The DBH 5301Sil is a radial shaft seal with a lip-and-spring configuration, identified in the source as Lz design. It sits on the rotating shaft and seals against the housing bore, keeping lubricant in and contaminants out. Its dimensions are shaft 40 mm, housing 62 mm and height 13.00 mm, a size that appears in gearboxes, pumps and other power transmission assemblies. MR Industrial Accessories supplies this brand and can help you confirm the right seal for the equipment.

Reading the code helps when you are matching a replacement. The 5301Sil number identifies the size and construction within the DBH line, while Lz tells you the seal has a sealing lip with a spring for lubricated rotating shafts. The three dimensions to verify before ordering are d 40 mm for the shaft, D 62 mm for the housing and h 13.00 mm for the height. If any of these does not match the bore or shaft on your unit, the seal will not seat or seal as intended.

This size is common in gearboxes and reducers, centrifugal pumps, electric motors, fan shafts, mixers and agricultural or industrial machinery. In each case the seal retains oil or grease inside the assembly and blocks dust, water and particles from entering. It is a good fit wherever a shaft turns continuously in the presence of lubricant.

Installation is where most seal failures start. The shaft surface should be ground, free of splines and wear, and hard enough not to damage the lip. The housing bore must be clean, without burrs, and deep enough for the 13 mm height. Lubricate the lip before fitting and press the seal in with a tool that contacts the metal edge, not the lip. On high-speed shafts, confirm that the Lz design suits the running conditions.

If you need a cross-reference for the 5301Sil, send the complete part number, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that information we can search within the DBH line or among the other brands we supply. We can also tell you if a different lip type or material is a better match for your equipment.
