpendicular to the shaft without side impact. If the housing has a shoulder or the shaft is misaligned, the seal may fail even with correct dimensions.

To request a quote for code 5755, provide the shaft, housing, and height dimensions, along with a photo of the old seal if available. This information allows us to check for an alternative within the same series or from another brand we carry. Mentioning the equipment type and lubricant used also helps refine the selection.
