For rotating shafts that need reliable lubricant retention and protection against contaminants, the DBH 5112Sil radial shaft seal offers a compact Lz design. Its dimensions—25.40 mm shaft, 44.50 mm bore, 5.00 mm height—suit equipment where space is limited. MR supplies this seal and helps you confirm the right fit for your application.
This seal is identified as DBH 5112Sil and belongs to the DBH line. The Lz designation indicates a single-lip construction with a spring, intended for lubricated shafts. Before ordering, verify that your shaft diameter is 25.40 mm, the housing bore is 44.50 mm, and the width is 5.00 mm. A seal with different dimensions will not perform correctly, even if it appears similar.
Typical uses include electric motors of low to medium power, gear reducers, centrifugal pumps, small compressors, fan shafts, and general power transmission equipment. It also appears in machine tools and agro-industrial machinery where oil or grease must stay inside and dirt must stay out. The seal works on a rotating shaft inside a machined housing, with the lip in continuous contact.
During selection and installation, consider shaft speed, operating temperature, and lubricant type. Lubricate the lip before assembly and use a proper installation tool to avoid damage. Inspect the shaft surface: wear, scratches, or burrs in the sealing area will shorten seal life. The Lz spring helps maintain contact, but a smooth, polished shaft is essential for long service.
If you need an equivalent, send part number 5112Sil along with your shaft and housing dimensions. A photo of the old part or the assembly drawing is also helpful. With that information, we can review alternatives within the DBH line or from other brands we supply, respecting the mounting dimensions. Even without the exact part number, correct dimensions allow us to assist you.
