The DBH 1263 is a radial lip seal that stops oil or grease from escaping where a rotating shaft passes through a housing. Its A 414 design pairs a sealing lip with a metal outer body that presses into the cavity. Gearboxes, pumps, electric motors and reducers rely on seals like this to contain lubricant and keep dust and water out. MR Industrial Accessories supplies this brand and can help you confirm the right size.

This radial shaft seal carries the code DBH 1263. Its dimensions are: shaft 31 mm, housing 43 mm, height 8.00/14.00 mm. Design A 414 means a sealing lip with a sheet metal body for press-fit installation. The two height figures tell you the sealing section measures 8 mm, while the assembly with the outer flange reaches 14 mm, so it can sit in cavities with different shoulder depths. Always check these values against your equipment before ordering.

Seals of this size show up on transmission shafts, centrifugal pumps, electric motors, gearboxes and process equipment. Their job is to hold lubricant in and keep contaminants out. Because the lip gradually hardens or wears, leaks eventually appear. Inspect the seal during preventive maintenance and replace it as soon as you notice a starting leak or axial play in the shaft.

During installation, confirm the shaft matches the specified size and has no burrs or marks, and that the housing is clean and undistorted. Coat the lip with the same oil or grease used in the equipment, then press it in with a support tube that contacts the metal edge, never the lip. If the shaft is worn, consider a seal with an auxiliary lip. Speed, temperature and lubricant type all affect selection; if you lack that data, ask us and we will guide you.

For an equivalent, send the code 1263 or your current dimensions (shaft, housing and height) through WhatsApp. A photo of the old seal or the housing drawing also works. We compare that information with available options and confirm compatible alternatives.
